Thank You everbody for your help.
I did happan to start adjusting the phase knob on the Descent I didn't know what else to do. When I put it to 270 it seemed to have increased the bass and blended in better with my Summit's. I was able to turn the volume down and still get good response. Still not sure if I should sell the Descent and just run with the Summit's.
I don't understand what this phase control is doing can some one explain this to me.
Thank You
Russ
Phase is to do with the fact that equal and opposite waves cancel each other out - the net effect being nothing (or silence). If your subwoofer is out of phase with your speakers it means that it is producing sound waves of equal (obviously) but opposite amplitude, meaning they cancel each other out.
Obviously you can rectify this by positioning the subwoofer correctly, but because bass has such a large wavelength, you would have to make some pretty drastic changes in position - that is why most subwoofers include a phase switch to switch phase instantly.
As Craig said, this is most likely your problem. The Descent is a great sub, but may be unnecessary with your Summits given your tastes and their excellent performance. I'd certainly be keeping it if you plan to listen to movies through your system, but if it is strictly music only then trust your ears - it may not be necessary.
