Martin Audio SXC118-W – 18" Cardioid Portable Subwoofer (White)

Product Overview

The Martin Audio SXC118-W is the white finish variant of the SXC118, a compact, high-performance cardioid portable subwoofer engineered for touring sound reinforcement and permanent installations where directional LF pattern control is required. The white finish enables colour-matched integration in light-toned permanent install environments while delivering identical cardioid subwoofer performance to the black SXC118. The dual-driver cardioid architecture achieves 28dB of rear rejection at 75Hz for controlled directional LF reinforcement.

Product Description

The SXC118-W implements the same cardioid subwoofer architecture as the SXC118: a forward-facing 18" (460mm)/4" (100mm) voice coil driver and a rear-facing 14" (356mm)/3.5" (88mm) voice coil driver, each driven by independent amplifier channels and DSP. This produces a cardioid dispersion pattern that maximises LF output toward the audience while reducing rear-hemisphere LF radiation by 28dB at 75Hz. The white finish is specified for permanent install environments where black hardware is architecturally incompatible — houses of worship with light interiors, theatres, and hospitality venues. Integrated flying inserts in the tour-grade plywood enclosure support ground-stack and elevated deployment options. The SXC118-W provides system designers with the full cardioid subwoofer performance benefits — reduced rear-stage LF spill, minimised reverberant LF energy, improved system transient accuracy — in a white finish appropriate for the broadest range of permanent install environments.

Key Features

• White Finish — Colour-matched integration for light-coloured permanent install architectural environments.
• Cardioid Portable Subwoofer — Ground-stack variant with flying inserts for optional elevated deployment.
• 28dB Rear Rejection at 75Hz — Reduces rear-stage LF spill and reverberant energy buildup.
• Forward 18" Driver — 460mm/4" voice coil driver maximises front-hemisphere LF output.
• Rear 14" Driver — 356mm/3.5" voice coil driver creates cardioid cancellation in the rear hemisphere.
• Independent Amplifier Channels & DSP — Each driver requires independent amplification and DSP for correct pattern formation.
• Tour-Grade Plywood Enclosure with Flying Inserts — Durable construction supports both portable and elevated deployment.

Typical Applications

• House of worship permanent cardioid LF installs with light-coloured architectural interiors
• Theatres requiring directional LF control with white-finish hardware
• Live event venues and nightclubs with white finish hardware specifications
• Corporate AV environments with architectural aesthetic requirements
• Acoustically challenging rooms requiring cardioid LF pattern control
• Hospitality venues with white or light-coloured interior finishes

Technical Specifications

Frequently Asked Questions

What is the difference between the SXC118 and SXC118-W?

The SXC118-W is acoustically identical to the SXC118. The only difference is the white finish for colour-matched permanent installation in light-coloured architectural environments.

Does the SXC118-W require specialised amplification?

Yes. The forward and rear drivers require independent amplifier channels with DSP processing for correct cardioid pattern formation.

Can the SXC118-W be flown?

Flying inserts are included, supporting elevated deployment. For rigged integration within WPS line array configurations, the SXCF118-W dedicated flown variant is the recommended selection.

Is the SXC118-W suitable for permanent installation?

Yes. The SXC118-W is appropriate for permanent installs in environments where white finish is architecturally specified and cardioid LF pattern control provides system benefits.
