No. It's the just the lows that drop out and only mathematically. The result is the low notes have no oomph while the speakers move like crazy. That causes distortion best case and mechanical damage if not careful.
"Buzz" + "no lows" is entirely consistent with miswired speaker.
Could be there's a dud speaker there that caused the replacing in the first place? Do a battery test on them for a start.
A blown speaker has a similar effect to one that is miswired, moving opposite to the working one in the lows, and good potential for buzzing too.
