Haha, sounds like some dubstep your rockin.
Dubstep normally blows speakers by their voicecoils getting hot and locking up. The 'weight' of dubstep that makes it so crazy with bass is mostly sine waves and LFO, so you have to run your speakers closer to their program power versus peak or you'll melt the coils (which is what you smell). Normal music has breaks inbetween the bass hits that allows the coils to cool....dubstep doesn't let up. That's why when you play dubstep on a big system the room pressurizes and doesn't let up, because the subs are adding that 'weight' as they call it. Nothing beats some sick dubstep on a big system though.
I love "Nero - This Way" ... great bass track:
That drop at 1:23 wwwooowww.
