Cheap, big drivers

[wmswilson1]

I'm looking for big subwoofers 12+ for cheap. I really don't care about max-wattage acctually lower the better. Do you guys have any ideas?

Thanks,
Matt

I assume you're using them in open baffles? Can you tell us how you've got them set up (baffle size, crossover points, etc.)?

"I assume you're using them in open baffles? Can you tell us how you've got them set up (baffle size, crossover points, etc.)? "

actually...no, they are currently in the closed boxes, two per side, that's what I already had, on top of which sits 12" B&C coaxial open baffle
speakers are quite narrow, not so big looking, crossovers are work in progress, I cross two 15" Jamo woofers at 200Hz, coaxials mid and tweeter at 2000Hz
currently having just 8mH and 0.65mH inductors there and 10uF cap plus L-pad for tweeter, minimalistic, the way I like it...it might all change, biamping is next...but the crossover points might stay
I purchased those B&C 12" coaxes for $50 and two 15" Jamo for another $50...these speakers already sound way better than they should...that's the fun part, getting top notch performance for almost nothing
if you want to see some messy pictures, I can take some...

Pics would be nice. How big are the boxes?

"Pics would be nice. How big are the boxes?"

here are some pictures, its a work in progress
left speaker from the front

 

[adason]

right speaker from an angle

 

[adason]

woofers only crossed with 8mH coil

 

[adason]

the most optimization will be on the coax crossover
the L-pad helps, tweeters in the coaxes are usually much more efficient
its good to have option to dial in the amount of high fr

 

[adason]

correction, its a 4 uF capacitor going to the tweeter (not 10)
plus I added 120uF bipolar (bypased with small mp) to limit low fr going to the 12" midrange of the coax

Where did you pick up that B&C for so cheap?
