Description


After 20+ years with Avanrgarde Duos I made th eswitch to Voxativ field coils. The Duos were and still are superb. The FC are slightly more cohesive and smoother and I might have just been itching to change. Could happily live with either

I am guessing your passive xover lacked time-alignment? With bass horns of your size I would guess that issue alone would put the digital XO firmly in the lead.

That said, nothing at all wrong with the digital soln! I am doing it too! I guess there is some part of me that still isn't quite on-board yet.

Herman,

I would love to hear more about your vinyl digitizing: in your experience are the results as good as the vinyl? Are you doing 24/96? My experiments doing same at 24/96 with a rather humble Masterlink device were very encouraging. However, the vinyl was still noticeably better so I stopped.

My system is now Orphean bass bins with the Ah! 300 horns. With EQ, no real need for tweets. I am now using a DEQX and it is very promising, though not yet optimized. No digital sound signature whatsoever.

Did you experiment with passive xovers at all?

If I had room for bass horns, I'd do it. Yours look great and must sound incredible.

Perhaps I will try Edgar bass bins or some similar ~80 Hz horn with subs underneath some time.

Herman, I have been eyeing your setup for some time. (And we have talked of course.)

I'm finally taking the plunge into front horns with an Ah! 300 horn with B&C drivers couple to Orphean Reference bass bins.

I plan to use a DXC2496 to cross.
