Ok, I won't bore you with the usual review about how great this sub is because you've heard it all before and my experience has been no different. For dvd's I am running it around 6 db hot and it sounds/feels amazing, unbelievable, yadda yadda yadda. Setting it up for music is where I went off the deep end(get it - DEEP end? uh sorry, bad pun). I first tried it with the recommended mains set to small and crossover on the sub disabled (same way I watch dvd's) and while I was impressed I felt I had to experiment more. I set my mains to large (which are pretty flat down to around 35 hz) selected "both" for bass and set the crossover on the sub to around 45 to 50. Then I really lost it and turned UP the sub another 5 db. The results completely kicked my ass!!! I felt the music like never before without getting annoyed by feeling distracted because the sub was too high. Now, let me give you a disclaimer. I love metal/hard rock. To give you an idea, my favorite bands to listen to are 80's Metallica, Dream Theater, Iced Earth, Tool, Fear Factory, some Iron Maiden, some Megadeth (esp. Rust In Peace), old ACDC with Bon, Queensryche, and on occasion some Slayer and Pantera. My point is that I'm sure this is a terrible sub set up for other kinds of music like classical and jazz. I know that my frequencies are so far away from flat that it would make any audiophile cringe to read this. However, TO ME it sounds/feels like I have always wanted my music to sound/feel and I'm not giving it up unless of course I could do damage to the sub. I generally listen to music anywhere between 80 and 95 db, so I am hoping that this will give the sub plenty of room since I am boosting the low end so high. I guess my main reasons for posting this is so I can be sure that I'm not damaging my sub, and maybe somebody else will try this kind of set up and reassure me that I'm not completely insane. Thanks for any comments. ps, this is one of the most exciting weeks of my life as far as this hobby is concerned. First I receive a svs sub on Tue, and then this Fri. I am getting my new mitsubishi widescreen 65809 delivered. Just though I would share the joy!
