Velodyne Acoustics SPL-X
The subwoofer flagship from Velodyne Acoustics
The SPL-X subwoofer always provides the decisive low-frequency foundation in the system – and is immediately ready for use thanks to numerous presets. Thanks to XLR and RCA as well as high-level inputs, the SPL-X can be seamlessly integrated into any audio environment. Whether in the studio, home theater or living room: you can rely on the bass of the SPL-X series.
With the SPL-X series, Velodyne Acoustics redefines the subwoofer flagship and continues on the path of SPL Ultra and the legendary DD series
The high-end subwoofer series combines pioneering DSP technology, a powerful Class D power amplifier and carbon drivers with a fully parametric 6-band EQ. The automatic room calibration ensures linear, rich bass in every room and avoids distortion.
The SPL-X subwoofers deliver pure performance right down into the frequency range – with up to 1800 watts RMS and massive 4-inch voice coils on the larger models. The flagship drivers with dual-spider suspension and vented baskets guarantee maximum control, even at extreme levels. The volume, crossover frequency, phase and EQ can be conveniently controlled from the listening position via the free app.
