My experience adding subwoofers to 2 channel

My Kappa 9 speakers are rated to 29hz and they sound pretty good in my 18x24 room...powered by McIntosh mc1.25 amps...l was looking for another layer of bass to enhance the sound..my first experiment l took my SVS pb16 ultras from my theater room and tried them first...it sounded terrible,didn't blend well..couldn't hear a difference until you turned in up then it rattled the room apart........my final experiment worked..l used 4 Velodyne minivee subwoofers(1000 watt rms class D sealed 8 in.) and after hours of calibration l hit it......lve got the bass response that exeeded my expectations. ....l should have done this along time ago....can anybody tell me of another subwoofer that may work even better?

Clio for $12,000 as listed on Roger’s web site does that include the amps? Why doesn’t he put a page up for the speakers and all the other neat stuff he makes like the 300 watt mono amps?

Atmasphere, those amps got damn hot. They were also easy to over drive if you did not cross to a sub. They hated doing bass. The best sound I got out of unmodded Acoustats was 2 + 2s driven by KMA 100s. They even did bass! I got rid of Acoustat’s interface and hooked up one huge 1:100 Sowter transformer which is crazy to drive but boy do they sound great. Yes, Soundlab owners love your amps. The question is should I do MA-2s or MA-3s:)

@mijostyn, yes that includes the direct drive amps and bass amp with active crossover. As for why it's not on the website the main reason that Roger doesn't have the time to bother with it.

@clio09, are you sure the $12,000 price is with the d-d amps? I stated that a few months ago in another thread, and you informed me that was incorrect, the $12k was for the panels and subs, the d-d amps were an added-cost option. If the price includes the amps, that is quite the bargain!

@bdp, thanks for pointing that out and sorry the mistake. The DD amps are extra. If purchased without the DD amps a separate power supply for the panels is included for use with other amplifiers.

Are the DD amps designed after the Acoustat amps. How tall and wide are the ESLs. Single flat panel? Does he use them himself?
