sundownz Posted July 8, 2008 Author Report Share Posted July 8, 2008 I've always wondered what would happen if a company were to build a 12" woofer with a 6" or more voice coil. Even if the magnet was bigger than the woofer in diameter. Acoupower is making 15" and 18" drivers with 6" coils and an internal neo motor. They are SQ drivers, though The BL^2 / Re is under 100 so they wouldn't make a good burp sub. The biggest problem with a 12" driver and a coil that big is that your spider becomes really small.

sundownz Posted July 8, 2008 Author Report Share Posted July 8, 2008 The cost of copper went up 50 cents per pound cause of that coil..... lol. Damn thats a rather large coil you got there.. *laughs* The coil is actually aluminum - just looks copper w/ the enamel. I am thinking about offering a copper coil, though, for a low-end monster sub - the mass of the copper would take the Fs down REALLY low.

sundownz Posted July 8, 2008 Author Report Share Posted July 8, 2008 5000wrms? maybe datsalotacopper We'll see I am testing some cooling tricks - I'll keep the forums posted when I get some power results.

Forevrbumpn Posted July 8, 2008 Report Share Posted July 8, 2008 Ive tried prototyping subs with them coils before, boy are they hard to solder, crimp or anything!! Also, I refuse to say a 6" VC on 12" sub wouldnt work due to spider excursion I have used subwoofer surrounds to make spiders, and works fine ^^ no spiders at all in this subwoofer at all just a high excursion 12" cone/surround, and 10" cone of same this thing never bottomed out, and theoretically, the surround/spider was only 1" wide from coil to mounting area so its definitly doeable But nice sub in the makings there Quote I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

sundownz Posted July 8, 2008 Author Report Share Posted July 8, 2008 (edited) Pioneer uses a system like that - I question how linear the Cms is without some serious R&D like Pioneer has in it. IMO, a 6" coil on a 12" sub just isn't useful (without a depth constraint) - by the time you have that much power handling on it you either have a suspension that is too tight and you are wasting most of the power and/or you have ran out of excursion anyway with a softer suspension. Now, for a shallow driver a wide coil is fairly useful to get more surface area from a tiny winding height - but they don't have much excursion anyway - eg: the JL shallow driver and the Morel Ultimo (5.1"). IMO anyway Edited July 8, 2008 by sundownz Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected] Link to comment Share on other sites More sharing options...

sundownz Posted July 8, 2008 Author Report Share Posted July 8, 2008 That kinda look like one of those XBL^2 motors Nah, it just has a really thick top plate and back plate - there isn't any XBL^2 going on inside.
