cs 245i trouble

Hi all,
I bought a used cs245i center channel a while back. I hooked it up to a Yahmah 345
5.1 receiver with paradigm mini monitors for rears, Mission 707's front, psw 300 sub. The receiver shut down after about 10 minutes never to work again. I purchased a new
Sony str dh 810 receiver before x-mas and hooked everything back up. After about 10 minutes the receiver went into protect mode which happens when there is a speaker overload. I hooked up a different book shelf speaker to the center and had no problems. I inspected the cross over and it shows no visible signs of failure. No loose wires or burn marks. What is the likely cause and is it worth fixing? I paid $50.00 for it last year used.
Thanks

Doing good so far, you've ID'd the CS as the likely issue. Now you are looking for a short. You will need to get your hands on a Volt-Ohm-Meter (VOM).
Since the shutdown occurred relatively quickly, I'm assuming you have a static, and not a dynamic issue. You are going to be disassembling the speaker to some degree, maybe completely, but we may get lucky early on.
Start with a reading at the terminal of the speaker. The 245 is a nominal 8-ohm speaker, so expect to see a reading well under that value. If you do...
Next you'll want to check each of its two MW's and its tweeter. When checking these remove at least one of the speaker leads to isolate the individual MW/ tweeter from the rest of the circuit. If any are bad, you should see a zero/ near zero reading. If none are bad its either the x-over or internal wiring.
Happy hunting and welcome to the Club...More later,
Tour...
