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 ra- dial driver coupled with a conventional forward firing driver and a planar ribbon tweeter. This combination of Radial and Conventional drivers gives the RL-3.0s the benefits of both designs. The canted horizontal radial driver ensures a huge co- herent sound stage while the conventional forward firing driver adds a midrange presence that is hard to argue with. Unlike its 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 speak- ers 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 re- sponse. You will hear that these speakers are unusually fast. In fact, unlike your average audiophile speaker of less efficiency, the RL-3.0s 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 1000s of hours of listening with the goal of having a near perfect audiophile loudspeaker.

GETTING STARTED After unpacking your speakers, please check for damage. Save your shipping cartons and remember how the speakers were packed in case you have to send them back. HOOKUP Your RL-3s have 3 sets of binding posts. The lower horizontal set is the main jacks that hook to your amplifier. The top vertical sets are as follows: Left set is for the tweeter capacitor. Right set is for the tweeter resistor. These speakers can not be bi-wired. Periodically check the top vertical sets to be sure they are always tight. The tweeter capacitor was externally mounted so that you can easily change from on brand of capacitor to another. Since no two brands sound alike it is possible for you to voice your tweeters to your own liking with different caps. The tweeter resistor is used for attenuation and is also externally mounted so that you can easily change the resistor to a different value. These a 5 watt ce- ramic resistors and can range in value from 1 ohm to 16 ohms or higher. The higher the value used, the quieter the tweeter will become. It is also acceptable when no attenuation is needed to replace this resistor with a straight piece of wire.
