REL products are not tradional subwoofers, but are true Sub-Bass Systems. A REL is designed to augment
the performance of “full range” speaker systems in order to provide, in certain cases, linear response below
12 Hz. Therefore, for the moment, set aside everything you’ve been taught about subwoofers and how they
are integrated into a stereo or home cinema system. REL Sub-Bass Systems set-up and posioning differs
from convenonal subwoofers. A REL will take advantage of physics and room acouscs to provide deep
pressurizaon as no tradional subwoofer can. It is important that you bring to the set-up process a willingness
to do things a lile differently in order to obtain these superior results. The end result of your labours will
be an uerly seamless integraon of true deep bass to a sound system, regardless of the main speakers’ low
bass capability.
Basic set-up should take no more than ten to fieen minutes to accomplish once connected.
Before You Begin
1 It is helpful to know that you will almost always connect the REL to the input on the rear panel labeled
“HIGH-LEVEL INPUT.” This connecon is made using the supplied 34’, 10” (10 meters) cable, the bare
leads of which connect to the speaker output terminals of the power amplifier. The easy and foolproof
connecon at the REL is done with a Neutrik Speakon connector. The purpose of connecng to the
speaker output terminals is one of the unique secrets of REL’s success. By connecng to the high-level
input on the REL from the amplifier, you build forward the sonic signature of your main system, including
the tonal balance and ming cues of the enre electronics chain. In this way, the REL is fed the exact
signal that is fed to the main speakers.
2 When possible, the REL should be placed in one of the corners behind the speakers. Remember, we are
dealing with true LOW bass pressurizaon with RELs. Low bass pressurizaon below 40Hz is best derived
from corner placement, where the most linear and efficient low bass can be produced.
Connecng and Seng Up
HIGHLEVEL connecon, using the enclosed cable with the Neutrik Speakon connector, is always the first
choice. This connecon can be made without affecng the performance of the amplifier because the REL’s
amplifier input impedance is 150,000 ohms, in effect not producing any addional demand whatsoever on
the rest of your system.
