The Predator, Significantly Upgraded

REL's HT/1508 Predator won Home Theater of the Year awards on multiple continents. The HT/1510 Predator II upgrades it in just about every area: a 1,000-watt RMS amplifier with a monster linear power supply, a new 15-inch CarbonGlas driver that handles 40% more power, and specialized HT versions of REL's award-winning PerfectFilter that deliver flat deep bass down to 20Hz. The result is the highest .1/LFE output of any REL ever built.

A 15-Inch Driver Built for Slam

The CarbonGlas driver pairs a lightweight glass fiber cone with a true carbon fiber center cap, letting the 3-inch voice coil accelerate the cone instantly while the structure stays composed under the most massive signals. Quick, reactive bass with the slam that defines great theater sound—and the speed to serve music beautifully too. Inside, REL's BrilliantBrace quiets and redirects energy trapped in the driver, damping the top, bottom, and side walls of the sleek line-grained cabinet.

Stack It to the Sky

Uniquely REL: Predators are designed to stack up to three units high using included milled-aluminum REL Couplers that bolt lower units to upper. A full stereo stack—six subs, three per side—musters over 8,000 watts of peak power and six 15-inch drivers for truly oceanic bass behind massive projection screens. Available in Black or White to match the rest of your REL family, and blendable with Serie T/x and Serie S in multi-REL systems.

Frequently Asked Questions

How is the Predator II better than the original HT/1508?

More of everything owners loved: power jumps from 800 to 1,000 watts, the new 15" driver handles 40% more power, the HT PerfectFilters extend flat response to 20Hz, and the restyled cabinet matches REL's Reference-series proportions. It also delivers the highest .1/LFE output of any REL to date.

Can I use REL's High-Level connection with it?

Yes—wirelessly. While the HT series omits the wired Speakon input, adding REL's optional AirShip II gives the Predator II a wireless High-Level input fed from your main amplifier's outputs, for the rich, full-range REL blend in a two-channel or theater system.

Which rooms does it suit?

Large rooms and dedicated theaters—this is the flagship of REL's HT line. For smaller spaces, consider the HT/1205 MKII or HT/1003 MKII. And for the ultimate setup, stack Predators up to three high per side.

Is it good for music as well as movies?

Yes. The lightweight CarbonGlas cone and analog PerfectFilters keep the bass fast and articulate, so it serves large-scale music with the same speed and composure it brings to film effects.
