Problem is next: I figured out left speaker produce less bass than right.
First I put under investigation my amplifier – Kenwood KA-9100, but after switching speakers between channels I have got same effect - left speaker was out. It is clearly seen when you push 40Hz or 45hz signal from generator to the speakers. Right speaker produces deep clear bass, left one – significantly less, and on low volume – even very hard to hear that some bass is coming out. Next, when I increase the volume level using this low frequencies (45-50HZ) – this left speaker woofer starts rattling, very noticeable, when right one produce clear bass sound. I pull out woofer, run it again – this rattling comes somewhere from inside of the woofer, under the magnet mount.
Strange, that after around 75-80Hz and up rattling disappears. Could it be bad crossover or it is really problem with woofer, like shifting magnet or something like that?
Any advice will be highly appreciated.
