satellite speaker systems. Indeed, sub/sat
arrays with six, seven, and even eight
speakers are now the home theater standard, found in “normal” homes as often as
in those of over-the-top A/V enthusiasts.
Boston’s Atlantic Technology can probably take as much credit as any manufacturer for furthering this trend. From its inception 15 years ago, all of its speaker systems have been sub/sat arrays. As home
theater sound has evolved, Atlantic Tech’s
offerings have grown ever more sophisticated. Case in point is its new System
4200, a THX Select-certified suite of compact satellites and a not-so-compact subwoofer. THX certification is a sort of Good

compact, affordable subwoofer/
Housekeeping seal that guarantees the system has dispersion characteristics considered by Lucasfilm to be optimum for home
theater playback.
The 4200 array is clearly descended
from previous Atlantic Technology speakers, but its manufacturer claims several important distinctions for it beyond the new
slanted-back cabinets. First, the drivers are
said to be the same ones used in Atlantic
Tech’s $17,000 flagship System 8200.
Second, the System 4200 features
C.O.R.E. (Custom Optimized Room Enhanced) technology to make it unusually
adaptable to system conditions and room
acoustics. The three front speakers have
both a Boundary Compensation switch (to
smooth out the sound if they’re installed
close to a wall or a big TV screen) and a
three-position treble adjustment. The surround speakers can be switched between
dipole and bipole operation via toggles un-
der the metal-screen grilles, which attach
to curiously strong magnets in the four corners. Niftoid!
The metal grilles on all the satellites are
also a dramatic visual improvement over
the boring black knit on many previous Atlantic Technology speakers. But the most
obvious innovation is the removable decorative side panels, which bring cellphone
fashion thinking to home theater. With the
front speakers and subwoofer, you can
choose between gloss black, maple, or
matte silver. Snapping panels in place was
a cinch, and they looked great.
I set up the system as usual: front L/R
speakers on stands, the center speaker on
top of my TV, and the surrounds (set in
their dipole mode, initially) on high, sidewall shelves. Though the 642 SB subwoofer has a 12-inch driver, it’s barely smaller
than my everyday 15-incher. I placed it in
the best location in my room, which is to

The 4200 LR front speakers are true satellites, not intended for use without a subwoofer, so I began with plain stereo, but
with the subwoofer hooked up, too. What I
initially heard was a “close,” dry sound
with a hint of male-voice chestiness — that
gave me a chance to start trying out those
C.O.R.E. controls.
A bit of experimentation told me that the
4200 LRs are sensitive to vertical placement. I adjusted the stands so that their
tweeters were about even with my seated
ear height and switched on the Boundary
Compensation switches, since they stood
only 18 inches to either side of my TV. The
midrange became more open and relaxed,

The Atlantic Tech system punched out
multichannel music with finesse and impressive impact. The DVD-Audio mix of
Donald Fagen’s Kamakiriad solo album is
an amazingly pristine production in both
its recording and performance (almost antiseptic), and the System 4200 showed its
virtues to a tee: preternatural clarity — especially noticeable on drums and guitars
— and huge dynamic range.
The System 4200 also proved to be one
of those speaker systems that sounds better
the louder you play it. I found myself listening to Fagen’s “Snowbound” repeatedly
at ever-increasing volumes, reaching a level that audibly sweated the front-speaker
trio some 10 dB above THX reference level — and that’s loud.
One advantage of a system that’s properly designed as a sub/sat layout from the
ground up is that you don’t have to fuss

with crossover and level settings. I set the
642 SB subwoofer’s Lowpass switch to
Bypass, skipping its onboard crossover in
favor of my preamp/processor’s, which I
set to 80 Hz. After I balanced levels, the
system sounded perfectly integrated. The
languid, but incredibly solid bass on “Snowbound” was deliciously rich and punchy,
yet with the superb definition and “quickness” that only an excellent sub and an expertly matched sub/sat system can achieve.
The Fagen DVD also provided perfect
test material for comparing the 4200 SR’s
bipole and dipole modes. The verdict: bipole wins. I still prefer dipole surrounds for
movie sound and naturalistically recorded
music, but with mixes that put discrete material in the surround channels — like a
hand-percussion shaker in the right rear —
bipole clearly sounded better.
With this musical introduction, I expected nothing short of great movie sound
from the System 4200, and I wasn’t disappointed. Playback was about as seamlessly
integrated, solidly spatial, and colorful and
dynamic as I could want.

Harry Potter and the Chamber of Secrets is a first-rate 5.1-channel production
with just about every surround sound virtue. Through the sequence of the flying car
catching up to the train, I was struck by
how little the timbre of the engine’s poppop-popping changed as it swooped from
channel to channel and position to position. The quidditch match a bit later might
as well have been designed as a home theater demo: the whizzing balls and brooms,
crashes and impacts were all spectacularly
present and three-dimensional. And in the
