All Velodyne Acoustics SPL-X Series Subwoofers Products

The Velodyne Acoustics SPL-X Series Subwoofers bring reference-level bass performance to serious music and home theater systems, combining advanced DSP, powerful Class D amplification and ultra-rigid carbon fiber drivers in a compact sealed design. Engineered as the subwoofer flagship line from Velodyne, the SPL-X 10, SPL-X 12, SPL-X 15 and SPL-X 18 deliver fast, controlled low frequencies with the authority to energize any room, from dedicated cinemas to high-end stereo setups.

Each SPL-X subwoofer is built around a high-performance driver with dual-spider suspension, a triple-vented basket and oversized 3- or 4-inch voice coils, powered by Class D amplifiers rated up to 1800 watts RMS for the largest models. This muscle is managed by a cutting-edge DSP platform with fully parametric 6-band EQ and AutoEQ room calibration using the included microphone, helping you achieve smooth, distortion-free bass tailored precisely to your listening space.

For installers and enthusiasts, integration is straightforward and flexible: every SPL-X model offers RCA LFE, RCA stereo, XLR LFE, XLR stereo and high-level speaker inputs, making it easy to add flagship low-frequency performance to both hi-fi systems and immersive surround sound theaters. From compact rooms that benefit from the agility of the SPL-X 10 and SPL-X 12, to large, dedicated theaters that demand the sheer output of the SPL-X 15 and SPL-X 18, you can build a perfectly matched low-end foundation across your entire system.
