REL T/5x Caisson de grave

The Subwoofer That Changed Everything, Reimagined

No model in REL's long history has sold more units nor engendered more affection than the T/5. Now reimagined in a modern, elegant new form factor, the T/5x's mission remains the same: make remarkable bass far beyond its modest size, do so in a way that complements every interior's style, and eliminate all visual distraction. Mission Accomplished.

Listening Impressions

Connected at high level via the supplied Neutrik Speakon cable, the T/5x integrates into your system with disarming naturalness. Bass arrives fast, precise, without the slightest artificial "subwoofer" effect. On music, it enriches the foundation, adds weight to voices and texture to instruments without ever overwhelming. On films, the impact is immediate. This small cube genuinely changes how your room sounds. And for the doubters: a pair of T/5x units takes the experience into an entirely different dimension.

Key Features

• FibreAlloy™ 200mm Driver: Long-throw aluminium/paper composite cone, inverted alloy dust cap, steel chassis. Light enough for detail, stiff enough for deep bass.
• Down-Firing Design: Bass energy strikes the floor and spreads uniformly throughout the space — the T/5x performs like a larger model.
• 125W Class A/B Amplifier: RMS power with key improvements to transparency and control over the previous generation.

• Arrow Wireless Compatible (optional): REL zero-compression wireless system, single large-scale integrated chip — no quality compromise.
