    This is insane!!! I just ran some song demos and movie clips, holy s***!!! This sounds way different, the bass sounds more full, had no humming noise it's silent, way stronger punches, way more low output!! It sounds like a bomb going off in my room! All posters on walls, ceilings lamps, doors, and things I never knew rattle are rattling! I walked upstairs and when you stand on the top floor the vibrations rattle through your spine, it's like a war zone upstairs! As I walk back down through the stairwell the pressure is coming up the stairs like I'm walking through a giant porthole in a sub! I maxed everything out and this sub won't clip, I've got the spl meter riding 129dbs like there's no tomorrow! This sub ain't no joke, insane power, tight clean bass, it's exactly what I wanted.

    "Words that come to mind are tight, clean, smooth, effortless, and deep. Threw in Star Trek Into Darkness (set the sub 3db hot for movies) and watched scene 1.....holly crap! I've never heard or felt bass like that in my system, and the drivers were hardly moving! I can't imagine what it would be like if the Triax was really cranked up. I'd seriously be afraid my room would be damaged. I look forward to getting it dialed in and rediscovering my music/movie collection.

    Reminds me of a line I heard in a movie; "'s big, it's beautiful, and you're gonna love it!""

    "Early reports are in!!! Amazing! I did the right thing, I grabbed WOW and put it in, set the subs to +6 hot and just ran em. Moved to the pod emerging scene and just insane. I could feel the floor Joists moving, my legs were tingling, the air was moving around the room, in your chest punch. Just super smooth, deep bass!! This is all at -7. These subs are for real guys! I don't even have them in place, level matched or tuned yet! Holy Cow.

    Smooth as BUTTA!! These are my first sealed subs and I already love em!! Tom and Jim, my hat off to your guys, you hit it out the park 

    LOL, I am just running WOW right now at -22 and the house is shaking down to the ground, just thundering bass. I am having a hard time raising it to reference.
