Louder than M60s? Holy crap Dude! How loud do you listen?
Even with just a 110 watt/channel amp and M60s, mine can already play ear-splitting loud at clean levels in a larger area.

Perhaps you were just referring to increased bass levels? The answer is probably a definitive "yes" to both scenarios but my ears hurt just thinking about it if you meant volume in general.

With great power comes Awesome irresponsibility.
