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.

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
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
Link to MarkAudio PDF Enclosure Plans
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 fibres. 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
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
driver that moves less!"
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.
