>actually i never look into the SVS subs, but after going over thier website, lookin at pictures and spec . . . wow. . .i might be more inclined to buy an svs vs. velodyne. but then theres the ELF subs from Bag End to consider too.
I went through the sub search a few months back. Here's what I learned on the sub forum (gross paraphrase for brevity).
If you are going to spend $300, don't bother, stick with the cheap $150 dayton. $400 or so is the differentiation point where quality improves dramatically. Around $700-800 it improves again. My budget was stuck around the $400 point. At that price point there are only 3 subs worth the money- SVS $400 or so offering, HSU $400 or so offering, and the Mirage S-12, $800 but marked down at Vanns.com for $400. At $800 it was overpriced, at $400 it was a steal. All perform basically the same, with their own pros and cons that aren't much different from each other. Search the sub forum and you can find all that info. I went with the Mirage, because the HSU was like $450 or something, and the SVS was on backorder. I've had the Mirage for 3 months now, and love it. I have Polk rti12's, csi3 center, rti4 rears, and my open floor plan ends up being about 3600 cubic feet. I run the Mirage 10 db hot (compared to calibrated levels) and only at 50% power. When I'm playing around and I turn the knob all the way up, it's overpowering. Check out the sub forum, you'll see the same info I just told you.
