I have 5.1 surround sound for my computer. Well, the sub likes to go on strike fairly often. The butt connector which holds the wires to connect directly to the sub was shot, and had to be resoldered to that direct wire. I can't believe I went 2 weeks without a sub!! my bonnie actually sounds like it had a sub! Some Rammstein that doesn't sound like a flat POS, finally has some full sound!
