Knowing a good thing when
they spotted one, mainstream speaker manufacturers
greeted the arrival of home theater with outspread
arms, falling over themselves to accommodate the exploding
demand for six-piece speaker packages. In contrast,
high-end speaker companies were late to the party.
Blinded by stereoscopic vision, or perhaps a lack of
enthusiasm for movies, many high-end speaker manufacturers
have only recently tossed their hats into the surround
sound ring.
MartinLogan is an exception.
The Kansas-based manufacturer of electrostatic speakers
featured a center-channel model in its line as far
back as 1993. And while the company continues to push
the outer limits of audio exotica (its flagship, the
Statement, sells for $70,000 a pair), it has also made
overtures to the mass market by designing a series
of lower-price electrostatics. The home theater system
I reviewed consists of two such models, the Scenario
($1,995 a pair) and the Script ($1,695 a pair), packaged
with the company's $1,295 Cinema center-channel speaker
($1,495 with stand). That adds up to about 5,000 bucks.
To most people, that's a lot of money to spend on speakers,
but then again, this isn't your average system.

Conventional dynamic speakers
translate electrical signals into sound by first turning
it into kinetic energy that moves some combination
of cones and domes. Electrostatic speakers, in contrast,
move air with large, flat, microscopically thin, and
electrically charged diaphragms suspended between pairs
of charged metal "stators." An electrostatic speaker
needs to be plugged into an AC outlet, and the signal
from the audio amplifier is fed to the diaphragm. Variations
in the signal voltage from the amp pull the diaphragm
closer to one stator or the other, which moves air
and produces sound. Since the diaphragm is driven uniformly
over its entire area, an electrostatic speaker has
the dual advantages of low distortion and lightning-fast
response to transients. It's also a natural dipole,
radiating equally and in opposite phase front and back.
The drawback to the electrostatic
approach is that you'd need a massive diaphragm to
reproduce bass frequencies a problem MartinLogan sidesteps
here by combining the panel drivers with conventional
woofers. This hybrid approach permits the speakers
to have attractively slim profiles.
The pair of Scenarios
that handled the front left/right channels in the system
I reviewed are the most striking speakers I've laid
my eyes on in some time. Each speaker stands approximately
4 feet tall, with a sealed cabinet containing an 8-inch
woofer occupying about half that height. The steel
electrostatic-panel assembly is joined to the front
of the woofer cabinet and curves slightly in an effort
to widen the speaker's horizontal dispersion.
"I could
hear delicate details, like the scraping of the bow
against the violin strings, and when the layered interplay
between violin and cello kicked in during the piece's
second half, the imaging was so sharp I felt I could
pinpoint the respective instruments."
The Scenario's front-firing
8-inch woofer, which crosses over to the panel at 500
Hz, is rated down to a modest 45 Hz, so unless you're
stuck on a strict diet of dialogue-heavy Merchant-Ivory
period movies, you'll want to add a separate subwoofer
to augment the bottom end of music and movie soundtracks.
MartinLogan recommends
its Script speakers for surround use. These are designed
for wall mounting and come with brackets that permit
180 rotation so you can adjust them for either direct
or diffused sound. Standing 43 inches tall, the Script
combines a relatively small electrostatic panel with
a bass module containing a 6.5-inch woofer that plays
down to about 70 Hz. Since small panel-type speakers
like the Script have limited vertical dispersion, for
the best results you need to mount them so your ear
is about level with the panel's midsection.
If, like me, you feel
that most center speakers look like small coffins sitting
on top of your TV, you'll appreciate Martin-Logan's
Cinema. With its swooping, concave face, it has an
aerodynamic appearance quite unlike any other center
speaker. The Cinema and its big brother, the Logos,
are also the only models in the MartinLogan line that
use a conventional dome tweeter to handle highs. Below
3.5 kHz the Cinema's 27-inch electrostatic panel kicks
in, and it crosses over at 300 Hz to a pair of 5.25-inch
woofers mounted in separate sealed subenclosures at
the speaker's left and right ends.
I set up the MartinLogan
system in Sound & Vision's home theater testing
facility, a 36 x 18-foot room with a 12-foot ceiling.
Since that's on the large side, I was worried at first
that the relatively diminutive MartinLogan speakers
wouldn't be up to the task of filling the space with
sound. Happily, that wasn't the case. Still, as I already
mentioned, the system really needs a subwoofer, particularly
in a medium to large room. For my evaluation I paired
it with B&W's ASW 3000 ($1,500), a 300-watt powered
sub with a 15-inch driver that can pump out some serious
bass.
Before I plugged in the
B&W, however, I spent some time listening to the
Scenarios alone, without a sub. On The Hidden Treasure,
a piece for string quartet from a CD of works by the
contemporary British composer John Tavener (Byzantia,
Virgin Classics 45352), I had the opportunity to experience
firsthand the thrilling sense of "presence" that electrostatic
speakers are renowned for. I could hear delicate details,
like the scraping of the bow against the violin strings,
and when the layered interplay between violin and cello
kicked in during the piece's second half, the imaging
was so sharp I felt I could pinpoint the respective
instruments.
On the more complex Angel
from Massive Attack's Mezzanine CD, the Scenarios projected
the song's incredible sense of spaciousness. The nice
balance between the visceral bass layer, the low, breathy
vocals, and the higher-pitched percussion showcased
the Scenario's seamless integration of woofer and electrostatic
panel. But I soon missed the ultra-low bass I know
this song contains. After I introduced the B&W
subwoofer into the mix, dynamics improved quite a bit,
but it took considerable experimentation to find a
volume setting and room placement that let it blend
smoothly with the Scenarios.
"...when
I turned to DVD movie soundtracks, my attention wasn't
drawn to the Cinema speaker's location at all. In every
movie that I watched, the dialogue seemed to float
effortlessly from the middle of the screen itself."
The finely detailed, almost
tactile presentation that I experienced with the Scenarios
was repeated with both the Script surrounds and the
Cinema center speaker, which makes this MartinLogan
system excellent for multichannel music. Listening
to (and watching) Sheryl Crow's live performance of
Am I Getting Through from the DTS Demonstration DVD
#4 (available from www.dtsonline.com), a fine 5.1-channel
music mix save for the disconcerting placement of percussion
instruments hard in the surround channels, I had a
sense of being dipped into the center of the concert
crowd. Crow's raspy voice sounded pleasantly full and
crisp from the Cinema center speaker.
One problem I've noticed
with center speakers is that they sometimes "box in" the
dialogue: you can actually hear the voice being projected
from the speaker location, whether above or below the
TV screen. But when I turned to DVD movie soundtracks,
my attention wasn't drawn to the Cinema speaker's location
at all. In every movie that I watched, the dialogue
seemed to float effortlessly from the middle of the
screen itself.
The Cinema's clear and
coherent presentation was an asset in scenes with a
complex sound mix spread across the three front channels.
In Three Kings, for example, Conrad (Spike Jonze) opens
a car door while being fired at from above by Iraqi
soldiers. On the soundtrack you hear whizzing bullets,
shattering glass, a car alarm, and, underneath it all,
Chicago's radio staple "If You Leave Me Now." Somehow
the MartinLogan trio managed to create order from this
cacophony, preserving the music track's integrity while
rendering the spatial cues of the sound-effects layers.
As the bullets and mortar
really started to fly toward the DVD's end, however,
I noticed a slight amount of dynamic compression during
loud peaks, like explosions and gunshots. Granted,
this occurred only at volumes most people would consider
absurdly loud. My overall impression was that these
speakers should be able to play as loud as needed in
any system with a good subwoofer sharing the load.
Six-speaker systems costing
$1,000 or less have become the mark most manufacturers
are trying to hit lately. In that dog-eat-dog environment,
systems that cost substantially more need to offer
something special in terms of either performance or
aesthetics to justify their price. Even without a subwoofer,
MartinLogan's Scenario home theater system delivers
on both counts. Its unique looks are sure to satisfy
listeners who care about styling, while its hybrid
dynamic/electrostatic design yields a refined sound
that's a clear cut above what you'll hear from your
average home theater speakers. If you're in the market
for a serious home theater setup and have a yen for
something different something special this MartinLogan
system is sure to satisfy you.
