haha....using blue thunder 3 for quite sometimes already....before that is use blue thunder 2..but kena ppl stolen when i bring to an event at a hotel....
actually when pair with a good sound card the sound from the speaker can be very nice one, i used AV710 with this speaker...the sound was perfect especially the bass...it was amazing compare to the crappy sound from onboard soundcard...
i agree with eyerule that their sub cross over frequency quite high which make the sound boomy, but when paired to the right sound card the speaker also can sound right one...
so...those ppl who use their speaker on a crap onboard soundcard and trying to blame the speaker as the source of the problem, i think u should try replace ur soundcard...onboard soundcard was meant to use for small speaker only..when u wan big sound, u will hear the difference in quality......
