THESE ARE OMNI-DIRECTIONAL SPEAKERS
Featuring an
unobstructed
true
radial wave front
for simply insane imaging!
MEET THE QUADRATIC THEORY
PRIME 13 DIFFUSER
PANEL SIZE: 24 x 24 x 3.5 INCHES
This odd looking panel shown above is what it takes to make conventional speakers create a 3D sound stage in most listening rooms.
You need between 6 and 9 of these panels on the front wall between your
speakers - 6 of these panels on each side wall at the first reflection
point, and 9 more panels on the rear wall...
Treating your room with 30 of these ugly diffusion panels is the only way
to hear the full imaging potential of virtually all conventional
loudspeakers.
The ERRx is not a conventional speaker, so the wall reflections are
already diffused to the point where adding this additional diffusion does
nothing. The results obtained with the ERRx speakers is
holographic imaging in untreated rooms... saving you the burden of expensive and ugly room treatments.
If you want to experience the out of body euphoria Steve writes about in
his "middle of the night bloom" articles, you can now have it without
diffusers on your walls - by simply owning these beautiful radial loudspeakers.
 Featuring our inverted cone driver, time aligned to a isodynamic planar ribbon tweeter.
 OVERVIEW
The
picture
at
the
right
is a top down view of the radial
wave-fronts that these speakers create.
The white spot represents
the listening chair.
As you can see, even off center the listener has a perfect stereo
image. The sweet spot is larger than the distance between the
speakers so they sound great anywhere on the couch - or the room for
that matter!
OUTRAGEOUS IMAGING
You can have these speakers 4 feet apart or 14 feet apart and the sound
stage remains larger than your room
boundaries with no holes.
Imagine not
having to worry about exactly where you place the speakers.
Imagine having
better image focus, depth, width and height than your neurotic
buddy with the tape marks on the carpet, tons of quadratic diffusers
all over the walls, and a head vice for his listening chair!
And best of all the Decware Radials will do it in virtually most rooms,
large or small, including yours and without additional room
treatments!
The eight inch radial driver couples to a plinth loaded passive radiator in the bottom for deep bass.
ON THE
SOUND
& PERFORMANCE
These
speakers
work
very
well
in
both
near
and
far
field
applications
in
both
large
rooms
and
small.
We
assume
by
now
you get the great imaging part
but how do they sound? Fast. Articulate. Detailed. Smooth. Organic. Timbres
and room ambiance are rendered unusually well. No sub required.
Shown in set up out in the middle of the room, these speakers also work well close to walls
CROSSOVER - RECOMMENDED POWER
The ERRx is a 2-way loudspeaker that employs a minimalist crossover
network. Time-alignment between the two drivers is done with
placement on the enclosure vs. additional capacitors and networks in the crossover.
The near absence of a crossover makes the ERRx ideal for low power tube
amplifiers. We are able to power these speakers to a modest
listening level with a single 2 watt per channel triode amplifier.
6 watts per channel or higher is however recommend for larger rooms over 150 square feet.
HIGH FREQUENCY ADJUSTMENT RESISTOR
The
ERRx features dual 5-way binding posts on the rear of the
cabinet. The bottom set power the radial driver, the top set power
the planar tweeter. When using a single amplifier, the two sets
of posts are connected together with a piece of wire on the negative and
a resistor on the positive.
The resistor is used to adjust the volume of the planar tweeters for a
given room, which is why it's external. Higher value resistors
create more attenuation while lower value resistors create less.
The range is 1 ohm to 16 ohm (typically) and in plush rooms the resistor
can sometimes be omitted entirely and replaced with a piece of wire.

HISTORY
OF
REVISIONS
A picture of the original Radial Loudspeaker prototype 1/15/2000
|
The
original model RL-1 - Released in 2001
Cabinet bottom open to floor. Bass adjusted with spike length. Updated radial driver design.
|
|
Model RL-2 - Released in 2003
Conventional driver located in the bass, used as a passive
radiator. Bass adjustment came from shorting voice coils of
passive driver with resistors. Updated to a planar tweeter.
Updated radial driver design.
|
 |
Model RL-1.5 - Released in 2005
Passive radiator designed bass with adjustable
spikes for bass adjustment. New tweeter location and bracket.
Updated radial driver design.
|
|
Model ERR - Released in 2009
New cabinet design with passive radiator in bass now pre-loaded into a
heavy plinth. Removable Cloth Grill replaced round metal grill on
all prior models.
Updated radial driver design.
|
|
Model ERRx - Released in 2013
New cabinet design featuring solid hardwood corner posts eliminates the need for a grill.
Updated radial driver design.
