b_limo, i agree with several other members that you are probably pushing your speakers too hard.
My understanding is that voice coils are very inefficient in converting electrical energy into mechanical (pistonic) motion energy - we are talking 2-4% efficient - hence voice coils can get hot pretty quickly.
I also am wondering whether the speaker is not manuf totally correctly in that there isn’t sufficient clearance between the insulation materials inside & the voice coil magnet so that when the voice coil is getting hot, it’s touching the insulation material & that material is outgassing....
I've had B&W ported speakers myself & a family member has ported Green Mountain Audio speakers + I've heard my friends' ported speakers (such as ATC, Von Schweikert, Star Sound Caravelle, etc) & never smelt the speaker when we were rocking.
