REL revamps Serie S subwoofers with two new models

Subwoofer corp REL has launched two new models in its mid-range Serie S stable, deploying filter-down tech from its reference-level products and introducing a 'stackable' rail design.

The bigger of the two new woofers is the S/812, which features a front-firing 12in ContinuousCast Alloy Cone driver and down-firing 12in carbon passive radiator. The smaller S/510 deploys a 10in active driver (plus 12in passive radiator).

Upgrades over the previous Serie S driver design include rear-mounted carbon fibre bracing to stiffen the cone, while REL says it has also improved the speed and precision of its output via tweaks to filtering.

The S/812 uses a NextGen5 amplifier unit, previously found in its 212/SE, rated in excess of 1,000W peaks. For the S/510, a 500W NextGen 3 amp is used. 'The increased power is needed to handle the special filters first used in our new HT/1508, custom versions of which now tailor the .1/LFE output channel of the new Serie S. These filters result in almost twice the output below 40Hz.'

Both new subs swap out REL's traditional chunky four-corner feet for rails that not only give them a 'floating' appearance, but allow up to three to be stacked vertically via supplied metal plates. 'This new feature will open up REL line arrays to a new audience at about half the price of our Reference Line Arrays.'

Other typical REL features are simultaneous high and low-level connections; both the S/510 and S/812 offer high-level Neutrik Speakon connectors, plus low-level L/R phono, LFE phono input and LFE XLR input.

The subs are available in gloss white and gloss piano black finishes, and are compatible with REL's wireless AirShip connection system.

Pricing is £1,800 for the S/510 and £2,400 for the S/812.

Says REL of its new subs: 'We have overlooked nothing, have approached every detail as fresh, with a singular focus on every possible aspect of performance and design.'
