The MILAN M18 is a self-powered bandpass subwoofer enclosure consisting of an 18" low frequency driver housed in an optimally tuned enclosure, together with an integrated lightweight 1kW Class D amplifier.
The amplifier provides two input channels with balanced jack/XLR connectors, and two link outputs on male XLRs, providing connections to further Milan mid-high cabinets or subwoofers. A filtered high-pass output also provides connections to other mid-high cabinets. The left and right signals are summed in the subwoofer through a low-pass filter to the 18" driver. A sub level control is provided in order to achieve an even level between the subwoofer and Milan mid-high cabinets. The M18 is available in two versions to suit regional AC mains voltages of either 110 volts or 230 volts, and mains power is supplied via an IEC mains connector.
The Class D amplifier features sophisticated signal processing which provides limiting functions to ensure high performance and long term reliability. Status LEDs indicate mains power, signal present and signal limit. The cabinet is constructed from 15mm laminated plywood and is finished in dark blue textured paint. A pole mount socket is fitted to allow Milan M15 cabinets to be mounted on optional 35mm speaker poles.

One of the best ways to fill the room with bass with your PA system is by adding a subwoofer. Mackie's Thump 118S powered subwoofer was designed to boost the low-frequency power and output of a PA system using their Thump Series powered speakers, but it'll work with any system that needs more bass. This sub features a built-in amplifier that sends up to 1400 watts to the 18" low-frequency driver in an efficient bandpass enclosure, creating plenty of bass energy for just about any musical application or venue. Internal protection circuits keep the sub rockin' and safely under control, even when the party gets loud and raucous.
Integrates well
Selectable High Pass Modes with a variable crossover setting optimizes the sub for different system configurations and musical genres. A 2-channel input mixer plus 2 full-range and 2 high-pass outputs offer plenty of wiring and integration options. Convenient, top corner handles help ease the pain when carrying this Built-Like-A-Tank™ sub to and from a gig.
