Merely 28 inches
tall, this beautiful fabric wrapped
speaker features a solid walnut top
and bottom, a single 5 inch
crossover-less driver, and get
this...
It covers the full
9.96 octaves of human hearing!
And while the
driver is rated at around 90dB
@ 1 watt /1 meter, that actual
efficiency in this cabinet
design is closer to 93/94dB
making it compatible with high
quality tube amplifiers as
small as 2 watts.
This seemingly
impossible stunt of getting
such performance from such a
small cabinet is made possible
by one of DECWARE's creator
Steve Deckert's original
designs.

THE
DNA HORN DESIGN (C) STEVE DECKERT /
DECWARE
The DECWARE DNA HORN FLARE
BESIDES HAVING
REAL BASS, The DNA horn does a
few other things that are
foreign to most single-driver
full-range speakers...
- DNA's
have
remarkably
flat frequency response -
it's not tipped up or
rolled off.
- DNA's
do not shout, and have no
glare. They are however
extremely detailed.
- DNA's
image
with
world
class
showmanship
and
create
an
immersible
and
deep sound-stage because
they can be pulled out
into the room. They do not
require the room corners
for bass reinforcement.
- The
DNA's
horn
flare
creates
output
from
around
23Hz to 5kHz with an approximate
6dB slope. This means that
the output of the horn
flare is putting mid-range
frequencies at -30dB with
a continuing slope
graduating to -60dB at
around 18K. This is
an ideal response for
ambient enhancement
without risk of damaging
the focus of your sound
stage.

THE DNA
DRIVER
A
fantastic single driver
loudspeaker owes a
lot of it's sound and
performance to the driver
used. With no other
drivers and no crossovers it
leaves much of the burden
of success on the driver
itself. So here's a
bit about the driver we
used:
Markaudio Alpair 10P-A 6"
Paper-GRF Cone Full Range
From the Alpair Literature:
This Alpair 10P Gen.1
represents a significant
development of Markaudio
Full-range drivers. The
production history of
the Alpair 10 series is
well known inside purist
audiophile circles but
this is the first time
that a paper cone
version has appeared in
the 10 series.
The cone is the most
radical shallow design
Markaudio has produced
for this size of driver.
To maintain its
stability, the materials
used include an
arrangement of glass
reinforced fibers.
The dispersion
characteristic is ultra
wide. The 10P is
frequency range capable
to +25-kHz with an
efficiency of 89.5dB.
These efficiencies were
achieved by considerable
design efforts to reduce
mass. The 10Pʼs power
train under moving mass
conditions is less than
5.2g while retaining
Markaudioʼs “long
throw�? design feature.
The coil winding is
“high stress�? type
forming the tight band
arrangement on its body.
The result is one of the
lightest coils deployed
is this size class,
weighing under 2.2g.
The power-train
suspension compliance is
extremely sensitive. It
is capable of large
extension for this class
of Full-Range audio
driver (7-mm 1 way,
limited by the
Arrestor).
The Alpair 10P is a
“purist�? technical
driver. Its purpose is
to serve the audiophile
and experimental
markets. Due to the
highly
emittance-sensitive
power-train, this driver
will need users to take
note of the need for
high quality lower power
amplification and
audiophile level source.
The Alpair 10P should
not be considered as a
“general purpose�?
emitter.
Designer Steve Deckert talking
about...
The DRIVER:
"It's the best driver I've heard
straight out the box with no
modifications. In fact there is
absolutely nothing I can do to it or
tweak on it to make it better... most
impressive!"
The CABINET:
"As you may have figured out by looking
at the frequency response - the secret
to the DNA horn design is that it
stretches bass response down to 1/2 the
driver's fs. This is a good thing
because you get that precious low bass
with the speed of a higher fs driver
that moves less!"
"This speaker
does three things exceptionally
well:
1) It has extraordinary bass extension
and quality.
2) It has world class imaging
capabilities.
3) It has unusually flat and smooth
frequency balance."
It can do all of it with just a couple
watts.
