The MM Acoustics M4.18 Quadstack Bundle comprises four horn‑loaded 18-inch subwoofers designed to deliver authoritative, high‑impact low end for touring and installation. Working as a quad, the system reaches up to 153 dB maximum SPL with a tight, punchy character and excellent projection. Each compact 62 kg cabinet offers a 35–200 Hz (‑3 dB) response and 112 dB sensitivity (1 W/1 m), extracting impressive output from modest amplifier power. Rated at 1800 W AES, 3600 W programme and 10,000 W peak at 8 Ω, the M4.18 provides the headroom modern electronic, live and playback content demands.
Cabinets are built from robust multiplex beech with a hard‑wearing black Warnex finish (RAL9005) and optional RAL colours. A metal grille with backing foam adds driver protection, while dust and splash resistance support temporary outdoor use. Connectivity is via dual Neutrik Speakon NL4, and optional stackware enables seamless pairing with M28LA systems. Each enclosure measures 700 x 580 x 900 mm, simplifying truck‑pack and ground‑stack configurations.
Ideal for clubs, festivals, mobile production and permanent installs that need compact form, strong low‑frequency punch and high output.
