Sub or Subs to mate with Sonus Faber Amati Homage

What amps are you using? (or have used, since you said your have tried several)
I really think that might be the problem. Are you using tube amps? (Sometimes tube amps are a little weak on low frequency response.)
I would use either Krell or Levinson amps. (I use the Levinson No. 23 (200W/ch) on my Revel Studios and they are rated about the same as your Amatis are for frequency response, and I get pretty good bass out of them. Not thundering, but then again my room (16'x24') would sound boomy with too much bass.)

I believe that the Amatis go down to about 28 HZ, which really means that subs are probably not needed.

Those are my 2 cents worth anyway. Good luck.

PS I used to have a Velodyne (15") that had pretty good bass. The problem I always had with using subs was getting the crossover point right. Given your speakers, I think this might be problematic for you as well, since your speakers (theoretically anyway) have pretty deep bass response.

I agree with Kurt tank. You pretty much have full range speakers. With the right amp, you should do far better. The problem is finding the right amp. You also might consider switching over to XLR connections throughout to take advantage of the XLR's additional 2volts. These 2volts almost always will provide at least a minimal improvement in macro-dynamics amd bass solidity.

And of course, your room is going to have a tremendous affect on the quality of bass and other aspects. My new room is nothing like my old room. In fact, tonight, I played with speaker placement again and was finally able to obtain perhaps 4/5ths of the bass and overall sound presentation that I had in my previous room (which acoustically was far superior). At least I'm smiling again.

The final placement of my speakers was darn close to the placement recommendations of the program found on Rives audio web-site. Rives advertises on A'gon quite a bit. Thanks Rives.

You did state above that the SF Amati Homage's are extremely difficult to place. I'm not sure why you believe that. I would guess that they should not be too much different from any other full-range speaker weighing under 200 lbs.

I would also recommend your auditioning the Audience Au24 speaker cable. They are a bit amp dependent but with the right amp, they can provide some of the best bass you've ever heard. Even with the wrong amp, your bass may be substantially tighter, but could sound lighter as well. The Au24's are noted for minimizing/eliminating a time smear supposedly found in most other cables.

-IMO
