Hey TBers! I just picked up a moog low pass filter and I love it. Its capable of producing the very loooowest frequencies and it got me thinking about subs. Right now I have a DB680 and a PLX2402 I use with Berg HT210/115 cabs. My first question is about power amps. Ive thought a lot about getting a Crest CA type amp. My thoughts on a setup are to use one amp to power the Bergs full range and another to drive a sub with the low output of the DB680 crossover. Which amp for which job? Would you choose something other than CA and PLX? My second question is about subs. Which ones do you like?
