Hi Julf! I take your point about the difficulty of designing an effective passive filter to do the job. Obviously it would still be better to disperse surplus heat in a filter component intended for the purpose than to overheat your speaker voice coil. Neither my amplifier nor my speakers have shown any distress so far so hopefully I've got both sufficient clean power & resilient enough voice coils for it not to a concern in practice. Will sleep better now, thanks!
