Critics and
audiophiles agree - the listening quality of the DQ-10 is unexcelled. What
accounts for its superb performance?
Time - Much
credit for its smooth coherence must be given to the precisely matched
transient characteristics of the five drivers. And, a good deal has been
written about the DQ-10 and its
extraordinary solution to the problems of time delay or phase distortion. It is
not surprising that other high quality speaker designers have followed suit in
offering their versions of time delay correction.
… and Time
Again - The real "secret" to the unprecedented performance of the
DQ-10 lies in Jon Dahlquist's patented method for reducing diffraction, a more audible and destructive
form of time distortion. The separate baffle plate on which each driver is
mounted is dimensioned to minimize diffraction in the frequency band in which
it operates. Thus, the effect of the sound we hear is that of a driver mounted
in free space, without obstructions or surfaces to distort the original sound
source.
it can be said that the DQ-10 eliminates
inaccurate reproduction caused by time elements - inertial time delay, and
diffraction time delay - distortions that limit the performance of conventional
speaker systems.
"That's
why the more critical listener will select the DQ-10. Time and time
again".
What
accounts for the superb performance of the DQ-10?
The
precisely matched transient characteristics of its five drivers are one reason.
The rugged crossover, using oversize components and now equipped with mylar
capacitors is another.
But the
DQ-10 reproduces music with unprecedented clarity and spaciousness. The
explanation lies in Dalquists solution to the problems of time delay and
diffraction delay distortion.
Here is the
speaker system that eliminates inaccurate reproduction caused by time elements.
Conventional
Driver Mounting - in a common flat baffle. Smaller drivers have lower mass and
shallower cone surfaces. High frequencies arrive earlier than lower
frequencies, harmonic overtones before fundamentals. This is time delay
distortion.
The
Dahlquist Solution - With Phased Array™ Mounting, drivers are positioned so
that all frequencies (fundamentals and harmonic overtones) reach the listener
at the same time. Musical sound is in phase.
-----------------------------------------------------------------------------------------------------------------------------
Diffraction
Delay Distortion - In conventional speaker systems, sound wave energy radiates
across the speaker baffle to the edges of the cabinet and is diffracted. These
secondary signals create unnatural exponential decay and destroy clarity and
spaciousness.
The
Dahlquist Solution - In the DQ-10, the
staggered baffle plates are sized to minimize diffraction. It is as though the
drivers are mounted in free space with no nearby obstructions to distort the
pure sound source. Sound decays naturally.
Hi-Fi
doesn't have to become "habit-forming". And yet, equipment which
sounds fine when you first purchase it, often sounds "flawed" over
time. Most likely, the equipment doesen't deteriorate - your listening becomes
more acute.
The break
the "speaker-switching habit", select loudspeakers that have
demonstarated their ability to satisfy critical listeners over long periods of
time. The Dahlquist DQ-10's have earned consistent "rave" reviews
from their introduction in 1974 to this date.
You still
may want to upgrade your system in the future, and Dahlquist loudspeakers are
designed to grow with you. The DQ-10's interface perfectly with the Dahlquist
DQ-1W sub-woofer. By using the Dahlquist MX-1 (Passive Matrixing Crossover),
you can add a DQ-1W to your system without requiring an extra amp. With the
Dahlquist LP-1 (Variable Low Pass Filter), you can add either 1 (mono) or 2
(stereo) DQ-1W's as part of a bi-amplified system.
