Features & Specs
15″ carbon fiber driver with 4″ voice coil and triple ferrite magnet
The large 15″ driver is built for serious output, with a stiff carbon cone, dual-spider suspension and a robust 4″ voice coil on a triple ferrite magnet system. This combination provides the displacement and control necessary for impactful bass in large rooms.
1500 W RMS / 2000 W peak Class D amplifier
The SPL-X 15’s Class D amplifier delivers substantial continuous power and high peak capability, ensuring that even the most explosive soundtracks are reproduced without strain. High efficiency also helps manage heat and maintain consistent performance over long sessions.
DSP with AutoEQ, 6-band EQ and app control
Advanced DSP, including AutoEQ with microphone, automatically optimizes the subwoofer to the room, while a 6-band parametric EQ offers precise manual tuning. App-based control makes it easy to adjust crossover, phase, volume and filters without leaving the listening position.
Sealed, reinforced HDF cabinet for controlled high-output bass
The substantial sealed enclosure is constructed from reinforced HDF to control cabinet resonances and maintain tight, articulate bass even at high SPLs. This helps the SPL-X 15 deliver both impact and clarity.
Flexible RCA, XLR and high-level connectivity
With stereo and LFE inputs/outputs on both RCA and XLR plus high-level speaker inputs, the SPL-X 15 works seamlessly in complex installations and multi-sub configurations. Balanced XLR connections are particularly beneficial in longer cable runs and more noise-sensitive environments.
Auto power-on and multi-voltage operation
On/Auto/Trigger power modes and adjustable auto power-on sensitivity ensure the sub responds appropriately to incoming signals. Support for 115–230 V operation allows straightforward deployment in different regions.
