Designed for Excellence
The added internal volume gives drivers greater freedom and amplifiers improved efficiency, while updated internal bracing keeps cabinet resonances firmly under control. Subtler touches also make a difference, badges that disappear into the grille cloth, silver accents that rest quietly within the cabinet plane, and model numbers etched discreetly into the front rails, visible only when stacked in a Line Array.

Drive Faster. Drive Better
The new S/550 10” high-amplitude driver has been completely rebuilt—only the cast frame remains. Its CarbonAlloy™ cone, capped with pure carbon fiber, sharpens attack and smooths decay, letting notes fade naturally into silence. A redesigned suspension allows greater travel, easily handling the amplifier’s added power.

Amplified Excellence
Rated at 550-watts, the Pure Class D amplifier outpaces its predecessor – but numbers tell only part of the story. In our lab, this unit delivers 600-watts continuous with no strain for extended periods of time, not simply for an instant. Its crest power is fully 50% more than its predecessor. It delivers the fast, truly deep bass Serie S is known for, performance that defies spec sheets. Premium polypropylene capacitors, like those used in our Reference models, were installed in our  input filters resulting in a more open soundstage with greater transparency. We know from extensive experience that this unit is a rugged and reliable amplifier. As always, fed by our second generation PerfectFilter™, the deep bass is utterly remarkable for a subwoofer whose footprint is so tidy.

Analog Filtered to Perfection
We choose analog because it is the only way to achieve truly natural sound. All REL input filters are 100% analog—among the fastest ever offered in a subwoofer. At the core is our renowned High Level Input, which connects directly to the speaker outputs of your main amplifier. This doesn’t draw power; instead, it carries the full sonic signature of your system, allowing REL to blend seamlessly with your speakers—a quality reviewers have praised for decades.

For systems where High Level isn’t possible, our low-level input uses the same analog filter circuit, available via both RCA and XLR connections, to deliver the speed, naturalness, and integration REL is known for. And in theater or dual-use systems, REL uniquely allows High Level and .1/LFE to run together—so music benefits from natural integration, while movies deliver the full impact intended by the mix.

Wired For Sound…Wirelessly
Sometimes the best wire is no wire. Quality cables are a given in high-end audio systems, but there are occasions where it is impractical, unsafe, or unsightly to drape a cable across the room. REL delivers the ultimate solution with Airship Direct™, our optional wireless system that transmits wide-bandwidth, compound signals, carrying both High Level and .1/LFE simultaneously. Even with the scale and output of S/550, Airship Direct™ preserves the speed, transparency, and authority that define REL. It allows seamless transitions between music and movies without ever touching the controls, all from a single module that plugs neatly into the rear panel and stays invisible in your room. Simple, direct, uncompromised: Airship Direct™.
