Building Sonosub from existing Sub (1 Viewer)

[Robert_Hill]

I have an old, but in good condition Polk Audio PSW120. It's got a 120w amp and an 8" driver. I would like to disassemble it and use the components to build a sonosub-style sub. Can anyone help me determine dimensions? Looking for a little more sound from the amp/driver combo. I can get the tube and mdf for free, so it's a low-buck project.

I'd suggest saving the 8" woof, and spending some minor bucks on a 10" or 12" woof, and using that and the existing amp - save the polk box too...

ANy suggestions on the woofer?

There are a few good cheap woofers on parts express. Which one to buy depends on how much money you want to spend. Here are two cheap woofers.

I found a used Shiva for $50 + s/h. If you can find a used DVC 12" or shiva you should definitely go for them.

Recycling the amp isn't a good idea. Most of these pkg subs have built-in EQ specific to the driver and the box it comes in.

Save up until you have enough to buy both a new amp and driver
