Working with a partner, one in the listening posion and one at the REL manipulang the controls, is the
most effecve and efficient way to set up the REL. If working alone, the inial steps in the set-up can be very
effecvely carried out from the locaon of the REL. Trying to ignore all other music in the track, listen for
the bass drum and its effect on the listening room.
Phase Orientaon: Once in the corner phase can be adjusted. This may be the single most crical step, and
because it really is quite simple, it is oen over-thought. Keep in mind; the right phase is whichever posion
is the loudest or fullest. While playing music with true low bass, adjust the crossover to a point where the
REL and the speaker are sure to share frequencies (about halfway up, or at 12 o’clock on the crossover
control, or slightly higher for smaller speakers). At this point turn the HI/LOW LEVEL control up so that both
the REL and speaker are roughly equal in volume and then switch, using the phase switch, from “0” to “180”
phase posions. Again, whichever posion is loudest or fullest is the correct posion. That is, when the
posion is working in harmony with your main speakers, reinforcing bass, not cancelling it.
Placement: The next step is to determine precisely how far from the corner the sub should be placed
to achieve the most efficient output, as well as the lowest frequency extension. With the REL fully into the
corner, and poinng straight out along the diagonal coming out of the corner, connuing to play the music,
slowly pull the REL from the corner on the diagonal, equidistant from both side and rear wall. At a certain
point (somemes a maer of only a few inches, in rare cases a foot or more) the REL will audibly go lower,
play louder, and, if it truly locks on to the room and is fully pressurizing it, the air around the REL will seem
to be energized, stop right there! This is the correct posion from the corner for the REL.
Crossover and Level Sengs: To determine the crossover point, take the volume of the REL (using the
HI/LOW LEVEL control) all the way down, and put the crossover to 30 Hz. At this point, bring the REL’s volume
back up slowly to the point where you have achieved a subtle balance, i.e. the point at which you can hear
the REL even with the main speakers playing. Now, bring the crossover point up unl it is obviously too
high; at this point bring it down to the appropriate lower seng. For all intents and purposes, this is the
correct crossover point. Once this stage has been reached, subtle changes to volume and crossover can be
accomplished to provide the last bit of complete and seamless integraon. With that, set-up is complete.
