I just plopped mine down in the usual spot where I believe I get the best response without doing much tweaking, I was impressed to say the least but something was lacking, I switched from the up to 5000cf to the 5000 and up amp configuration and my hair was blowing and the wife was upstairs telling me she felt the waves of energy a floor above (concrete floors and ceiling) in my HT. I'm going to try some nearfield listening as well. Hey Ray and Reev, where did you end up with on the sub's master volume setting. This sub has so many possibilities, I'm glad I made custom feet, 2" square blocks with majic sliders threaded on, makes for sliding the sub on my carpet so easy, plus it looks meaner raised off the carpet by the 2"s. Congrats Billy, I knew you would join the club, customer service was my decision to have every PSA sub in my place except the 30, I hadn't heard any of the PSA subs prior to purchasing, once you do there's no going back.
Cheers Jeff
PS...Ray, I'm going to try the Triax right behind my recliner, going with the above 5000 cf setting really did it, after some calculating my space is right around that 5000 mark. I already want another one....
