    Bottom Line:   
    If you are looking for a killer Sub for HT then you found the right sub. I picked this up on Ebay as a Refurbished product for $1900 shipped. The seller is "bajawaverunner". In any case, this sub puts out bass that will literally shake the room. Movies come to life in a profound way. It is visceral.

    It's only weakness is with music. It's not as tight as other subs I've heard and seems a bit sluggish. To be clear, it is a good music sub but an INCREDIBLE HT sub. The bass waves literally move throughout our house, and our pad is 6,500 sq/ft.

    Last, Def Tech needs to be more honest with their ratings. This sub will not drop to 14db. Mine hits 20 with absolute authority but begins to roll off around 17-18. 23 is, of course, about as low as you need. It's just that I want Def Tech to be upfront with buyer. Nonetheless, this sub comes with my highest recommendation for HT, and a good recommendation for music.

    Bottom Line:   
    Just got it today to replace a Paradigm PS 1000. Noted after watching the most recent Harry Potter movie that the PS 1000 was not keeping up with the impressive soundtrack. The improvement is dramatic with smooth, undistorted, extended bass of epic proportions, can't wait to watch more movies. Hard to believe that more money could buy more performance!

    Strengths:    Gut wrenching bass. I cant use its gain past 40-50%. Unless of course I want to show off to the guys. Wife friendly. Doesnt take up much space and looks nice too.

    Weaknesses:    It is very sensitive to placement. Start with is at your sweet spot and crawl around till you find a perfect spot and if you can place it there. Unless you want ungodly bass just put it in the corner.
    Kill the cat before you unbox it or you will be sorry. Was faced with the cat wanting to claw it and it only took 2 days to decide which one was staying. (sorry cat)


    Bottom Line:   
    The last subwoofer you will ever buy for HT. It is pretty accurate when it comes to music but can be a bit sluggish. I dont use it for music though. 90% of its use is for HT. Sustaining a flat response to 17Hz in my home @ 105db is plenty for me. The foundations roll like you would not believe. I do believe DefTech is the winner when it comes to HT. Many subs Ive auditioned could go low but not quite this loud.

    Strengths:    Compact, Heavy enough not to bounce around like some do. Also makes it nice for the spikes to dig in and really shake the floor. Plenty of power. Dont even use half of it unless I have friends over. But sure nice to know its there.

    Weaknesses:    Will kill all friendships with your neighbors. Endcaps scratch easy and sock just doesnt seem to go with a 1500 dollar product but oh-well.

    Bottom Line:   
    I would have to agree with the others on this sub. It simply puts the others to shame when it comes to HT. I still think it is a little sluggish for music but only a little. This thing will literally shake the foundation out from under you. I have looked for the right sub for a long time to intergrate into my HT and I believe I am finally done. Money well spent. Doesnt quite reach down to the 11Hz advertized but I measured in my home with room gain a whopping 104db @18Hz. If thats not good enough for you I dont know what is.
