Looking at the specs it says it plays down to 18Hz.

I know to some times take these kind of things with a grain of salt but I think definitive technology is a respected brand name.

I love Def Tech, have had Def Tech speakers for a very, very long time but I personally wouldn't go with a sub from them. Too many ID companies, cheaper with better choices. I mean I wouldn't say it's the worst idea but I think there are better choices out there. I have an all Def Tech system except the sub which is an SVS PB-1000. Love it.

DefTech is (in)famous for being fairly liberal with their stated frequency response stats. Without knowing how many db it's down at 18hz that spec is essentially worthless. A sub that can hit 18hz flat or only down 3db is damn impressive. A sub that's down 20db at 18hz might as well not say it hits 18hz because you'll never hear it.

I'm going to agree with both of the previous posts. My first sub was a small DefTech and I know that the specs were inflated. In this case, a 10" woofer with a 300 watt amp, in a small cabinet, doesn't have a hope of hitting 18Hz in a meaningful way. I would look at Outlaw or SVS for better subs in a comparable price range. You definitely want something that will get down to about 20Hz reliably, and I don't believe that the DefTech sub will come very close to that.

Regards,
Mike

Anything can play down to 18hz but if you can't hear it, it's pointless. That's why if a frequency response does not have a loudness range, I normally ignore it. There is a huge difference between 18hz-150hz +-10db vs 20hz-140hz +-3db.

For that price I'd say it's not bad. I currently have that exact sub and only recently upgraded. It's a great little sub so long as the conditions are right (small room, corners are available, etc).

I'm sure it does, at levels too low to hear.

After reading a bunch of reviews I wouldn't say it's a bad sub to buy. If you had your heart set on it I would go for it. I would still check out others but I did read a bunch of good reviews on this sub.

My first sub was a DefTech (12" driver, 250W amp) that was rated to 18Hz +/- ??dB. I asked the company for the FR with a +/-3dB variance. Turns out 18Hz was actually 26Hz.

Run as fast as you can. If you have a Fry's nearby you can score the Klipsch R-112SW for 300.00. Be a much better buy imo. Or grab a SVS PB-1000 outlet for 449.00.

See if you can pickup a used Sunfire and then have Frank at carversunfire@gmail.com do a rebuild for you. Just got mine back and it sounds fantastic! I have it paired with a pair of Klipsch Heresy's I recapped and installed new tweeters from www.ctitesspeakers.com. All in for less than a grand.
