Here is a high grade floor standing speaker designed by Tony Gee of Humble Homemade HiFi. It’s based on Accuton C30-6-358 cell tweeter, 173-6-191E woofer, and 2 P173 passive radiators.
My cabinet differs slightly but the internal volume etc. is to original specifications. It is a translaminated construction of baltic birch plywood. I had the pieces cut with a CNC machine. The front baffle is 1” baltic birch epoxy laminated with a .25” sheet of aluminum. There is extensive interior cabinet bracing with a separate sealed compartment at the base for the crossover.
The cabinet is lined with .5” of felt and sheep wool stuffing.
The crossover was designed and modified after listening sessions over a year. I purchased the designed and assembled crossover from Humble Homemade HiFi.
Dimensions: 45"h x 10"w x 12"d
$1850.00 plus shipping. The speakers are located in Phoenix, Az
