hi need advice on subwoofer replacement

[TLS Guy]

To be fair it does sound like OP was happy with his Polk sub until it died.

You have made my point though, the thing DIED!

I get you but the sub may be 10-11 years old. Everything has a shelf life.

I encourage the OP to wait a bit longer. Can they save another $100 a month for 3-5 months and get something that will really perform? Still will only get 1-3 year warranty parts dependent most likely.

OTOH the driver in the 505 could well be fine if you just used another amp....

Doubt he has had it that long. Those things are known for blowing up at an alarming rate. I don't know how Polk have had the nerve to keep producing it that long.

You really can't expect a sub produced for $300 to be any good. Just consider making a box, as driver and amp for that money. It just does not add up.

The driver almost certainly is fine. A new amp is half the cost of that sub. There is no drop in replacement, so there would have to be slight modification of the box.

This plate amp would do the job. It is half the cost of that sub, which is now discontinued.

Or just leave the old plate amp in place and get a different form factor for amp (or I've even seen some just use another plate amp uninstalled). Depends on how much you want to fool with the box as well as budget.

You can NOT leave a plate amp uninstalled, as they are open on the side opposite the plate. So dangerous high voltages are exposed. You can not seal that off, as it needs to be open for air circulation.

Wouldn't be my recommendation, but if mounted well could be done. I'd rather use a pro/rack amp.
