I don't know exactly where this belongs.
Recently, I had trouble with my laptop. Youtube videos will play fine, but then spontaneously freeze after two seconds, and all sound will not work. I thought it was a sound card problem, and that is yet to be fixed.
However, I tried switching speakers. I got new JBL Creature II speakers for christmas, with this huge subwoofer. (Well, for a LAPTOP PC, yes.) But it was not working, and only the small satellites would work. I tried to check all connections, and even almost returned the speaker!
But the reason was, in the beginning, I pushed all the dials, Bass And Treble on the subwoofer to the + side. I thought this would give a huge sound, but it actually killed it all. I had to move it to the - side, and it is fixed!
This thing blasts a TON of air. Papers on my desk actually move with this thing. IT's like one of those AirZooka's. It makes a nasty farting noise too, sometimes when it's too high.
