I have read so much about these subs. A speaker-builder friend of mine says these are the best kept secret around. I think I will buy one, probally the 16 or 20 version, no amp. I have a Rotel 981 bridged puts out over 350 @ 8ohms. I not affraid to run this amp under 8 bridged especially with the limited bandwidth. I have ran a pair of 2ohm speakers for hours on end without any signifant heat or audible problems. My question is What do you who know of such things think about this set-up. I love HT (and music) and I cannot live with distortion, I want good tight, accurate bass. I have 4 tens that I use now, built by my SB friend that are the best sounding subs I have ever heard, but, they dont go below 40hz period. You can boost the bottom and all you get is 40hz and push the amp harder. I have lived with this for 2 years now only because they do sound that good, most of the time they are fine but occasionaly I do like to scare the old woman by rattling the broiler pan in the oven among other things. I have listened to the Paridigm Servo 15 and IMO it is OK. I dont expect a $500 woofer to outdo the Servo 15 . . .or do I?
