Q 118SA

This high-performance subwoofer features a robust 18″ woofer with a 4″ voice coil, driven by a powerful 1200W RMS Class D amplifier and an efficient switch-mode power supply for consistent output. The integrated DSP offers maximum versatility through 6 tailored presets and a 6-step digital Delay for precise system alignment.

The comprehensive control panel includes three status LED indicators, controls for Phase, Level, and Preset/Delay, along with stereo XLR input and link connections. Power management is streamlined via powerCON TRUE1 duplex connectivity, allowing for easy daisy-chaining.

Built for the rigors of the road, the 0.70″ Baltic birch plywood cabinet is finished in a scratch and scuff-resistant paint. For flexible installation and transport, the unit is equipped with two M20 top-mount speaker sockets, four ergonomic aluminum handles, and provides the option for rear-mounted wheels.

PRESET

• ORIGINAL: general preset, suitable for the majority of uses. Low pass filter is set at 95Hz, peak limiter is adjusted for getting the perfect balance between high SPL and low distortion

• DEEP: this preset extends and boosts subwoofer low range to approx. 40Hz. Low pass filter is set at 95Hz, peak limiter is extremely fast and guarantees to remove almost completely the distortion due to amplifier clipping. This necessarily causes little reduction in maximum SPL. Generally recommended for applications requiring extremely pure sound and maximum low frequency extension.

• PUNCH: Preset providing maximum power concentration in the 60 – 95Hz frequency range. Perfect for rock music and high power applications. Distortion is slightly higher, since it is less limited by the peak limiter, while sound pressure level increases. Low pass filter is set at 95Hz.

• INFRA: Similar to DEEP as for the extension and absence of distortion. It differs for low pass filter setting at 75Hz. This allows for ground-stacked use of the subwoofer in applications featuring also a flying subwoofer. Thanks to the all pass filter for phase alignment, the frequency overlap in the 50Hz – 75Hz range for the two subwoofers is perfectly in phase.

• CARDIOID REAR ORIGINAL 1 FRONT: preset to be used in systems with two subwoofers; select the ORIGINAL preset on the speaker oriented toward the audience.

• CARDIOID REAR ORIGINAL 2 FRONT: preset to be used in systems with three subwoofers; select the ORIGINAL preset on the two speakers oriented toward the audience.
