REL Line Array Connectors for Serie S Subwoofers
These are a pair of Speakon-to-Speakon jumper cables for stacking REL subwoofers into a Line Array. REL sells them as Bassline Blue Line Array Connectors, and its part name lists the S/812 and S/510.
REL builds them for vertical stacks of Serie S and Reference models. They keep the wiring in a tall stack clean and organized.
One Cable From Amplifier to Stack
The connectors daisy-chain the subwoofers in each stack. Only one high-level cable runs from your amplifier to the bottom subwoofer. The jumpers then feed the signal up to the units above.
Neutrik Speakon, Made by Hand
Each jumper uses top-quality Neutrik Speakon connectors. REL hand-makes them with premium materials and pure silver solder. REL also calls them a cost-effective option for multi-subwoofer systems.
Why Stack in a Line Array?
REL points out that in the real world, bass has width, depth and height. Stacking up to three units per side gives music and film a floor-to-ceiling, full-scale perspective.
How Line Array Connectors Fit Your System
Each jumper links one subwoofer's high-level Speakon output to the high-level input of the next sub up. REL says a pair is required for each vertical level of the stack in a stereo setup.
They do not replace the main high-level cable from your amplifier. They are made for REL Serie S and Reference stacks, so check that your model supports Line Array stacking before you order.
Who Are These Cable Accessories Best For?
- Serie S owners building a Line Array — link each stacked subwoofer to the one below it.
- Stereo stacks — REL says one pair is needed for each vertical level.
- Tidy installs — one amplifier cable per stack keeps wiring clean.
- Multi-sub systems — REL calls them a cost-effective option.
- Not for — a single subwoofer; you only need these when stacking.
How Does It Connect to Your System?
- Run one high-level cable from your amplifier to the bottom subwoofer of each stack.
- Connect a jumper from the bottom sub's high-level output to the next sub's high-level input.
- Repeat for each level of the stack, up to three subwoofers per side.
- Sold as one pair (two cables).
