Right out of the box the left speaker has sounded blown. I’m using it Bluetooth mode, and I’ve tried everything that I can think of. Line. Phono. Moving the speakers farther apart, moving them closer together. Switching speaker wire. The woofer on the right speaker jumps while the woofer on the left speaker is imperceptible. They were like this right out of the box. I bought them through Crutchfield rather than Amazon, figuring Bezo’s has enough damn money. I was so disappointed that I ended up buying a pair of Edifier speaks and, though lacking the same depth, at least both speakers work equally well. Can anyone give me some idea what’s going on ? I sure would appreciate it. Thank you in advance, Bill
