The OP didn't mention anything about a tweeter, I'm very literal and since he mentioned "subwoofer" I'm assuming that's what he meant and that this sub-woofer either has an integral amplifier or an external power amplifier. I suspect he is probably talking about a typical home theater speaker package. Hopefully he will clarify what he means.

The OP has not mentioned whether this is a reflex, acoustic reflex, horn or bandpass. I suspect based on limited experience that clipping will be less obvious with a bandpass box than the other types.

The issues I can think of are running out of xmax if the woofer power handling and box design result in insufficient power handling under the specific clipping situation, and potentially overheating the VC.

A limiter and/or compression ahead of the power amplifier has been a traditional way of handling these issues, but of course just turning the volume down a few dB could be helpful as well.

Hopefully the OP will tell us a bit more about drivers, box(es) and amplifiers used, and whether the issue is mainly LFE related or more generalized.

A friend suggested me to use a small incandescent lamp in series with the tweeter. As power increases dangerously, lamp glows increasing its internal temperature, and then its resistance, limiting power at the tweeter coil.

It will help but your music will be missing the high end. The above light fuse is what you need, but it has to match your tweeter (power).
