Velodyne is the undisputed authority in low-frequency reproduction. Every design, from driver to DSP, is engineered for precision, power, and musicality. With models spanning compact sealed cubes to reference-grade cinema beasts, Velodyne delivers bass that transforms music, movies, and games into visceral, full-body experiences.

Dedicated to the lowest octaves, subwoofers extend your system’s reach into deep, tactile bass you can both hear and feel. They relieve main speakers of demanding low-frequency duties, adding scale, impact, and immersion—whether it’s the rumble of film soundtracks or the foundation of live music.

X-TRAORDINARY BASS EXPERIENCE

SPL-X Series channels over 40 years of Velodyne subwoofer innovation into four sealed-box designs—each precision-engineered for musicality, control, and brute-force bass when it counts. Whether you’re chasing low-end finesse or blockbuster slam, SPL-X delivers seismic performance with pinpoint accuracy, turning every listen into a full-body experience.

SPL-X 18

The flagship 18” subwoofer in the series, SPL-X 18 houses a four-layer 102mm voice coil, 15kg motor, and delivers up to 1,800W RMS (2,500W peak). At 550 x 560 x 620mm, it’s built for large rooms and listeners who demand real infra-bass—clean, seismic, and in full control down to 13Hz.

THE COMMAND OF CARBON FIBRE

SPL-X’s carbon fibre cone is ultralight and exceptionally rigid, enabling fast, piston-like movement with minimal distortion. It preserves the fine contours of bass instruments and cinematic effects alike—delivering clarity, texture, and transient precision that lesser materials simply can’t match.

GARDIANS OF FIDELITY

SPL-X’s Class D MOSFET amplifier delivers up to 1,800 watts RMS and 2,500 watts peak—without sacrificing precision. Designed in lockstep with the driver, it supplies clean, efficient power that protects detail, preserves dynamics, and keeps distortion out of the musical equation.

BUILT LIKE A BASS VAULT

Each SPL-X model features a sealed high-density fibreboard (HDF) cabinet with internal bracing, 25–35 mm thick walls, and a reinforced front baffle. This design minimises resonance and eliminates port noise, ensuring clean impulse response and deep, tight bass—even at high volumes .

TOTAL CONTROL BELOW 200HZ

Beyond Auto EQ, SPL-X offers deep DSP customisation with six-band parametric EQ, subsonic filtering, and fully adjustable crossovers. Tailor bass to your room, your system, or your mood—then save it. From tight jazz sessions to blockbuster LFE, it’s your sound, and you’re in control.

DRAMA BEGINS WITH THE DRIVER

Triple-stacked ferrite magnets, a four-layer voice coil, and a 15 kg magnet assembly give SPL-X a formidable motor system with extension down to 13 Hz and ±3 dB response reaching up to 250 Hz (model dependent), delivering visceral slam and fine-layered detail that turns dynamics into drama, and silence into suspense.

TAILORED TO YOUR SPACE

SPL-X includes a calibrated measurement microphone and uses the Velodyne Acoustics AutoEQ SUB app for precision room calibration. So you can initiate sweeps from both the back panel or app to analyse in-room frequency response and apply DSP corrections for clean, coherent bass performance.

EVERY CONNECTION COVERED

Whether you’re running a modern AV processor, vintage stereo amp, or something in between, SPL-X is ready. With RCA, XLR, speaker-level inputs, and trigger in/out, it fits into any system—and even supports daisy-chaining for multi-subwoofer control.
