I just bought 20 subwoofers!

I bought the remaining stock of a company that discontinued subs. These were mostly returns with bad amps, but I really bought them for the drivers. Fourteen 12 inch drivers and six 8 inch drivers. Along with 19 plate amps and twenty-two cabinets.

I'm still going through them, most of the amps are bad (as expected), and so far all the drivers are good (as hoped). I have found one working amp so far. If I can find another, I'll be happy. I'd like to keep two working subs and two spare 12 inch drivers (for future projects). The rest I'm Ebay-ing, hoping the deal will pay for itself.

The cabinets are nothing special, about a 15 inch cube, 3/4 inch MDF, no internal bracing, with a 3 inch port. The amps are Chinese-made, probably low quality. The drivers look pretty decent to me. The 12 inch has a huge rubber surround, and weighs about 9 pounds. No markings on them.

I'm thinking about trying to rework two of the cabinets and make sealed units out of them. No plate amps, just passive subs with an external amp. I'm also toying with the idea of two cabinets with two 12 inch drivers each. I was even thinking about maybe a transmission line sub or a horn, but those things are massive, way too big for my room. I don't know any of the specs on these drivers, so I guess I'd better start with the size of cabinet they came in, and play around with that. I'm pretty handy with woodworking, but I've never built a sub before.

Here are two of the drivers, I just sold 4 on Ebay, so now I'm down to only 10!

Get a decent external amp, or just an old receiver and run multiple subs, just screw/caulk mdf covers for the holes where the plate amps were. You can wire 4 with two parallel series circuits to maintain 4 ohm mono load (assuming drivers are 4 each.) If you need 8 ohm loads wire two in series.

I've done this before covering the plate amp hole and running it as passive, works well. You get a little bit extra enclosure volume which tends to help performance on ported subs.

Stack 4 on top of each other in a corner of the room and see how loud it gets

This idea has eviction written all over it, lol.

i thought the same. would have been more suspicious if they were 10's, 12's, & 15's. bad plate amp is their motto.

btw what's the link to your auctions? need some stuff to frankenstein.

Not Acoustic Audio, although it could happen.

You can get Dayton plate amps at Parts-Express.com for $110 or so. (240-watt)

And yes, links to your auctions would be cool.

I thought the Dead retired the "Wall of Sound" in the 70's
