Do not place on a stand or table; it may fall causing injury to a child or adult, and damage to the unit. The unit should only be operated from the power source indicated on the panel of the amplifier. Only use the power cord supplied. Do not allow anything to rest on the power cord.
Welcome to the REL Family Thank you for buying a REL Serie T Sub-Bass System. The Serie T is the result of a state-of-the-art collabora0on between our American design and engineering team and our Bri0sh produc0on team. Serie T is conceived as the most cost effec0ve high end product we know how to build. We have spared none of the materials and finishing techniques our larger designs are noted for.
Overview: Serie T Sub-Bass Systems Many or most loudspeakers emphasize the mid-bass. This is the range from 50 to 90 Hz. We at REL believe this is an incomplete approach and that loudspeakers need to be extended in the lower frequencies for true full range reproduc0on. All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce very low frequencies (below 30 Hz) that are felt rather than heard.

1 Volume Control for .1/LFE INPUT: Use to adjust output level when using .1/LFE input from a 5.1 amplifier or processor. 2 Volume Control for HI/LOW INPUT: Use to adjust output when using either HIGH-LEVEL or LOW-LEVEL input. Do not use both simultaneously. 3 Crossover: Used to select crossover frequency. Variable between 30Hz and 120Hz. 4 .1/LFE INPUT: Used to connect to the .1/LFE output from a 5.1 amplifier of processor.
Connec)ng Up Always switch off your system before disconnec0ng any wires. ALWAYS connect using the REL HIGHDLEVEL input, unless your system simply cannot accommodate this. While rare, a few esoteric systems, such as those that deliver a pure digital signal to ac0ve speakers preclude this possibility. To increase the versa0lity of connec0ng up, the Serie T models have three separate inputs. A Neutrik Speakon socket and two phono sockets.
main system is carried forward into the Sub-Bass System. This is a very important point and together with REL’s Natural RollOff™ circuitry, ensures far superior system integra0on of the Sub-Bass System with the main system. HIGH2LEVEL INPUT: Connec0ons should be made to the same binding post on main amplifier as the main speakers. Red to amplifier main right speaker red terminal, yellow to amplifier main le! speaker red terminal and black to amplifier main speaker black terminal, right or le! but not both.
REL Set-Up Made Simple REL products are not tradi0onal 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 posi0oning differs from conven0onal subwoofers.
• The standard HIGHDLEVEL hook up procedure is: a1ach the red wire to the amplifier’s right posi0ve speaker output terminal; a1ach the yellow wire to the amplifier’s le! posi0ve speaker output terminal; a1ach the black wire to whichever of the amplifier’s ground output terminals is convenient; plug the Speakon connector into the Sub-Bass System’s HIGHDLEVEL input.
• If connec0ng two RELs in a stereo configura0on, connect the black wire of each REL to the nega0ve speaker terminal of the corresponding amplifier channel; twist together the red and yellow wires of each REL separately and connect each pair to the posi0ve speaker terminal of the corresponding amplifier channel.
• If connec0ng a REL as a dedicated rear channel sub, connect the black wire of the REL to either the le! rear or right rear nega0ve speaker terminal; connect the yellow wire to the le! rear posi0ve speaker terminal; connect the red wire to the right rear posi0ve speaker terminal. Supplied Neutrik Speakon HIGH-LEVEL Interconnect Yellow Black Red + RL – + RR – Amplifier Main Speaker Outputs LOWDLEVEL connec0on (via phono connector) is always an op0on if HIGHDLEVEL connec0on is not possible.
Working with a partner, one in the listening posi0on and one at the REL manipula0ng the controls, is the most effec0ve and efficient way to set up the REL. If working alone, the ini0al steps in the set-up can be very effec0vely carried out from the loca0on 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.
Hint: There may be a tendency to set the crossover point too high and the volume of the Sub-Bass System too low when first learning how to integrate a REL with the system, the fear being one of overwhelming the main speakers with bass. But in doing so, the resul"ng set-up will be lacking in bass depth and dynamics. The proper crossover point and volume se#ng will increase overall dynamics, allow for extended bass frequencies, and improve soundstage proper"es.
2 In the rear corner (ideally that which is opposite the primary sub), connect a second REL to the rear speakers using REL Theater Reference connec0vity. The purpose of the rear channel REL is to ensure proper front-to-rear balance and weight; too o!en virtually ALL the power and weight in a theater comes from the front and it produces unnatural weigh0ng as well as hot spots.
When you have accomplished this task, plug all three units in and re-check your gain se2ngs as the cumula0ve effect of hooking all three up will usually result in, temporarily, excessive output. Work carefully and methodically to reduce the se2ngs on primary, then rear, and finally center channel RELs and in a few minutes balance should be restored.
Power Saving Efficiency All REL Sub-Bass Systems are designed for maximum power efficiency, both when passing a signal through to its resultant output sound into the room and also when silent. REL circuitry allows for “power starva0on” opera0on under no signal condi0ons.
