The T3 Audio TSS is a musical woofer with a rating of 1000 watts RMS..... lots of excursion.... but designed to be loud on low power with nice sound thanks to low moving mass. The TSSV2 is the spl woofer and is more comparible to the "nightshade". And the TSNS will knockdown anything you compare it to. As far as Jason goes..... according to Bestco (your reps)....85% of all T3 Product returned has been by you at M&M. Loud by design guy managed to blow up the TSS woofer in record time (10 seconds).... so he is definitely doing something right... Keep up the good work...... I think education, appreciation and determination will get people alot farther in SPL competition than just hooking it up and blowing it up and then blaming the speaker. Good luck everyone.
