how loud is this loud? sure.. i kno creative woofer can tahan
loud. but at "loud" it just becomes blaring of what's known as
low-midrange, not bass.
altec can be very loud oso.. just make sure u get the right one,
dun expect altec BXR1121 to go party-volume loud.. party loud =
MX5021. 
no offence in this tho, just let you know my views
