Features & Specs Line Circle

18″ carbon fiber driver with 4″ voice coil and dual-spider suspension
The SPL-X 18’s flagship driver offers immense cone area and excursion potential, with a rigid carbon fiber cone, dual-spider suspension and triple ferrite magnet system. This combination enables extremely deep bass levels while maintaining accuracy.
1800 W RMS / 2500 W peak Class D amplifier
The high-output Class D amplifier delivers 1800 W continuous power and up to 2500 W peak, supporting very high SPLs without loss of control. This power capability is vital for reproducing modern film soundtracks with full-scale LFE effects.
DSP with AutoEQ, parametric EQ and app control
AutoEQ with microphone analyzes the room and applies correction, while a 6-band parametric EQ offers detailed manual shaping. Control via app lets users set crossover, phase, filters and presets from the main listening position.
Sealed, reinforced HDF cabinet for ultra-deep, controlled bass
The large sealed HDF enclosure is heavily reinforced to control resonances and maintain structural integrity under high acoustic stress. This supports the production of very deep bass frequencies with clarity and control.
Extensive RCA, XLR and high-level inputs/outputs
Stereo and LFE inputs/outputs on both RCA and XLR plus high-level inputs allow the SPL-X 18 to integrate into advanced systems, including multi-sub and balanced installations. This flexibility makes it suitable for both high-end home and professional-style environments.
Auto power-on and multi-voltage operation
On/Auto/Trigger power modes and adjustable auto power-on sensitivity streamline day-to-day use. Universal 115–230 V operation makes it easy to deploy the SPL-X 18 in different markets.
