The benefit of bulky speakers is usually better sound
- u know, there's a reason why they build them like that
There has always been a silent battle between speaker constructors and speaker designers because nice design usually compromises the sound. That's pretty much the same reason you wont find any audiophile buying a B&O stereo...
what you prefer is of course your own problem... some throws millions away on speakers they believe sound an inch better than the rest... other's do the same thing for design... i guess it's all priorities.
btw PMB sounds pretty cool with a modded cd-player
