Yeah, and as loud as that Jackhammer can get, it's still a piece of ****.
It doesn't sound good whatsoever. I had some guy who's never heard one tell
me I was wrong. I've heard the thing. It's loud, but not as loud as a 300
lb sub should be.

. The largest transducer used in SR
systems would be 18", and even that size of woofer has lag issues in
some enclosures.

Lag issues? Cpt. Howdy and I went back and forth on this very issue and
the
consensus was that as long as the motor structure (magnet, voice coil,
etc.)
is large enough, cone size DOES NOT effect response time (or "tightness,
or
lag-time, or whatever you want to call it). True, as diameter increases,
cone mass will increase exponentially, but again this can be accounted for
in an adequate size motor. The problem, however, with many large diameter
woofers (18" for instance) is that they will frequently use the same motor
structure as their 15" counterpart. This will OBVIOUSLY mean that the 18"
driver will not be as responsive as it's 15" brother.

MTX currently produces a 22" woofer, called the Jackhammer.
http://www.mtxaudio.com/caraudio/pro...jackHammer.cfm This
subwoofer weighs over 300 pounds and a FORKLIFT is REQUIRED for mounting.
The voice-coil diameter is 6.5". Obviously, MTX understands this concept.
