Congratulations on your purchase of the RL-3.0 loudspeakers! Please
take a moment to read this setup guide so that you understand how this
speaker works.

DESCRIPTION

The RL3 is a 2-way loudspeaker that features the unique Decware 6.5 inch ra­dial driver coupled with a conventional forward firing driver and a planar ribbon
tweeter.

This combination of Radial and Conventional drivers gives the RL-3.0’s the
benefits of both designs. The canted horizontal radial driver ensures a huge co­herent sound stage while the conventional forward firing driver adds a midrange
presence that is hard to argue with. Unlike it’s sister, the RL-1.5, the RL-3.0
has more accurate front to back imaging that is true to the recording. It has
the ability to project an image in front of the speaker plane when needed
whereas the RL-1.5 design keeps the image at or behind the plane of the speak­ers at all times.

Both the Radial and conventional drivers are wired in parallel with no crossovers
of any kind. The lack of a crossover greatly reduces phase shifts throughout the
frequency response, maintains the high efficiency and most of all transient re­sponse. You will hear that these speakers are unusually fast. In fact, unlike
your average audiophile speaker of less efficiency, the RL-3.0’s will have a more
accurate linearity to that speed. That simply means they will be as fast in the
bass as they are in the midrange.

The only crossover in the speaker consists of a single capacitor for the tweeter
which is externally mounted for those who like to tweak.

This 3 component driver array is close coupled and time aligned in a small cube
that is de-coupled to the main cabinet. This expensive process keeps cabinet
resonance away from the array to improve coherency.

In the bottom of the cabinet there is an 8 inch passive radiator that is used to
create a 4th order reflex cabinet without the signature of a tuned port. This
passive driver couples the bass directly to the floor in a radial pattern not unlike
the radial driver on the top of the cabinet.

The pyramidal shape of the cabinet eliminates all parallel surfaces which reduce
standing waves inside the cabinet.

From a design aspect you have a speaker using the more expensive and less
common design elements. It has evolved from 1000’s of hours of listening with
the goal of having a near perfect audiophile loudspeaker.
