Know before you buy
The High Level Input connects directly to your main amplifier's speaker terminals, allowing the subwoofer to receive the exact same signal as your main speakers. This ensures the bass character perfectly matches your speakers' sonic signature for a seamless, natural integration.
Yes, it is designed for dual-use. You can connect it to your stereo system via the High Level Input for music and simultaneously connect your home theater processor to the dedicated LFE input for cinematic effects.
The optional REL AirShip Direct system is designed specifically for high-performance audio, utilizing a zero-compression wireless protocol. It maintains the speed and dynamics of a wired connection without the clutter of cables.
The 12-inch carbon fiber driver is exceptionally stiff and lightweight, which allows it to start and stop with extreme precision. This results in tighter, faster bass response and greater tonal nuance compared to traditional paper or plastic cones.
The passive radiator works in tandem with the active front-firing driver to extend low-frequency performance. It allows the subwoofer to reach deeper into the sub-bass frequencies—down to 19Hz—while maintaining a compact chassis size.
Yes, the Carbon Special supports Line Array configurations. Stacking units vertically creates a larger sound source that better mimics the way low frequencies propagate in a real acoustic space, resulting in a more effortless and authoritative sound.
