REL Acoustics HT/1510 BLACK Serie HT 15-Inch Powered Subwoofer in Black (Each)
The REL Acoustics HT/1510 BLACK Predator powered home theater subwoofer from the SERIE HT lineup combines a 15 in CarbonGlas driver, built-in 1,000-watt RMS Class D amplification and a sealed, front-firing enclosure, with in-room low-frequency extension of -6 dB at 20 Hz. Stereo RCA, LFE RCA and LFE XLR inputs offer wired connection options, while an optional HT-Air MKII wireless adapter is sold separately. Designed for movies, games and concert films as well as music, this flagship brings dedicated low-frequency support to a theater or shared living space.
Key Features
Black Line-Grained Finish and BrilliantBrace
Five coats of hand-rubbed high-gloss lacquer finish the top plate, contrasting with the horizontally oriented line-grained black composite cabinet. Inside, BrilliantBrace supports the rear of the driver and reinforces the cabinet walls to limit unwanted mechanical energy. The construction brings together visible-room styling and structural support for the large driver.
15 in CarbonGlas Driver
Glass fiber keeps cone mass low, while an inverted carbon fiber center cap adds stiffness to the long-throw assembly. A 3 in voice coil and steel chassis complete a driver designed to retain responsiveness for music and theater use. The emphasis is on low-frequency impact without uncontrolled overhang, leaving the main speakers to handle the rest of the soundtrack.
1,000 Watts RMS with PerfectFilter
A linear power supply and four-MOSFET Class D output stage are designed to keep current in reserve for sudden explosions and demanding effects. PerfectFilter emphasizes immediate bass delivery, while dual parametric filtering is also provided. With the power amplifier inside the cabinet, there is no separate subwoofer amplifier to add.
RCA, XLR and Daisy-Chain Connections
Use stereo low-level RCA for left/right pre-outs, or choose LFE RCA or LFE XLR for a matching subwoofer output. Corresponding RCA and XLR daisy-chain outputs provide connection points for additional subwoofers as a system expands. A signal interconnect is not included.
Expandable Three-High Stacking
Full-depth support rails and included milled-aluminum couplers let you build a vertical stack up to three subwoofers high. Add units incrementally to extend the scale of bass reproduction through the height of a large-screen installation. This configuration includes one subwoofer; all additional units are purchased separately.
Optional Wireless Signal Connection
Where running a wired audio connection is inconvenient, HT-Air MKII offers an optional signal path from subwoofer outputs or left/right RCA pre-outs. Airship II is also compatible. Both wireless accessories are sold separately, and neither is included. Wireless audio does not eliminate the need for AC power; a 6 ft AC power cord is supplied.
Room Guidance and Mixed-Series Integration
For room planning, REL Acoustics identifies spaces over 200 square feet as ideal for this design, allowing space to operate without excessive bass energy. For installations that already include Serie T/x or Serie S products, complementary visual and sonic design supports a coordinated mixed-series system.
