The Martin Audio SX118 is a compact, high‑performance 18-inch subwoofer built to deliver authoritative low end in space‑conscious systems. Capable of up to 138dB SPL and extending response down to 47Hz, it provides tight, punchy bass that adds weight and headroom to full‑range loudspeakers without sacrificing clarity. With an 8 Ohm impedance, the SX118 integrates easily with a wide range of professional amplifiers and can be deployed as a single unit, coupled in pairs, or configured as part of larger bass arrays.
Engineered for reliability and consistent results, the enclosure is robust and well‑suited to mobile events, touring applications and fixed installations. Its compact footprint makes it ideal where floor space is limited, while its controlled low‑frequency performance enhances music playback and reinforces speech with confidence.
From live music venues and clubs to corporate AV, houses of worship and multi‑purpose performance spaces, the SX118 provides impactful, controlled sub‑bass in a practical, professional package. A smart choice wherever you need extended low‑frequency performance from a compact enclosure.
