Beautiful sound, deep hits, great sub

I have two of these subs in my car. Just a regular type 1 sealed box and a capped 800wrms amp. these subs sound wonderful. They are sensitive enough to give good response at low volume, and burly enough to really pound like hell when you turn it up. I had them facing into my back seat and I could watch the back seat move a good inch back and forth. The best part of this sub is the frequency range, all the way down to 18Hz, and you can really tell. I heard notes in songs I've never heard with other subs. I love these subs. Pounding hard for over a year with no problems.

WOW!!!

I just bought 2 of these subs from techronics.com (don't buy from there, they take forever to ship your stuff. same price here anyway.) I just hooked them up and am in the process of breaking them in, and they are already pounding incredibly hard, and i only have my amp 1/4 of the way up. They are very loud with incredible quality. I recommend these to anyone who is looking for that perfect mix of SPL and quality. After they get broke in, I will update this review and let you know what I think.

WEAK CONE STRUCTURE

THIS SUB DOES PERFORM WELL BUT IT HAS A WEAK CONE DESIGN IT'S NOT STRONG ENOUGH TO TAKE ALL 350 WATTS, AFTER USE AND BREAKING THEM IN WHEN PUT IN THE PROPER ENCLOSURE THESE SUBS WILL BAFFLE ON HIGH POWER APPLICATIONS (700WATTS)SO PLEASE BE CAREFUL WHEN USING THESE SUBS AT THE POWER LEVEL THEY SAY THEY CAN TAKE RMS. 600 WATTS WOULD BE SUFFICENT ENOGH TO MAKE THESE SUBS PERFORM AT THEIR BEST. OH YEAH THEY DO PRODUCE LOW NOTES VERY WELL
