Lo all :]

Can anyone point me the direction of guide as to how best setup a sub for use in a HT setup? Purchased a Rel Quake today to compliment my B&W's but I'm not entirely sure that it's calibrated correctly.

I have the following controls on the sub: contour (either set to depth or slam), roll-off, mode and lo-level. The manual makes reference to phase, crossover and gain which I'll admit is slightly confusing me.

For example: "Adjust the crossover to a point where the sub and the speaker are sure to share frequencies (B, 3 for big speakers or C, 4 for smaller speakers" If anyone could explain that, it would be greatly appreciated :]

Cheers in advance.

Nick.
