SHAKE, SHAKE, SHAKE THE
ROOM
What does 1000W of peak power mean to you? It means having a
subwoofer that delivers rump-shaking bass night after night. It
means getting class-leading power and output. To accomplish this,
the SRM1801 features Class-D Fast Recovery™ amplification.
Class-D amps are more efficient and lightweight, with far less
waste heat produced versus competing designs. Fast Recovery means
you can occasionally push into clipping without a ton of nasty
distortion. So, power is no problem... but how does it sound? The
SRM1801 benefits from built-in Active electronics, like a precision
crossover and tuning filters for accurate bass response. Some
subwoofers have decent power, but when you listen, everything
sounds loose and flabby. The SRM1801 delivers professional low end
that you can feel...custom tuned to be tight and punchy.
SYSTEM FRIENDLY
Paired with a Mackie SRM450v2, you have a complete (and completely
affordable) “plug and play” system that is ideal for
small clubs, DJs or rehearsal spaces. The SRM1801 has both
full-range and high-pass stereo outputs for connection to
full-range top boxes. Just dial in the appropriate level and use
the polarity switch to make sure the sub is in phase with the top
boxes. The integrated pole-cup can accommodate a standard mounting
pole, so your favorite speaker has a nice place to sit. Or you can
just stack your full-range box right on top...the SRM1801 ain't
picky. It's also a great match for the popular Mackie TH-15A and
can easily integrate into nearly any existing PA setup you may
have.
THE
COMPLETE PACKAGE
If you are looking into getting a subwoofer, than you probably have
the following criteria in mind: You need as much power as possible.
Well, the SRM1801 offers class-leading power in its price range.
You need it to go low...body vibrating low. The SRM1801 has a
high-output 18" woofer that can be felt from across the room. It's
got to be easy to move and built to last. The SRM1801 incorporates
features that make it lighter and more portable than the
competition. Plus, it's made with rigid plywood (not fiberboard) to
handle the rigors of the road. So, if you are looking for
professional quality, portability and impressive low end for your
SRM450v2 system, you have to check out the SRM1801. Use the Find a
Dealer feature above and get yourself a demo today.
