    Hello All, I haven't posted for a while (i know it sounds crazy, but money has been going to things other than HT)

    the SVS is $599.
    I can get the DefTech for $650.

    Room is fully enclosed theater 13 x 15.
    Ceiling slopes from 7 foot front to 9 foot center and back down to 7 feet in the back.
    1 riser in the back for second row seating, decoupled wall sound insulated.


    Any thoughts?

    From what I've gathered around the various forums is that the SCII claim of 14hz is a complete sham and that it cannot go into the mid-20's even without running out of gas. It might be a nice little sub for music listening......I know the SVS will go low and do it accurately.

    i wouldn't believe anything that def-tech states about their subwoofers without first hearing it in person,
    i used to be the owner of a def-tech pf15+(bought it based on magazine reviews and tech specs).WHAT A PIECE OF CRAP THAT SUB WAS!!!!!!!!.
    Then i bought an SVS sub and got to hear and feel what real bass should be like!!! YEAH BABY!!!!! i can't tell you how fast that def -tech got thrown out of the house. LOL.
    I would go with the SVS if i were you.[​IMG]

    The DT SC II faired badly in Nousaine's standardized testing.

    (spreadsheet courtesy of Fabulous Frank Carter)

    Without delving too deeply into what the numbers mean, it cannot generate significant sound pressure levels at low frequencies without badly distorting.

    The SVS, OTOH will provide much cleaner and louder output, deeper extension, and a flatter frequency response. There will really be no comparison between these two subs - the SVS is far and away the superior unit, and for less money.

    This review is for the 25-31PCi, but the PB1-ISD is functionally the performance twin of the 25-31 PCi, so JJ's comments can also be applied to the PB1-ISD without qualification. In fact if you want to split hairs, the ISD will go a bit deeper than the 25-31 PCi.

    I wasted money over the last few years going with dual NHT subs and also Def. Tech. Then I finally got wise or should I say something just told me I had to try this SVS everyone was raving about. Sure glad I did and sure glad I finally got one. Make the others sound like crap and for alot less money. I could have saved several thousand dollars had I done the SVS in the first place.

    I have a def tech sub. It's a 15 inch, cant remember the model number, but it says it goes to 14 hz. I love it. It goes LOW and plays pretty loud. A little boomy, but not bad. retail was like 800, but I paid 700 from soundtrack on sale. Sounds good to me.

    I used to think I had it good running a 8" Kenwood and then the WM-40 and then the dual Velo's and then the AV15 and then/ ok I'll stop.

    One thing is for certain though. If you want high/flat SPL in the lower freqs? Something to be experienced. SVS is one very good option. About the best imo considering performance for the $$.
