Floridapoolboy, boulderdaschhi, and Skismuggs - thanks for the feedback.
"Try it and see how you like it, just keep increasing the receiver crossover until it sounds good. You could also wire the Basscube to the speaker outputs, and use it's own crossover, which may go higher than your receiver does."
Floridpoolboy - As I stated above, I've kind of been living in the stone age and I am a little intimidated at this point with my new receiver - I'm slowly reading the manual and trying to comprehend all of the material.
So, I'd like to try you're approach of "increasing the receiver crossover" but don't know how to go about doing that. Can you get me going in the right direction?
