enhanced250 Posted July 28, 2011 Share Posted July 28, 2011 Anyone make their own box for a sub 12 and amp? I was just wondering if there was some improvement that could be made. Quote Link to comment Share on other sites More sharing options...
MikeFord Posted July 29, 2011 Share Posted July 29, 2011 Building a sub is an excellent first speaker DIY project, its a box with a hole, nothing simpler, except maybe a tube with end plates. Improvements are more a question of what you want, ability to customize the design, but I suspect you don't have to go far down the road to improve on building quality just by using better materials, heavier panels, more bracing etc. than is practical in a consumer product.

enhanced250 Posted July 29, 2011 Author Share Posted July 29, 2011 Yea that's what I figured. I come from a background in car audio fabrication so building it is not an issue. I was wondering if anyone had some tried and true design plans for the sub-12. Ported vs sealed size etc. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 29, 2011 Share Posted July 29, 2011 In order to build a Sub-12 clone you'll need a Klipsch driver and amp. I doubt you'll do a better job at design than the Klipsch engineers, so why build one? The other issue I see is parts. There should be some drivers floating around but the amps on those subs crap out so frequently, I doubt you'll find a used one. If you did, you'll spend a lot of time fabricating a sub with a timebomb for an amp. You'd be better off buying a driver and fabricating a box using that particular drivers T/S parameters. Buy a new plate amp with a warranty and enjoy. Quote Link to comment Share on other sites More sharing options...
enhanced250 Posted July 29, 2011 Author Share Posted July 29, 2011 I guess my original post was alittle misleading. I already have a perfectly good working sub-12 and amp. I was just curious if there was a modification or a new DIY box design that increase the perfomance of the sub 12 driver and amp before I went on the hunt for a whole new setup.

CECAA850 Posted July 29, 2011 Share Posted July 29, 2011 I believe the Klipsch engineers wrung every last bit of performance out of that driver and amp. I'd be REALLY surprised if there was a ported configuration that could give you more. You might make a box that was tuned lower but you'd decrease overall output plus, the high pass filter built into the amp would cut output below the original box's tuning point. There's also the possibility of overexcursion of the driver if you could get a lower signal to it. If you build a box with a higher tune, it wouldn't be as good for HT but may get slightly louder for music. Your call. Quote Link to comment Share on other sites More sharing options...

Actually, the best improvement would be experimentation with placement, or adding an identical sub and flattening the response with two. If you corner load a sub you get a huge gain at certain frequencies. Quote Link to comment Share on other sites More sharing options...
MikeFord Posted August 15, 2011 Share Posted August 15, 2011 What is it not doing for you? For some DIY ideas take a look at http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=536 Or try my own personal idea of a dream subwoofer, take a 12' tall Sonotube concrete form 60" in diameter, seal the top with a plate, and put four EV 30W woofers in the bottom. Prepare for liftoff. Quote Link to comment Share on other sites More sharing options...

MikeFord Posted August 22, 2011 Share Posted August 22, 2011 60" x 12' is a standard size for Sonotube, the four EV 30W are the hard part. Quote Link to comment Share on other sites More sharing options...
