PRIME 13 DIFFUSER
PANEL SIZE: 24 x 24 x 3.5 INCHES
This odd looking panel 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 diffuser panels is the only way
to hear the full imaging potential of virtually all conventional
The ERRx is not a conventional speaker, so the wall reflections are
already diffused to the point where adding these diffusers does
nothing. The results obtained with the ERRx speakers is
holographic imaging in untreated rooms... saving you over $6000 not
including labor to ruin the look of your family room by installing these large sound treatment panels.
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.

CROSSOVER - RECOMMENDED POWER
The ERRx is a 2-way loudspeaker that employes 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
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.
the only thing sweeter than a nice low powered tube amp is two low
powered tube amps. Hook one to the lower set of posts to power the
radial driver, hook the second amp up to the upper set of posts to
power the planar tweeter. Adjustment of the tweeter is achieved by
adjusting the gain (volume) of the tweeter amp. A preamp is then
used to drive the pair of stereo amplifiers so that you can raise and
lower the volume of the pair with a single control.

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.
