I was listening to music at a moderately low volume when I noticed one of my speakers cabinets faded and is dull/flat sounding now. I switched the speaker wires and the problem stayed with the speaker cabinet. Could it be a bad crossover? If you got this far, thank you for taking your time to read this, hopefully you can help me out, I'm dumb when it comes to electronics for the most part.
