Classic 99 – A Combination of Design, Power, and Grace

The Rel Classic 99 subwoofer builds on the excellent results achieved by the Classic 98, which revived the vintage classic in the subwoofer category. However, this Classic 99 is 40% larger in volume and features a new 450-watt Class D amplifier with PerfectFilter™, all-analog, driving a robust 30 cm (12-inch) pulp cone driver with a full 51 mm (2-inch) of excursion that radiates directly into the floor. The cone, made of multiple layers of hot-pressed pulp, is lightweight for maximum speed of movement yet rigid enough to prevent warping at high power. The cabinet features 32 mm (1.25-inch) thick walls and a natural walnut veneer. All these elements combine to create a deep, bold, and characterful low-frequency sound experience, delivering warm, reliable, and class-leading sound.

The Classic 99 is designed for large rooms, paired with large speakers. The air-suspended cabinet, floor-firing woofer, and high power output simplify room installation. The Classic 99 can also be connected wirelessly with REL's Airship II or HT-Air MkII technology (optional).

Construction Technology

The Classic 99 uses a 30cm floor-firing woofer, constructed using the traditional paper cone technique. Lighter, hot-pressed paper forms the outer two-thirds of the cone, while the internal inverted dome is made of a higher-quality, air-dried paper, which stiffens the speaker, allowing the Classic 99 to outperform many past products. The natural butyl surround smoothes the dynamics, maintaining their consistency over time. This driver was designed to handle the abundant power delivered by the internal amplifier. In the 1990s, offering a 450W amplifier at an affordable price was a virtually impossible challenge. Today, with current technology, REL has only leveraged one of its most recent amplifier designs: a high-current, lightning-fast Class-D amplifier. This results in a sound that is not only powerful, but also high-quality and deeply impactful. While retaining the aesthetics of the historic models, the Classic 99 sounds louder and deeper, offering an audio experience that combines the reliability and technology of modern RELs with a retro look and sound.

Connections and Functions

REL has always offered a generous number of connections. High-level, low-level, .1/LFE, all with their own volume control and variable crossover frequency. There is also the option of varying the phase 0/180°. Furthermore, purely analog LimitLess™ and Perfect Filters™ are used on the input, ensuring that the Classic 99's amplification is a harmonious blend of modern and vintage.

Wireless

REL is also now renowned for its wireless connection technology, which preserves dynamics without any compression. For the Classic 99, you can choose between two wireless models based on your needs.

AirShip II is the most advanced, designed for REL's Reference models. It operates at 5.8 GHz and supports both high-level and .1/LFE connections, even simultaneously.

HT-Air MKII always transmits at 5.8 GHz and supports low-level or .1/LFE stereo connections. High-level connectivity is not supported.
