I read your comments, but objective measurement would make dialing in the required degree and range of damping effect would make a 'one size fits all' device unnecessary since the weight of speakers varies so much.\n\nNever been a fan of buttkickers. Tactile sensation varies, according to the person. I had a Mazda RX-7 with a subwoofer behind one of the front seats and when I was driving with another person in the car, he asked if I could turn the bass down because he was becoming nauseated. I didn't feel it in the same way because I'm a lot bigger than he was.\n\nSo far, I haven't heard a system in a residence that 'felt' the same as a live show. I have heard loud, strong bass, good presence and airy sound, but it never sounds the same and a large part of the reason is obviously the power of the systems\/speaker size, etc but the number of variables is large. I can't begin to estimate the number of times I heard people say "I want it to sound exactly the same as it did in the studio when this was recorded" but that really shows the lack of understanding about how music sound in studios and how it's recorded. I think we search for sound that we inherently like, but the hardest part of finding it in how we aren't able to put our description into words. Most equipment choices are compromises to some degree because we may not be able to afford what we REALLY want or maybe, we just haven't heard what stroked our hair the way we like, if you know what I mean.\n\nBy any chance, have you heard the large Steinway-Lyngdorf system?\n\nSo true about live concerts right! I saw Sting at the Worcester Centrum long ago and oddly enough where we were sitting the bass was almost too much—punching and penetrating like an X-Ray with the opening act. Haven't experienced anything like it before or since. It was actually an unpleasant sensation\n\nAlas no, I have not yet had a chance to hear the Steinway-Lyngdorf system! Funny you should mention Lyngdorf. It came up in conversation last week and I've been looking at the MP-60 2.1 specifically. The specific context of the conversation was the different approach to room EQ with Room Perfect and I was seriously thinking of asking for a review unit to take it for a spin.
