    Be still my heart.

     Hopefully you've awakened from skipping "Reading and
     Comprehension 101--Remedial" by now.   

     Where did you get the wacky idea that TWO subwoofers inherently
     have a 6 dB advantage over a SINGLE subwoofer?   Somewhere
     doesn't the actual POWER (and efficiency) of the subwoofer and
     amplifier come into play?

     BTW, I usually advocate paired subs....but not for the reason
     you gave.

    He's also willing to allow ME to play with the level controls
    and crossover frequency.   

    Turning your challenge around, have YOU actually listened to the
    M&K and Velodyne subwoofers and the HSU, or are you just
    gatemouthing?

     That's putting it pretty accurately and mildly.

    I implied no such thing....you really ought to stay awake a bit
    longer before hitting the "F" key....

    WHERE in the posting did you see that I would prefer the lower
    end powered subs....actually I was recommending against
    them...or even comparing them to a good subwoofer.  

The Hsu SW10 subwoofers reach down to 20Hz!  Even the inexpensive dbx 
>subs could probably reach 30Hz.

   Actually the low-end M&K's and Velodyne's I mentioned are flat to
   just below 30Hz...but in my non-humble opinion, 30Hz is
   definitely NOT subwoofer territory.   Nor would such a model (as
   you seem not to have noticed) compare favorably in performance to
   a good passive sub such as the HSU (or even the CV "earthquake"
   sub...) .

   Thanks for making my point....if you grab your local Velodyne or
   M&K dealer by the wallet, you can get a GOOD one of their models
   for about that amount of money.  That are flat, with low
   distortion, down below 20 Hz.   And louder than the HSU's will
   tolerate.  

   [We won't mention the facts about whether you NEED a lot of deep
   bass and whether it need track midrange power accurately....you
   can read Fletcher Munson curves, hopefully...]   

   As I said, I really have nothing against the HSU's....just that
   there are alternatives in the same price range.  I mentioned two,
   there are several others.   

   They are good subwoofers, but they don't have the power handling
   to fill a room with rib-rumbling bass...and in case you missed
   it,...neither do the low-end powered subs.       

The only

    Good advice, take it yourself.   AFTER you've had the
    opportunity to listen to the alternatives....
    I presume the fact that you own the HSU's makes you totally
    unbiased?   Riiiiiiigggggggggghhhhhhhhhhht.
