I'm using Logitech Z560 now..compare with the ultra
treble..much more clear and more treble than the logitech (very obvious tim..the treble of 560 sucks)
mid....not a big different..coz 560's mid is very powerful too
bass...ultra's bass is much tighter than 560..yes 560's bass is loud but it's very 鬆散 compare with ultra..
if compare with the old promedia 5.1..all I can say is the mid and bass is improved..especially the bass..
anyways...that's my opinion about the new ultra..
