    The brand new flagship REL No. 25 reference subwoofer commemorates and celebrates a quarter century of building the finest sub bass systems, while pointing to the future and the next 25 years as it employs RELs most advanced design, engineering and craftsmanship.

    No. 25 combines the power of an ultra-reliable 1,000 watt amplifier, with a lightweight and perfectly balanced carbon fibre 15” driver. All this is controlled by REL legendary filter sets and proprietary crossovers with 2 separate parametric equalizers permitting remarkably flat in-room response, while maintaining the speed and resolution for which modern RELs have become known.

    REL want our customers to enjoy all this performance without being limited to only a few room locations, so we built-in our legendary LongBow™ wireless receivers into every No. 25. This design utilizes zero compression, resulting in stunning dynamics and bass extension without being tethered to a cable, while delivering sound quality comparable to our competitor’s hardwired designs. It’s just another example of how we strive to offer complete and thoughtful solutions.

    Floor To Ceiling Bass

    When we experience bass in real time out in the world, it occurs with height to it. It strikes our sinuses, it kicks at our chest cavities, it rumbles along the floor conveying power authority and majesty. Our Reference Line Arrays permits bass to emerge more naturally, adding a height component in how it propagates throughout the room. Since 90 percent of the energy produced by a system resides in the bass regions, Reference Line Arrays are the magic element missing from so many otherwise state of the art systems. This air, transparency and, of course, effortless power that Reference Line Arrays convey can’t be imagined, it can only be experienced in person.

    Reliable Power

    It takes huge power to invest the No. 25 with the shattering dynamics of which it is capable. The rugged beast of a 1,000 watt NextGen3 amplifier that powers No. 25 has already proven itself in the field in one of our previous designs, making us comfortable with not only its startling sonic performance but also its reliability. However, No. 25 is no mere exercise in excess, but rather a thorough exposition in the art of rendering sub bass, totally, completely and with great deftness in tonality, expression and dynamics. Ultimately, this is what makes the No. 25 the addiction it quickly becomes.
