“The dARTS system … provides an
eye-opening glimpse at what I think
will prove to be the future of
loudspeaker system design.”
Chris Martens,

Uniform Sound for Every Room™
In 1990, Phase Technology foresaw that the future of audio would morph into active
digitally amplified speakers with complete DSP (digital signal processing) control over
their performance. After fifteen years of research and development, with countless
trials, this dream has been realized with the introduction of dARTS™ (Digital Audio
Reference Theater Systems). dARTS is the world's first sound reproduction system
with predictable results in the lab and in your room.
dARTS Meets The Challenge - Two separate, but equally important challenges have
long been recognized when building a world-class home theater or music system.
First, all the speakers in a system must be able to create lifelike dynamics and be
perfectly matched to produce a seamless and enveloping soundfield in the room. When all
speakers ARE exactly matched, you'll hear just what the director intended as planes fly by
overhead, as bullets whiz from one corner to another, and as characters walk across the
screen as they talk.
The second challenge is the room itself. No matter how good (or expensive) a speaker
is, it will sound different in ever y room. Walls, furniture, and other objects reflect and absorb
the sound from your speakers, creating a sonic fingerprint, specific to your room.
The System - Phase Technology has put its 50 years of experience in designing and
building high-performance speakers to the ultimate test in the dARTS project. Knowing that
we needed to be able to perfectly match a complete multi-channel home theater system's
speakers, we set out to engineer all-new drivers, utilizing manufacturing tolerances much
tighter than any previously employed. We also needed the amplifier to have very high output,
"Phase Technology’s dARTS is
without a doubt, one of the
best systems I’ve heard."

and include powerful DSP engines to allow us to control all of the various parameters of the
speakers. We accomplished this with the development of the DP-2000, a completely new
digital/programmable amplifier.
The DP-2000 digital/programmable amplifier manages the entire system with 16
channels of DSP and amplification. Each channel controls the crossover, time alignment,
equalization and delivers 250-watts of amplification to each individual driver (woofer,
midrange, and tweeter). Each subwoofer has its own internal 500-watt amplifier. To keep up
with the resolution and dynamics of the amplifiers we designed all new woofers made of a
three layer composite of glass fiber/nomex honeycomb/glass fiber, which is very light yet
extremely rigid. By using digital control in a bi- and tri-amplified configuration we are able to
achieve previously unreachable levels of accuracy and per formance.
Each dARTS system is custom-programmed, and leaves our factory software-tuned
with each speaker matching a target response curve, and each other, within an inaudible
+/- 0.5dB.
The Room - In order to have predictable results in any room we partnered with Audyssey
Laboratories, who invented a computerized system called MultEQ XT. MultiEQ XT analyzes a
room's acoustics from multiple locations and based on the measurements, calculates an
equalization solution that corrects for both time and frequency response problems

throughout the listening area. This is the first viable solution for equalizing multiple seating
areas and having them all sound virtually the same.
The Installation - When your trained dARTS installer sets up the dARTS system in your
room, he uses his laptop running the MultEQ XT software with a calibrated microphone and
digital interface to measure the acoustic properties of your room throughout the listening
area. The acoustic proper ties of your room are then used to create a set of custom
correction filters which are uploaded into the DP-2000. The result is a sound reproduction
system that's perfectly matched and is restored to its target response curve, just as it was
when it left our lab. This performance can be achieved in virtually any type of room - large
or small, bright or absorbent, open or enclosed - so you are assured of realistic, dynamic
sound throughout YOUR listening area.
The Result - Phase Technology has developed a completely closed-loop system, where we
knew from the very start how the system should sound in your room. Through digital
technology we made it happen. No other manufacturer in the world can provide this amount
of control over the entire process, and the results are clearly audible. Your “sweet spot” now
becomes the whole seating area!
“The dARTS system is the most advanced
I have yet encountered.” Brent Butterwor th,

All of this wonderful technology and sound quality wouldn't matter much if the system
didn't fit into your home's style. Recognizing that, Phase Technology has developed
numerous versions of dARTS systems to match your lifestyle and produce the necessar y
volume levels in your particular room.
There are two different basic sizes of dARTS speakers, a smaller 525 Series built around
5.25” woofers, and a larger 650 Series using 6.5” woofers. Within each family, we offer
three styles of speakers: In-Wall (IW) for discrete flush-mounting, with nothing protruding into
your room; Custom Built-In (CB), which are painted black enclosures suitable for placement
inside cabinets or behind perforated movie screens; and Free-Standing (FS) beautiful cur ved
and angled, high gloss cabinets to make a bold fashion statement in your room.
Since Phase Technology is a vertically-integrated manufacturer, building everything
ourselves, we also offer customization capabilities so our perfectly matched speakers can
perfectly match your listening room too. The CB versions in both the 525 and 650 Series
can be customized in size and shape to fit within odd-shaped spaces. They can also be
increased in size and driver configurations to produce theatrical reference levels in any size
space. The FS 650 Series cabinets can be customized in virtually any veneer or paint finish,
so if the standard piano black gloss lacquer or natural cherry veneer doesn't meet your
needs, it's not a problem. Both sonically and visually, almost anything is possible!
Phase Technology's dARTS systems share similar per formance parameters, regardless of series or style. Each dARTS system will meet its target curve and provide frequency response from 20 Hz - 30 kHz.
All systems use the DP-2000 amplifier (up to 250 watts x 16 channels @ 4 ohms; fully digital control of crossover points and slopes, frequency contouring, time/phase alignment), and Audyssey Labs' MultEQ
XT room correction system. To choose the appropriate system for your room:
525 FS single sub systems will produce a minimum SPL of 105 dB (THX reference level) in a 2500 cubic foot room.
525 CB & IW dual sub systems will produce a minimum SPL of 105 dB (THX reference level) in an 8000 cubic foot room.
650 FS single sub systems will produce a minimum SPL of 105 dB (THX reference level) in a 5000 cubic foot room.
650 CB & IW dual sub systems will produce a minimum SPL of 105 dB (THX reference level) in an 18000 cubic foot room.
