Although I generally find it distasteful to name products in head to head comparisons, I'll make an exception in the case of subs simply because I've spent good money on what I've learned to be unconscionably poor sub-woofers.
I owned a Definitive Technology sub for many years (about 13) and I always thought the bass was kinda unrefined, hollow and somewhat flabby. I also felt it had limited extension and volume. I figured 1000 dollars was about all I could spend and that Def Tech must be providing a decent value for money product, as they had been doing with their bipolar towers.
About two years ago, visitors accidentally sent a rocking chair leg through this sub. Now I could've replaced the driver, no doubt, but why when i was mostly dissatisfied with this design. Instead, I went to Circuit City and bought a "brand name" sub-woofer (Velodyne). Granted it was a low end model (VRP-1200), but hey, this is Velodyne, right? Would they put their name on a poor performing product. I got the thing home and basically heard no better, and perhaps worse performance from it, than from the Def Tech.
Ok, now I'm really curious...What's up with these subs? So at that point I'd read several positive comments on SVS products, researched it more, found nothing but praise for them, and settled on trying a 25-31PC+ with the new 12.3 woofer.
I got that monstrous looking thing delivered and set up, turned it on, cranked it up and my tongue and jaw dropped to the floor while my grin stretched from ear to ear :bigsmile:
Thanks to SVS for teaching me that < $1000 subs from other manufacturers should instead be called "NOISE MAKERS" cause in my limited experience I've come to conclude that, with SVS being an exception, that's exactly what they are.
