Unfortunately, with any room eq, depending on your environment, the results can be varied. I recently bought a Marantz 5003 AVR that I am using as a pre-pro with outboard power amps. This has the Audyssey 6 point multi-eq I assume is similar to the new SVS unit only the bass eq will go lower. I also have an SMS-1. I wasn't particularly impressed with the results of the 6 point eq as in an effort to balance the response at the low end, they tend to cut the sub output back too much thus you don't hear much below 40hz. The SMS-1 gives me the option of increasing that REAL bottom end that in studies show our ears don't hear as well. I agree with fredk. Before you spend money on this unit, assuming you have the space, buy another sub.
Whatever eq process is used and no matter what the graphs show on the screen, I find, after spending countless hours playing around with this stuff, in the end, my ears are generally the best arbiter of sound preference .
