Thank you all very much for your comments! It will take me some time to run down all these suggestions, but it should be fun. Bob, in response to your last post, I run the speaker wires to the subwoofer, then from the sub out to the monitors. There is a single crossover dial on the back of the sub, which I have been setting to about 80Hz. So the monitors are not trying to produce bass, unless the sub is off. But I am intrigued by your suggestion--to scoop out the bass before the signal even gets to the amp section of the integrated--and I plan to try it this weekend. I notice now that the sub has RCA in and out jacks; the out jacks are labeled "80Hz high-pass output." So I guess Velodyne thought of this too. Thanks again for your very thorough comments--Alex
