About 5 months ago i purchased a B&W asw600 sub (10inch driver 150w amp), along with 602s3s, lcr60s3, and 600s3's. Everything is fine except the sub. Well not exactly, the sub performs well, but does not go low enough nor does it have the punch in the stomach that I desire for HT. In addition it seems to have a faint rattle during heavy scenes.
Increasingly I am thinking of using my 1 year trade in at my shop, the subwoofer brands they carry are B&W, Velodyne, Definitive technology, Klipsch, and M&K. What I am looking for is a sub that will give me the punch that we all love for HT. What I am worried about is replacing a very solid, extremely well made sub that sounds extremely good in most cases with a sub of poor quality that just spits out noise.
My question is has anyone had any similar experiences with B&W subs versus the above mentioned other brands?
BTW I paid 450 +tax for the B&W and am looking to pay up to 7-800 for a new sub.
Thanks in advance.
