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.

- 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.
