7.1 - Not exactly off the rack

by kftool on All Out Assault

Description

how does one go about assembling a system that can qualify to be listed in the category,"ALL OUT ASSAULT." One way is to read up on a few years of "recommended components" lists from the high end magazines and venture out, with a fat wallet, to visit a few premium audio salons. By just BUYING the top products on the lists, you'll certainly make the audio salons happy , and hopefully, even you may be satisfied by owning the best money can buy. Having years of personal experience in owning many types of excellent audio gear adds a level of surety that only experience can add. Going through this process often enough, you may come to the conclusion that you may never get "THE MIXTURE " that you've been looking for. As the saying goes,"If you want it done right, do it yourself". There is also a saying that tells us, "Do what you do best ,and leave the rest to others." Time has also taught me the importance of another saying, "Do what you think is best." This submission i am presenting is based on preferences I have developed since I built my first piece of audio gear back in 1955 . Back then you could build just about everything in the audio chain yourself. Technology is just a bit more complicated in this day and age, but nevertheless, I feel the possibility still exists to build what you cannot buy, at least in the field of loudspeakers. The following system concepts are those I adhered to when i decided to start this project . Now to begin.-- Restraints of size, cost , or time would not enter into the equation. The room should always comes first, and mine did. Determine the size room you want, and design it along sound acoustic principles. Electronics; Having owned solid state amps for 20 years, along with the power requirements of the system i had in mind , there was no other choice . Solid state ,discrete topology, pure Class A analogue design throughout the entire audio chain. Crossovers; electronic crossovers were employed throughout due to the flexibility needed in designing and building a loudspeaker system that might sail into uncharted waters. All 7 channels would be bass restricted below 60 hz, via the processor , with the subs handling everything below. Electronic equalization; multichannel parametrics operating below 300 hz would be employed on all 8 channels to augment the reduction or elimination of low frequency room resonances not fully addressed by the use of acoustic panels , traps, and diffusers. Loudspeaker design; 3 front towers, identical 9 ft - 4 inch line sources in a horizontal D'Appolito array, four side and rear surround towers, 7 ft- 4 inch line sources in left and right mirror image configuration. Drivers; 15 inch metal cone -high excursion drivers for the subs. Front channels; 7 inch kevlar cone dynamics for mid bass, planar dipole for the midrange, leaf tweeters for the dipole highs. Surround towers; 8 inch kevlar cone drivers for the mid bass, 5 1/2 kevlar cones for the midrange, Revelator domes for the highs. All dynamic drivers, except for the subs, sourced from the same manufacturer to maintain a coherent sonic sign, ature. Drivers and electronics identical to the four surround towers would be in place when processing becomes available for the rear center channel, an 8.1 system configuration. All the dynamic drivers within the system to be in their own separate, sealed enclosures. Baffles for all the dynamic drivers, except the subs , to be either 1 1/2 or 2 inch thick high gloss, black, cast polymer. [ The amount of time I logged from start to finish for construction of the loudspeakers only, amounted to a bit over 5400 man hours spread over 3 years of time. ] Interconnects; XLR type balanced cables used exclusively from the processor through to the 12 stereo amplifiers that are used to drive the 7.1 system; after all, balanced interconnects are what's used to record everything we listen to. Fine tuning of acoustic treatment and and installation of the decorative woodwork trim in the room would be performed after ETF measurements were taken when the complete system was in place , and up and running. At this point in time, both the trim and acoustic treatment are being completed. Upgrades; The 135 inch, widescreen formatted, Stewart electroscreen is to be replaced with a 155 inch, letterbox formatted, Microperf with side electromasking. The Sanyo PLV 70 will then be replaced with a Runco or Vidikron projector with the Cinewide and Autoscope lens features. The last upgrade will be more enjoyment and less work.

Hi Aram,

Thank you for noticing the rugs, they are beautiful, but not Persian.

When I laid out the room , I intended to use oriental rugs, not only for their estethic contribution to the decor of the room, but also because of the acoustical properties they possess. We have a friend who is a 5th generation rug merchant. He supplied us with the rugs throughout our home, some of which, are Persian. We always chose rugs from showroom stock, but soon realized that when we wanted specific sizes, colors and patterns, they could be supplied in authentic Persian patterns and colors, but had to come from India. It seems that, in the arena of oriental rugs, India has benefitted from the turmoil in Iran etc.

We chose from Persian designs, made with New Zeeland wool, to the sizes we specified. The rugs under the 3 front channels incorporate the same design but with reverse and contrasting colors in the fields and borders. While we had to wait 3 years for those to be delivered, we waited over 4 1/2 years for the large frontal rug. That rug, made with a 310 line knot count , took 2 crews of 7 people each, working 10 hour shifts per day, 7 days a week, for 19 months, to weave; so we were told. It was almost a 3 year wait for a loom large enough to become available before the rug was begun, the result was worth the wait.

One additional benefit of having wool rugs is that they don't have a deliterious effect on audio cables as do synthetic fiber rugs; so say the golden ears, of which I am not one.

Building a room that is acoustically correct doesn't always have to incorporate things that enhance the audio performance, but only look good in the dark. I intend not to follow that scenario.

thanks Ken.

WOWWW..Look at the quality of the carpets..Are they real Persian mate?

Kha,

I finally got to the Barco web site. I guess that I won the lottery and just didn't know it because that is the only way I could afford that fantastic projector. They were designed for Metroplexes to replace film projectors.

Last year I saw the $30,000 Sony Quallia projector at Home Media here in Richmond. There was and still is nothing like it. The problem was that the ANSI lumen output was too low to work in a dimly lit room, which is how Sue and I like to view movies.

My brother just bought the new Sony projector using the SXRD panel , less than $4500. and NO SCREEN DOOR EFFECT. It may only be a matter of time before Sony escalates that technology to the level that I can use. We have the Sony 60 inch SXRD in another room and the picture is better than anything out there. It is able to present images that the present media is unable to provide.

Think about the old adage---"I just met a woman who is rich, over sexed , and owns a liquor store," but in my case, I'm too young to drink. I'm hoping that in a year or so, when the technology progresses, I'll be able to purchase that LAST video projector I'll ever need. YEAH right !!

We have a beautiful audio video set -up but the majority of our enjoyment comes from 2 channel audio, especially on the nights we set aside for ourselves. Good dance music, a big dance floor, no shoes or much of anything else, but fun until we are too tired to keep it going.

Karl, getting on the subject of vinyl, arms, etc; I know you have 2 Kuzma Air Lines, and cartridges galore, I hope I may presume to call on you when I finally get my arms and cartridges up and running. There are few "gonners' that have the gear and knowledge to get the most from what they have. I trust you will impart your experience to a fellow "gonner" that hasn't had vinyl spinning for many years.

thanks, Ken

Kha ,

You have me at a disadvantage, I have no idea what the DP100 system is.

I have 158 inches between the left and right speakers. My present screen is 20 inches less. I cannot use a widescreen formated screen without increasing the vertical dimension that would make me bug eyed. Having all format pictures the same height and adjusting only the width is apealing to me.

I will check the Barco web site but I feel you have an opinion that a salesman wouldn't have. Please enlighten me, and thanks.

regards, Ken

Hi Ken,

quite ok but change your beamer to the DP100 Barco System.
It will match your speaker´s setup.

Hey Bulldogger,

You're right,fantastic audio is the perfect venue for great video. When I first started building the room, the idea was for 2 channel audio only; I started the room about17 years ago. When the plan changed to accommodate video the first screen I installed was a 135 inch Stewart techscreen micro-perf formatted for an ntsc image. This screen was later replaced with the same series screen only formatted for widescreen.

At the last cedia show I saw a Screen Research spun woven acoustically transparent screen that is nothing short of spectacular. If that screen would have been available in a side electromasked, letterbox formatted, electroscreen in a 152 size, it would be in the front of my room along with a Runco projector fitted with their auto lens feature. As of now a RETRACTABLE screen is unavailable with those features in that size. When one is it will be the next upgrade for my system.

While the system is portrayed as a 7.1 system, 90% of its use is for 2 channel or multi channel audio using the SACD format. However, the impact it delivers on video; Master and Commanderand other blockbusters is nothing short of spectacular. As Blu Ray and HD DVD begin to take hold, the addition of movies in hi def will have me licking my chops.

Now all you need is a HUGE acoustically transparent screen across the front to match the audio. http://www.smxscreen.com/

Hi Rehan,

There are times when I think my address should be a sanitoriom, my wife thinks that now. It's great to build whatever you want without any restrictions, that certainly has been my circumstance. It took 5400 man hours over 2 1/2 years to build the loudspeakers that underpin my system. The way they sound was worth the effort.

I recognise the BG tweeters you use in your line arrays. Igor Levitsky , who designs the drivers for BG was very helpful when I was designing and building my speakers. It was fun to finally meet him at the 2005 CES after the many times we talked on the phone . I know your system incorporates some of the finest drivers money can buy. I can't help but think you have your eye on something bigger.

I'm in Richmond Va. If you ever come my way, just email and we can set up some time to clear out a few cobwebs from our ear canals.

regards, Ken Fritz

hi, you make me look quite sane. where is this system.... I have to meet you in person to give you the official honor of being the crazziest audiophile....person alive.

Hi Jlambrick,

Thanks for the reply. The system does presint a soundstage unlike anything I've heard. The 9ft 4 inch line arrays along with the 26,000 cubic foot room I designed and built for this type of a system work beautifully together. As you might imagine, the speakers and the room they play in must exhibit good synergy or all will be lost.

I'm located in Richmond, Va. If you're ever in the area, you're welcome to come by for a listen, just email me and we'll set up a time.

regards, Ken Fritz

kftool

Wow, if this doesn't qualify as all-out-assault I don't know what would. I would LOVE to hear a system of this magnitude. This is probably about as close to a holodeck as current technology permits. I'll just have to imagine.

Bryan, I assume that when you say; "I am definitely going to put together an office system with nice monitors," you mean computer screens for your new office staff to monitor your new accounts. Just kidding, as I know what too much exhuberance can do. When I bought out the "Alligators" who were my last partners, I went out and bought 5 computer terminals to bring my company up to speed; 2 years later I sold them for 10 cents on the dollar, unopened. I knew then, that only hard work will get results.

I'm sure you know, the last comments were made in jest, I know
you'll do what it takes to finance the next audio upgrade.

I'm working on a new posting that will encompass many of the shots I took over the 2 -1/2 years it took to build the speakers. Most of the postings on Audiogon show shots of commercially available products. I hope to include shots that might otherwise seem to have been taken at a speaker manufacturing plant. 4 months ago I registered a domain name for a dedicated web site for the project. Time has not been on my side as I have done nothing but paying the bill for the web site. Maybe things will change and I will find time to compleat a project that has caused my wife, Saint Mary, to call me extreme. thanks Ken

kftool

Ken,

Sounds like you have a great plan ahead of you. If I'm ever in Virginia, I'll bring the steaks and seafood, and you can provide the entertainment. I would be interested to see new pictures. These on the website, have been up here for a while now. I imagine there is plenty of undocumented progress.

I went and visited the owner whose practice I am working to acquire. It's about 600 sq feet only, but the office is open with no employees and rare visits from customers as the owner makes house calls mostly. I am definitely going to put together an office system with nice monitors and a 100 wpc aluminum. There's alot of great used amps in this size that are very reasonably priced.

I know you are busy, so I will keep checking back for updates periodically.

Hi Bryan, It's Sunday now, I've been away for a few days and just read your posting. I hope the meeting regarding your business purchase went well, and you are now another over taxes and over regulated business man.

There area few changes to the system in the works. In a few months Krell should be delivering their Evolution 8.4 processor. When I was building my speakers I called Krell to see if the next generation processor would support a rear center channel. When they said it wouild I purchased the same driver complement as I was using for the 4 rear and side surrounds along with the Krell KBX 3 way crossover and associated Krell amps for the rear center skpeaker that would be required some time in the future. It looks as though the future is now, so I've started building the cabinet. It will be a full horizontal D'appolito array and be mounted 7 feet from the floor. I hope it works out.

While I still don't have my SOTA Milennium-Tri Plainer- Shelter 90X together and playing, I've decided to build a table; vacuum platter, double motor-flywheel drive, cast polymer base etc. I plan on using 2 tonearms on the table; a Dynavector DV507 MK II which I picked up here on Audiogon. Twenty years or so ago, I had a chance for a Dynavector 505 arm, and waited too long in deciding to buy it. When the opportunity passed I regreated not acting faster and figured there would be another time. A new 507 MK II came up a month ago in the U.K. at a great price, I didn't hesitate this time. The build quality is fantastic. While it is a nostalgic purchase, it won't be my main arm.

I had been reading all I could find on linear trackers and pretty much decided on one. It appeared that until Andy Payer comes out with his Sirius Series 5 table, I guess I missed the Series 4, the Kuzma Air Line seemed to be at the top lf the heap. I spoke with another Audiogoner who was in the threads on Kuzma. After that discussion, I ordered it, and should have it in another week or so. Now I need to get started on the tooling for the cast base. I'm experimenting with a variety of fillers for the matrix. I'll be using 200 lbs of #6 lead shot along with other materials, It will be a fun project.

I had my Ampex 351-2 shipped back to me from Milwaukee 2 months ago. I bought it new in 1958, used it for 4 years, sold it to a friend of mine who never used it, and bought it back from him this last Christmas.. It is gorgeous and doesn't have a scratch on it.

I need to edit my posting and show better pictures than those I have up there now. There never seems to be enough time to get it all done.

Thanks for the reply and please keep in touch. Now that you have your own business, I can see you're already thinking about your next system upgrade. Ken

Hey Ken,

Just thought I would drop you a line to see what is new. I'm meeting on Saturday morning with the owner looking to sell a CPA practice in the suburbs here. I think your advice above is solid.

Any new changes to the system? I would be interested to see new pics of your system or hear about any new equipment purchases.

Hi Bryan, you're heading in the right direction; being in business for yourself is great , especially when the rewards or dissapointments for your personal capabalities are shared with a woman who realizis that you, as an audiophile, need a new toy when he, "Does good", as they say in the south.

The Richmond Audiophile Society refers to my wife as "Saint Mary". It would be hard to enjoy this hobby if my wife didn't realize the satisfaction I get from every facet of music and the means it takes to realize that enjoyment. As time goes on I'm sure you will realize the importance of having a wife that recognizises the importance, not of only the monetary rewards, but the feeling of being able to enjoy the thrill of the musical experience that escalates along with your ability to upgrade that "old stuff', you've had for years. When she sneaks in a new pair of shoes; I feel confident that, you as an accountant, can materialize a Krell, which you've had around for ages but forgot about, that will convert her to the Audiogon camp. If not, at least it was worth a try. regards, Ken

Please keepin touch, and good luck, best regards, Ken

Hey Ken,

The trip to China was good, although I never ran into any high end audio shops, so I'm not sure where they are making or selling these products. I recently married and am saving my money to buy an Acctg firm...hopefully that will occur this year so I can be in business for myself. The only way to be more than comfortable is to be the owner, right? I am looking at Krell 2 channel pre-amps on the classifieds, but I really need to save my pennies at the moment. Every once in a while when I'm listening to a live album or a really powerful rock album, I wonder what it would sound like on speakers as large as yours. I still think your speakers are the best I've seen on this page or any other. If something isn't made the way you think it should be, do it yourself. That is the best way to go.

Hi Bryan, priorities seem to change as the weather gets warmer. I never seem to be able to finish one outdoor project before another pops up.

There are a few system changes in the works; Krell is about to release the new Evolution 8.4 processor they've been working on. Two years ago they said their next generation processor would support a rear center channel so I purchased all the drivers, active xovers and amps to facilitate construction of that speaker. I'm building the pattern for the mold for the cast polymer baffle I'll need to produce.

The acoustic treatment panels I had Acoustics First build for me, they've been in the crate for a year now, will be installed soon, as I'm now starting the woodwork trim for the music room. I generally only work on the room on rainy days.

Although my Sota Mellennium, Tri-Plainer, Shelter 90X has been sitting for almost a year, not yet set up and running, I wanted to look into getting a second table, with a straight line arm. I considered looking at a Walker, but it isn't a vacuum table, a feature I like. I decided to assemble a table with the features that are important to me. The direction I've chosen will be unique and fun to build.

Bryan, with all the fun stuff going on it would be nice to be retired and play all the time. I'm hoping that time will come in a few short years.

How about your system; any thoughts on pending upgrades or changes? Did you see anything interesting on your trip to China? The articles in "Voice Coil' magazine continue to make greater references to all the high end manufacturers now not only sourcing drivers in China, but also having a good portion of the lower end of their lines completely produced there.

As always, I look forward to your responses and hope your ears are well. ken

Hello Ken,

I have not had the opportunity to check out any audio equipment. From what I have seen, most of the goods sold here in Shanghai are copies of American clothing, watches, dvd's, etc. I will delve into learning about constructing my own speakers. To me, the world of high end audio is thinking outside the box and exploring what else is out there. What you have done with your system is taking that independent thought to the next level for sure.

2-18-06 firecracker-77. Bryan, I hope you'll have some time to check out some of the Chinese audio brands we're seeing on the American scene
There have been a few references in the replies listed on my posting regarding how one goes about acquiring the information to build a properly designed loudspeaker. It's certainly more involved than just assembling drivers.
There is a forum for those who are interested in getting "just the facts", without assimilating the comments made by reviewers offering their opinions on their listening experiences. Old Colony Sound in Peterborough, NH has long been a source for straight forward technical information on drivers , enclosure designs, crossover types and designs etc. They are available in book form and written by the industry icons who have determined and laid down the physical constants that define the parameters on how loudspeakers work. Some of the books are written in a way that require a firm grasp of higher level mathematics. Others are presented in a way that make it possible for someone with an average education to understand and apply the basic principles of how loudspeakers work to assemble a reasonable good system. This information can be viewed at www.audioxpress.com. Back issues of Speaker Builder magazine, now AudioXpress, contain articles written by audio enthusiasts who took the plunge and invested in their ideas by building a loudspeaker system. Sometimes just reading about the attempts of others can cultivate the creative abilities in the rest of us.
Another wealth of readily available knowledge comes from the many companies that supply drivers, computer designed crossovers, cabinets and other items needed when one sets out to build their own speakers. Those that work at Madisound, Meniscus, and the other industry suppliers listed in AudioXpress, in many cases are super speakerphiles that are more than willing to impart their experience to a new speaker builder.
Last, but not least and maybe even foremost, are the written reviews of the golden ears in the press that have the envious ability to make a phone call or two and have some of the most exotic, expensive and desirable loudspeakers delivered to their doors for reviewing, without ever writing a check. The rest of us should be so lucky. Reading and assimilating their opinions , along with the published technical data available on speakers , was enough impetus for me to start building my own designs many years ago. It might also be enough for you to take the plunge, try it, it's great fun. Ken Fritz--kftool

kftool

Kftool,

I am in Shanghai at the moment, but will check out the website you refer to when I get back home. At the very least, I can read about my options instead of having to continue to purchase speakers from manufacturers. It's good to think outside of the box especially when large dollars are involved.

Rob, Your comment was on the mark. I've never been able to say as much, using so few words, as you have. The dedication has always been there, with the resources arriving much later. At some point in time, perseverance crept in to keep the dedication rolling. Long term goals are great, and better appreciated, when they're finally realized. Thanks, Ken
