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 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 loudspeakers.

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.



Featuring our inverted cone driver, time aligned to a isodynamic planar ribbon tweeter.


Radial wavefrontsOVERVIEW
 
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 does not change.  It 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 vise for his head on the listening chair!

And best of all the Decware Radials will do it in virtually ALL 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




UPGRADES

The ERRx use the finest components available and no further upgrades are possible.

OPTIONAL FINISHES

The Decware ERRx's come in natural Cherry with a furniture grade lacquer finish as shown above.  The cherry darkens with age...  usually up to 4 shades over the course of a few years and then stays that way. 
 
Custom finishes are Natural Oak, Walnut, Maple, Cherry, Mahogany, and Exotics. 

Shown below is Natural Maple with Painted Corner Posts.  Corner Posts can be painted Black, Silver, Red. 




Example of Customization. Shown in Natural Maple with Silver Accents




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.




Example of Customization.  Shown in Natural Maple with Red Accents



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.



BI-AMPING

Perhaps 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.
