TEST REPORT

P L U S

Outstanding multichannel performance.

Impressive bass, full-range dynamics.

Bipole/dipole-selectable surrounds.

Changeable side panels.

M I N U S

Big subwoofer.

Center-speaker base a little too high.

the left and slightly behind the front left

speaker.

The 4200 LR front speakers are true sat-

ellites, not intended for use without a sub-

woofer, 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 place-

ment. 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,

while the treble added signiﬁcant air and

life to the mix. And that touch of "hoo"

caused by reﬂections from the screen dis-

appeared almost entirely.

The Atlantic Tech system punched out

multichannel music with ﬁnesse and im-

pressive impact. The DVD-Audio mix of

Donald Fagen's Kamakiriad solo album is

an amazingly pristine production in both

its recording and performance (almost an-

tiseptic), and the System 4200 showed its

virtues to a tee: preternatural clarity — es-

pecially 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 lis-

tening to Fagen's "Snowbound" repeatedly

at ever-increasing volumes, reaching a lev-

el that audibly sweated the front-speaker

trio some 10 dB above THX reference lev-

el — and that's loud.

One advantage of a system that's prop-

erly 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 "Snow-

bound" was deliciously rich and punchy,

yet with the superb deﬁnition and "quick-

ness" that only an excellent sub and an ex-

pertly 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: bi-
