I have owned a pair of SL3's for 20+ years (also Aerius, and Cinema). The SL3's have been unused for some years. I tried hooking up and one has a non working woofer. I took the rails off. All wires are connected and were rechecked. The woofer looks fine. The panel works fine, just no bass. Connecting directly to the woofer posts doesn't work either. Absolutely no sound. Could the woofer be bad or is this more likely a crossover problem? Is it worth fixing or should I try to sell my panels for salvage.? My Aerius work well with a Paradigm sub and Sunfire Amps and are more than adequate for the room they are in. Opinions?
