Help with this sub woofer.

I'm thinking about one of these, I don't know anything about them, but the idea of a 60$ 18" sub is pretty cool.

Anyway, if anyone here knows the spec on this sub that would be great //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif or if it would even be a good choice for a new HT sub at all.

EDIT: lol I should probably show you what it is.

That is a midbass driver.

For real? An 18" midbass driver?

Yepp. Sure is. You need 4 of them and super custom door pods //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Haha right.

Anyway, a straight answer would be great.

Looks like CTS doesn't manufacture for retail sales..

Yeah, that's PA gear from waaaay back. Even if the Fs is truly that low and it were to serve as a subwoofer (and it could), the required enclosure would be very large. In all likelihood it will be huge. Like, impractical-for-use-in-most-vehicles-and-rooms huge.

Skip it, son.

square magnet. amazing

like the dude in the add said - go infinate baffle with it in a closet or something. for 50$ each id buy the pair. not 60 tho.

I bet they can also play a range of hz. probly rated from 40s to the 2k regon id guess

DON'T even think about it. I have an old tube guitar amp with a Celestron 18" speaker similar to these CTS's. They are designed to run in the 30hz - 4K range. They have a pronounced "honk" to them from the mid-bass range. Perfect for guitar, but not good for subwoofers. You would have to tune way low and it would probably be better in a bandpass to kill some of the mids/highs.

Super high efficiency is usually a good indication of a pro-audio type driver and not a subwoofer. Notice that most true subs have efficiencies in the 80s or maybe low 90s for an 18. Efficiency in the high 90s usually means a very low Fs thanks to a very light Mms. Those are indeed PA mids meant to keep up with a horn loaded mid/tweeter with an efficiency somewhere north of 100dB/w.

Could make a killer 2-way with those in your house. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
