HH Audio TRS-1800 18-Inch Passive Subwoofer

HH Audio Tensor TRS-1800 18-Inch 1400W Powered PA Subwoofer

Add powerful, extended low-frequency performance to your live sound system with the HH Audio Tensor TRS-1800 Powered Subwoofer. Designed for bands, DJs, venues, houses of worship, mobile entertainers, and professional PA applications, the TRS-1800 combines a high-grade Class D amplifier with a long-throw, HH-designed 18-inch bass driver.

Delivering up to 1,400 watts peak power and a maximum peak output of 130 dB SPL, this active subwoofer provides the punch, depth, and low-end reinforcement needed for music playback and live performance. Its frequency response extends down to 35 Hz, helping kick drums, bass guitars, electronic music, and cinematic effects sound full and authoritative.

Powerful 18-Inch Low-Frequency Driver

The TRS-1800 is equipped with an HH-designed professional 18-inch woofer engineered for strong bass response and dependable performance. The bass-reflex enclosure uses optimized porting to enhance efficiency and deliver deep, controlled low frequencies without requiring a separate power amplifier.

Flexible Stereo Signal Routing

Dual balanced left and right XLR inputs make it easy to integrate the TRS-1800 into mono or stereo PA systems. Balanced XLR link outputs allow the full-range signal to be passed to additional equipment, while dedicated high-pass XLR outputs provide cleaner crossover separation between the subwoofer and your powered main speakers.

Adjustable Crossover and Sound Modes

A variable crossover control lets you adjust the operating range from 60 Hz to 200 Hz to suit your speakers, room, and application. Select the Flat mode for a balanced low-frequency response or engage the Shape preset to boost subharmonic frequencies for deeper, more pronounced bass.

Built for Live Sound

The durable cabinet is constructed from 15mm MDF with an 18mm MDF baffle and finished in rugged black spatter paint. A heavy-gauge powder-coated steel grille with acoustic foam backing protects the driver, while the integrated 35mm pole socket allows a compatible full-range speaker to be mounted above the subwoofer.
