This manufacturer's customer support was incredibly helpful. You do need to be sure that you can correctly add these to your sound system before purchase. In my case, I got lucky and had the right amps to power them. Our P.A. system now sounds 10X better.

I got them used for $150, pulled the carpet on one due to voids & separation in the ply's (these are plywood). Used good max strength glue then fiberglassed & enameled then bed linered it. The other I pained the carpet with 4 coats of latex paint to stiffen the carpet then sanded with a orbital sander. Once solid I enameled it then painted with bed liner. I added a strip of bracing to the sides back & top & added glue to previous braces. I also gloss enamed the interior. Punch even @ low volume with a 10 watt stereo receiver.
