Stack Your REL Subs and Thrill to Maximum Low Bass Width, Depth, and Height
In the real world, bass possess width, depth, and height. In order to experience the proper perspective and height of sonic events in music and home theater, the new S/812 and S/510 subwoofers from REL Acoustics allow you to stack up to three subwoofer units per side into a Line Array (stereo or home theater main L-R speakers) using REL Line Array Connectors. This elevates reproduction from conventional stereo or theater to a truly thrilling floor-to-ceiling panoramic, full scale perspective. You will marvel at the transformation of music and film into the full-scale representation that REL Line Arrays uniquely deliver.
How to Stack Serie S Subs
To render connectivity simple, Serie S subwoofers provide both inputs and outputs for all connections. Thus, a stack of Serie S subwoofers can be connected using only one high-level main cable from power amp to REL stack. In a .1 film sound configuration each channel will require a single main .1 cable as well, but additional units .1/LFE connections in a tower may be daisy chained to minimize clutter.
This connectivity allows for the same amplifier output signal to easily feed multiple sub-bass systems. Simply use the four-conductor cable (REL Line Array Connector, Speakon-to-Speakon) to connect from the HIGH LEVEL OUTPUT of the first Sub-Bass System to the HIGH LEVEL INPUT of the second unit.
When daisy chained, each sub-bass system retains its autonomy and each will need to have its output level, crossover point, phase, etc. adjusted individually. For multi-channel home cinema systems, the same procedure is followed except a RCA-to-RCA cable is also used to connect the first sub-bass system .1/LFE OUTPUT to the .1/LFE INPUT of the second unit. As is typical for REL, both high-level and .1/LFE inputs can be used together and adjusted independently offering the ability to blend both signals to your taste.
Secure Cabinet Coupling
The rails on each Serie S sub have a soft felt pad to protect the finish on the cabinet below. Metal RELcouplers are included in your S/812 and S/510 subwoofer packaging to secure each sub to the sub below safely. These are made of thick aluminum and lock the subs together using hardware provided. The fasteners require a 6 mm hex wrench to tighten.
We strongly advise purchasing furniture restraints from a quality supplier to anchor stacks of Serie S subs to a wall. Use a quality furniture restraint made of nylon webbing or braided steel cable. Please follow the instructions of the restraint you choose and anchor to a structural portion of a wall.
