I got my SVS sub yesterday and hooked it all up last night. I used the AVRs test tones to set the volumn and everything seems to be adjusted right. Ran thru the Avia disk and all sounds fine. Put in a few DVDs and not that impressed. Tried Pearl Harbor, Vertical Limits, Braveheart, then music Steely Dan, Eagles, Sting. I was expecting a nite & day difference between the JBL PB10 and the SVS but it's not there. It sounds better but I'm not doing back flips and talking about structural damage yet.
