No.36 continues REL’s tradition of redefining the leading edge of deep bass performance. Its 1,000-watt RMS Class AB/D amplifier gives the legendary 15-inch Reference driver the speed, control, and reserves needed to move from the finest spatial detail to breathtaking scale without strain.

The result is not simply greater output. Music gains natural weight and dimensionality. Film moves effortlessly from silence to impact. The soundstage opens, dynamics feel unrestrained, and the entire system performs with greater ease.

No.36’s curvilinear cabinet is unique within the REL range, a design lineage that began with the original Gibraltar and reflects lessons John Hunter absorbed from his mentor, legendary Italian designer Franco Serblin. Its continuous curves are extraordinarily difficult to execute, particularly where the top surface tumbles gracefully into the rear corners. Inspired by the sweeping forms of classic wooden runabouts, the shape is more than beautiful; it reflects a longstanding REL belief that cabinet form, rigidity, and sound are inseparable.

Every visible detail reinforces that form. The sculpted grille follows the cabinet’s curves rather than interrupting them, its taut strings revealing rather than concealing the architecture beneath. Carbon fibre, used throughout No.36 for its performance properties, becomes a visual signature as well, framing the triple-plated badge and connecting the exterior design to the engineering within. Triple-plated stainless-steel handles inset into the cabinet provide another jewel-like detail while anchoring securely into thick plates of milled aluminum. Twelve coats of hand-rubbed lacquer complete a surface of exceptional depth and permanence.

To meet the demands of No.36’s 1,000-watt RMS Class AB/D amplifier, the cone structure has been reinforced and the suspension revised to permit greater travel while maintaining control. Carbon fibre locking shells and larger full-ring terminals transfer the immense current available from the amplifier with complete confidence.

No.36's 1,000-watt RMS Class AB/D amplifier was developed to give its 15-inch Pure Carbon Fibre driver extraordinary reserves of speed, control, and dynamic freedom. It delivers immense current precisely when the performance demands it, then settles instantly as the music returns to silence.

Its efficiency allows No.36 to deliver breathtaking scale without the excess heat and power consumption associated with a conventional amplifier of this output. More importantly, it maintains composure at every level, preserving texture, timing, and spatial detail even during the most demanding passages.

For more than two decades, REL Reference Line Arrays have represented the ultimate expression of our approach to deep bass. No.36 advances that tradition with greater current, increased driver capability, and a more rigid, precisely adjustable cabinet, delivering deeper extension, greater drive, and increased output from every unit.

But a Reference Line Array is about far more than output. By vertically distributing multiple subwoofers through the height of the room, the array energizes the space in a fundamentally different way, allowing the main loudspeakers to perform with greater freedom and scale. The transformation extends beyond bass: the soundstage opens, dynamics become more effortless, and midrange and high-frequency performance gain clarity and dimensionality.

Optional AirShip Direct delivers REL’s renowned High Level Input and .1/LFE signals wirelessly, with zero digital compression and no compromise in sound quality. High Level and .1/LFE can be used simultaneously, allowing No.36 to integrate seamlessly for music while delivering the full impact of film soundtracks, without the need for long cable runs.

The REL Reference Remote is designed with the same attention to detail as No.36 itself. Its sculpted form sits naturally in the hand, while its substantial weight and beautifully finished controls convey the quality and permanence expected of a Reference product.

More importantly, it places every critical setup control exactly where it belongs: in the listening chair. High Level or Low Level gain, crossover, .1/LFE gain, phase, and Dual Parametric EQ can all be adjusted while listening to the system. Once setup is complete, the remote can be switched off to lock the settings and prevent accidental changes.
