REL Acoustics Classic 99

Overview

The REL Acoustics Classic 99 is a vintage inspired active subwoofer built around a 12 inch driver and REL's music first design philosophy. It belongs to REL's Classic line, which pairs retro walnut styling and analogue faceplate controls with modern amplification and filtering. The signature feature is REL's high-level Speakon connection, which takes a feed from your main amplifier's speaker terminals so the subwoofer follows the exact character, voicing and timing of that amplifier. The result is a low end that integrates with the mains as one coherent voice rather than a separate box adding rumble.

Under the retro cabinet the Classic 99 uses a substantial down-firing driver and an on-board amplifier with continuously variable crossover, gain and phase controls, giving you the tools to dial the sub precisely into any room. A separate .1/LFE input lets the same subwoofer serve double duty in a home theater system, while the high-level input carries the load for two channel music. The Classic 99 is also compatible with REL's wireless options for a clean, cable-free connection.

This subwoofer is for the listener who wants genuine depth and weight beneath a full-range music system without sacrificing speed or musicality, and who appreciates classic HiFi aesthetics. It suits stereo rooms, mixed music and movie systems, and enthusiasts who may later add a second Classic 99 to run a stereo pair or stacked array for greater output and dimensionality.

How the Classic 99 Compares

REL Classic 99 vs REL Classic 98

The Classic 98 is the step down in the Classic line, using a 10 inch driver in the same vintage inspired styling. The Classic 99 moves up to a 12 inch driver for greater displacement, deeper reach and more effortless output in larger rooms. Both share REL's high-level Speakon connection and music first voicing, so the choice comes down to room size and how much low end weight you want. See the REL Classic 98.

REL Classic 99 vs REL S/550

The S/550 sits in REL's high performance S line with a modern industrial aesthetic and a driver plus passive radiator arrangement aimed at maximum speed and resolution. The Classic 99 pursues a similar musical goal but wraps it in vintage inspired styling with analogue controls. Choose the S/550 for a contemporary reference look, or the Classic 99 for retro character in the same room. See the REL S/550.

REL Classic 99 vs REL HT/1205 MKII

The HT/1205 MKII is part of REL's HT line, optimized primarily for home theater impact through its .1/LFE input and high-output driver. The Classic 99 is designed music first, using the high-level Speakon connection to blend with the character of your main amplifier while still offering a .1/LFE input for movies. Pick the HT model for a dedicated cinema, or the Classic 99 for a two channel system that also handles film. See the REL HT/1205 MKII.

Recommended System Pairings

A subwoofer augments an existing system, so pair the Classic 99 with full-range mains, an amplifier to drive them, and a REL wireless kit or cable for a clean high-level connection.

• Klipsch Rebellion Heritage Bookshelf These vintage styled speakers echo the Classic 99's retro character and reach only so low on their own, so the sub fills in the foundation beneath them beautifully.
• Spendor A1.2 Bookshelf The compact A1.2 has a refined, musical presentation that benefits from the Classic 99 extending its bottom octaves without disturbing its midrange purity.
• Advance Paris A10 Integrated This integrated amplifier drives your mains and provides the speaker terminals that feed REL's high-level Speakon connection so the sub follows the amp's character.
• REL Arrow Wireless The Arrow wireless system offers a clean, cable-free connection between amplifier and subwoofer, ideal when the Classic 99 sits away from the rack.
• REL Bassline Blue High Level Cable This upgraded high-level Speakon cable improves the wired connection for the purest transfer of the main amplifier's signal to the sub.
