The crossover on my Polk CS300 center speaker broke. It's one of those ones built into/onto the back plate, and while messing with the drivers and the crossover, I busted the crossover. I tried fixing it, but it didn't work. Are these replaceable? I don't think it'd be worth spending the money to purchase the part from Polk, and I'm sure Polk doesn't carry old discontinued parts.
I thought about selling the speaker cabinet and drivers online, but I don't think anyone would buy them as spare parts. I was going to build a new center speaker anyway, and thought maybe the cabinet could be re-used, but I don't know. Any suggestions might help.
