I built stereo subwoofers, each tower has 4 12" drivers each. Here is the thread where I discussed them.

Here is a picture of one subwoofer.
http://www.polkaudio.com/forums/attachment.php?attachmentid=10899&d=1126217988

Willing to sell the pair for 800.00 including the Beringher BFD. Basically 100.00 per driver. I can ship these via truckline but is $$$.

Or, if I can sell drivers in lots of 4 (either 1 person buys 4 or multiple buys taking 1-2-3 of them) Drivers 100.00 each plus shipping


Willing to talk about most any deal you can come up with, always interested in trades, but cash is KING.

    New Year Day bump.

    These drivers are great for car subs also.

    Make an offer, I am in a good mood :)

    I am not sure Brad, I have a test CD I use for setting them up and it goes to 20, I use the EQ to make them as fat as possible in my horrible basement room. The drivers are each in a 1 cubic foot box sealed from eachother. This makes a very tight bass, but with the smaller cabinet for each driver means you have to boost the extreme lowend, I use the beringher for that. I wired the drivers so I have 4 ohms in each cabinet. This produces serious bass, I get 20 hz with huge output when asked.

    How did you wire the subs for a final Impedance to the amp ( Series/Parallel Combo) . I usually go for a 4 ohm final when using multiple woofers for home...nice job by the way.

    Assuming they are 8 ohm/sub, you wire each pair in parallel to get 2-4 ohm circuits then put those 2 circuits in series.

    If they are 4 ohms each, then you do the opposite. Put 2 subs in series, then put those 2 pair in parallel.

    3 subs would be a bit more complicated.

    Yeah, good idea. Hold onto them until I'm able to purchase them.;)

    In the meantime, design & build an external crossover (or use a Behringer) and top off the subs with a couple of mid/tweet modules. That would be cool.

    Silly rabbit...I know how to do it...I do it on a weekly sometimes daily basis :) I was just wondering what he WANTED his final impedance to be...load wise for the amplifier he used and what the future owner needed to plan for.
