It’s simple to describe what
Audyssey’s MultEQ XT processing
does in Phase Technology’s dARTS
package. It dynamically adjusts the
speakers’ output so the system will
sound the same no matter which
room you install it in. By itself, that
feat is pretty amazing, but there’s
more to the story. To hear a great
stereo or multichannel image
through most systems, you’d have to
lock your head and your butt in one
listening position. (The music may
move you, but you’d better not
move if you want to hear the music.)
But MultEQ XT expands that single-
seat sweet spot into a shared, multi-
listener experience.

It’s not so easy to explain how
Audyssey does what they do. In
the typical dARTS installation, an
installer takes audio measure-
ments at various points through-
out the listening room. Hecht tells
me that 12 to 14 measured points
are optimal in most rooms, but an
installer can do 32 (or more) if
necessary.The installer then feeds
the numbers into a computer run-
ning a proprietary version of the
MultEQ XT processing program.
The program painstakingly ana-
lyzes the room’s acoustics and, using
512 filters per channel, calculates
the frequency and time changes

The system downloads the data
into memory onboard the dARTS’
unique 16-channel, 250-watts-
per-channel digital amplifier. Each
speaker driver has its own indi-
vidual amplifier channel, and no
passive or analog crossovers are
needed anywhere in the system.
Hecht says this makes Phase

MultEQ XT doesn’t make crappy
speakers sound good. It keeps rooms
from making good speakers sound
crappy. Speaker quality is incredibly
important, and Phase Tech doesn’t
need Audyssey’s, or anyone else’s,
help when it comes to creating
excellent speakers. Having listened
to the dARTS package, though, I
think the 50-year-old company has
outdone themselves this time.

You can get the dARTS system in
one of three flavors: freestanding,
in-wall, or unfinished for a behind-
the-wall installation. I heard the
behind-the-wall version. It’s hard to
believe, but, before any dARTS
package leaves the factory, Phase
Tech matches each and every
speaker’s driver to within
+/– 0.5 decibels of their
reference driver. (Even the
best passive speaker sys-
tems are hand tuned to
only +/– 1 dB.) This
ensures that, once installed,
the complete system
matches the factory’s equal-
ization capabilities to
within +/– 0.5 dB.

As each driver couples
directly to its own digital
amplifier channel, Hecht
discovered that he needed
to design new drivers in order to
take full advantage of the amps’
superior resolution and dynamics.
These include an updated soft
dome tweeter developed specifi-
cally for the system (“the best
we’ve ever designed”), as well as
new woofers that use a three-layer,
