User Manual

REL products are not tradional subwoofers, but 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 15Hz.

Therefore, for the moment, please 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 posioning

diers from convenonal subwoofers. A REL will take advantage of physics and room acouscs to provide

deep pressurizaon as no tradional subwoofer can. It is important that you bring to the set-up process a

willingness to do things a lile dierently in order to obtain these superior results. The end result of your

labors will be an uerly seamless integraon 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 een minutes to accomplish once connected.

Two Things 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 connecon is made using the supplied 33’ 6” (10 meters) cable, the bare leads

of which connect to the speaker output terminals of the power amplier. The easy and foolproof connecon

at the REL is done with a Neutrik® Speakon® connector. The purpose of connecng to the speaker output

terminals is one of the unique secrets of REL’s success. By connecng to the High Level input on the REL

from the amplier, you build forward the sonic signature of your main system, including the tonal balance

and ming cues of the enre 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 pressurizaon with RELs. Low bass pressurizaon below 40Hz is best derived

from corner placement, where the most linear and ecient low bass can be produced because the

subwoofer is able to take advantage of the tangenal (corner-to-corner) axis which is typically the

longest axis in a room.
