Soundhound,
I don't need a bigger house. I just need to toss out the guest (queen size) bed that we keep down there for the in-laws.
I started to play around with the sub and found out that you were right. No, not about the stereo sub, but remember the power supply and output upgrade on Adcom GFA 555 II. You recommended against modifying it. I did and it is not enough to drive the sub. Heck, when I switched to CJ MF-200 which should have less power, the sub came alive (to an extent).
So, I just ordered a Crown K2 amp thinking that it should be enough to drive 2 of these subwoofers when(if) I get a second one. This pro amp comes with xlr and 1/4" input. My Marchand X-over only has RCA out. Where can I get an adoptor?
