The prototype Stereo Integrity BM subwoofer has arrived for prototype testing. It is a very nice driver and the basket is VERY nice. The integrated cooling should help power handling a TON. Expect some results up later this week. Yes ladies and gents i got a SQ driver to review //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Basket haters! *laughs*

I like the basket... but the fact of the matter is Nick didn't pick it for looks; he is using it since it has more mechanical clearance than a 12-spoke, offers better cooling, and allows the use of the carefully placed lead wires due to the taller clearance -- they won't slap until you exceed linear x-max by a substantial level. The higher clearance also allows for the removal of the triple joint and the creation of two separate joints to spread out the load a bit.

For that matter... it actually does look alot better when you have it in front of you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I personally did 2 hours of thermal testing on this little guy as well, and it passed with flying colors playing sine wave material for the entirety. Of course, the neatest thing about this driver is that it doesn't require a boat load of power to reach high x-max levels. It is also one of the smoothest sounding woofers I've ever personally listened to as Nick and myself auditioned it in my Civic with a mere 200 watts.

Low-end extension is stellar sealed... ported it would be a little beast, although Nick and I did not test that alignment yet -- Chad will likely do so //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
The motor looks SEXY though.
aside from the mismatched front and back plates....
The finish on the plates was not a consideration for prototyping //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Don't worry, it will be taken care of for production.
