Can someone point my in the right direction for this? I am looking at using a 10" or 12" sub-woofer for a mix of home theater and music use. I would like to keep the cost down as much as possible and still sound pretty good. I am looking at using a 250-500 watt plate amp. I have not decided on the woofer yet, so i am looking for suggestions on that as well.
I found a klipsch RW10 on craig's list for $50. Should I jump on this? There is a small tear in the woofer. I figure i can buy a woofer to replace it from parts express. I am not real sure i could even build a box for $50.
While I can't comment on the price, I wouldn't buy it for the box. The driver may be easy to repair (get it air tight... I'd try craft glue with tape to clamp), but it's a ported box, so you'd either need a matching driver, or a plug in the port (make it sealed).
If you aren't aware, speaker acoustic characteristics are described by "Theil/Small" parameters. These parameters are all you need to predict a woofer's response in many applications, like ported boxes. That's what makes driver replacement problematic - matching T/S parameters. In sealed boxes, it's not a factor, thus the advice to plug the port.
