Martin Audio SXCF115-W – 15" Cardioid Flown Subwoofer (White)

Product Overview

The Martin Audio SXCF115-W is the white finish variant of the SXCF115, a compact cardioid flown subwoofer designed for rigged deployment with WPM flown line arrays, TORUS 8 constant curvature arrays, and Martin Audio point source systems requiring directional low-frequency pattern control. The white finish enables colour-matched permanent installation in light-toned architectural environments. The dual-driver cardioid architecture delivers rear rejection from 21dB at 43Hz to 28dB at 75Hz and 137dB peak SPL through independently amplified and DSP-processed 15" forward and 12" rear driver systems.

Product Description

The SXCF115-W delivers the same cardioid flown subwoofer performance as the SXCF115 in a white finish for permanent install environments where black hardware is architecturally incompatible with the interior design. The forward-facing 15" (380mm)/4" (100mm) voice coil driver with ferrite magnet and waterproof cone and the rear-facing 12" (300mm)/4" (100mm) voice coil driver with neodymium magnet and waterproof cone each operate in independently chambered bass reflex enclosures. The recommended iK42 amplifier optimises DSP parameters across both drivers to maximise rear rejection from 21dB at 43Hz to 28dB at 75Hz. Front-hemisphere outputs combine additively to deliver 137dB peak SPL — 2dB more than a conventional single 15" subwoofer — while rear-hemisphere cancellation keeps LF energy away from stages and reflective rear surfaces. The white birch ply enclosure with textured white paint, foam-backed perforated steel grilles on both driver positions, interlocking skids, and M20 top-surface thread plate supports singly stacked, pole-mounted, and rigged flown deployment. An input cover accessory provides weather resistance for outdoor use. The SXCF115-W is the appropriate selection for theatres, houses of worship, concert halls, and permanent live event venues with light-coloured architectural interiors where both cardioid LF pattern control and white finish hardware are specified.

Key Features

• White Finish — Colour-matched integration for light-coloured permanent install architectural environments.
• Cardioid Flown Subwoofer — Rigged deployment with WPM line arrays, TORUS 8, and point source systems.
• 21–28dB Rear Rejection (43–75Hz) — Minimises rear-stage LF radiation and reverberant LF buildup.
• 137dB Peak SPL — 2dB additional output versus a conventional single 15" subwoofer.
• Forward 15" Ferrite Driver — 380mm/4" voice coil, long excursion, waterproof cone.
• Rear 12" Neodymium Driver — 300mm/4" voice coil, long excursion, waterproof cone for cardioid rear cancellation.
• Separate Chambered Bass Reflex Enclosures — Each driver in its own independently optimised reflex chamber.
• Weather Resistance Option — Input cover accessory enables outdoor deployment.

Typical Applications

• Flown cardioid LF complement for WPM line arrays in theatres and concert halls with white interior finishes
• House of worship flown LF with rear-stage rejection and white finish requirements
• TORUS 8 constant curvature array LF reinforcement in white-finish environments
• Live event venues requiring controlled LF pattern and white hardware
• Government and civic facilities with architectural white finish specifications
• Broadcast studios and corporate AV permanent installs with white finish requirements

Frequently Asked Questions

What is the difference between the SXCF115 and SXCF115-W?

The SXCF115-W is acoustically identical to the SXCF115. The only difference is the white finish for colour-matched permanent installation in light-coloured architectural environments.

What amplifier is recommended for the SXCF115-W?

Martin Audio recommends the iK42 four-channel amplifier, which is pre-configured with DSP optimised for maximum cardioid rear rejection across the SXCF115's operating range.

Does the SXCF115-W require specialised amplification?

Yes. The forward and rear drivers each require an independent amplifier channel with DSP processing. The iK42 is the recommended solution.

Can the SXCF115-W be used outdoors?

Yes. An input cover accessory makes the SXCF115-W weather resistant. Both driver cones are waterproof, supporting outdoor deployment.

What deployment configurations does the SXCF115-W support?

The SXCF115-W supports singly stacked (interlocking skids), pole-mounted (M20 thread plate), castor-wheeled (optional), and rigged flown configurations via accessory rigging hardware.

What is the difference between the SXCF115-W and the SXCF118-W?

The SXCF115-W uses a 15"/12" driver pair suited to WPM and TORUS 8 arrays; the SXCF118-W uses an 18"/14" driver pair providing higher output for WPS line array applications.
