 MAXIMUMPC APRIL 2004


H


idden from prying eyes and pro-
tected by keycode access and a mis-
sile defense system, the Maximum
PC test lab is the most secretive of places.
Only a handful of employees receive
access to our vault-like den of hardware
depravity it’s tucked away in a corner of
the building not freQuented by our par-
ent company’s 150-plus employees. Sure,
once in awhile an errant employee steals
a glance when the door swings open, but
in general no one other than us is aware
of the lab’s goings-on.
This month, however, everyone within
a 100-foot radius was aware of the fact
that we were testing subwoofers. In our
defense, we’ll admit that when +lipsch
first offered to send not one but 12 of its
SWS subwoofers for testing, we should
have resisted. We should have said,
hWe have enough bass, thank you very
much.v But we didn’t. We’re weak, obvi-
ously, and easily swayed by over-the-top
PC power. Hey, who isn’t
We started by hooking up three of the
subs to a set of +lipsch ProMedia Ultra
5.1 speaker set by daisy-chaining them
together. One nice feature of the SWS
system is that a single volume wheel

controls the output of the
entire array, so it’s easy to dial
up the appropriate amount
of bass.
hAre these subwoofers multi-
plyingv asked Editor-in-Chief
George *ones upon finding
another stack of three subs
later in the week for a total
of six . ,ittle did he know, the
bug had just begun to take
hold. One week later six sub-
woofers had become a massive
12-sub array that shook the
labˆand everything around
itˆlike a 9.0 earthQuake. The
level of bass felt so unbeliev-
ably powerful it was comical.
For example, when standing
near the subwoofers during
testing our pant legs actually flapped
around like flags in the wind, not
because the speakers’ ports were facing
them they are located on the speakers’
rear but because of the sheer strength of
the sound waves!
Unfortunately, right as we went to
press with our review of the SWS,
+lipsch informed us of its decision to

clear out its remaining stock of subs at
the bargain basement price of $99 and
cease selling the productˆfor now, at
least. Because we’re not into recom-
mending products you can’t buy, this
means we had to shelve our review the
verdict: a 9 rating and a +ick Ass award .
This also means we have the last 12 SWS
subwoofers in captivity. Send your bids

Conventional wisdom says it doesn’t
matter where you place a system’s
subwoofer because the deep tones it
produces are nondirectional. While this
is generally true, we’ve discovered it’s
still possible to get better sound from
your subwoofer by experimenting with
different locations. Here’s how you can
find the sweet spot for your bass.
Unplug every speaker in your system

except the subwoofer, and place it in
the exact spot where you’ll be sitting
when you listen to your speakers (if
you can). Play a bass-heavy soundtrack
and crawl around the room, listening
for where the bass sounds best. You’re
probably asking, “You really want me
to crawl around the room?” Yes, we
really do. It’s a lot easier for you to
move around the room than it is to

move the sub. You are looking for the
spot where the subwoofer sounds the
best to your ears. Once you’ve located
the spot, place the subwoofer there! To
save time, start in the far corner of the
wall where your PC (or home theater)
is located, and walk along the walls
so that you hear how the bass sounds
from both sides.

The sensation of 12 100-watt subwoofers pounding away on either
side of you is pure torture, which is why we had our new intern test it
for us. Sadly, the massive bass blast drove poor John insane.
