Anybody heard this sub before? Its a 12" woofer I was reading about the other day in Car Audio and Electronics. so I decided to go online to see if I could find a retailer around here to maybe listen to it. No such luck. Any info would be appreciated. The article stated it had a 94dB sensitivity rating.

I've heard that it was a good line, but it doesn't look like there's a distributor in the USA.  Here is contact info. 

When I see a very high sensitivity like that in a car audio 12" subwoofer, I get a bit suspicious and do a little research and math to verify the efficiency.  You should read DYohn's featured article, Loudspeaker sensitivity vs. efficiency to find out why I'm pointing this out to you.  Here are the specs of that particular sub, and this is the calculator I used to find the efficiency.  It appears to be equivalent to 88.5 db sensitivity, which is not at all bad in the realm of car audio subwoofers.

If you're comparing subs like this (and it's a good idea to include this factor along with all the other factors), you should verify efficiency with every one of your prospects.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Thanks for the reply Steve! I was wondering to about a US distrobution too, but the strange thing is it was in a US CA&E subwoofer buyers guide. Anyways Im planning on doing alot of research on this sub later on tonite and Ill post anything I find regarding specs, us distro. etc for anyone interested.
