The in-fill speakers for the Mach installation series have been designed for commercial
venues such as cafés, clubs, department stores, conference rooms, and hotels, that require
high-fidelity in-fill sound.
The goal of the in-fill speaker design is to provide true hi-fi performance with high speech
intelligibility in a compact package. As background noise in these venues is typically
located in the mid-frequency area, the in-fill speakers are acoustically optimized for clarity
and openness in the mid-range.
The M42i and M62i are top-boxes that can be supported by the M208i sub-woofer or the
bass output of the venue’s main PA system.
The M208i is a stereo subwoofer with an integrated high-pass filter that enables the sub
and two top-boxes to be powered by one amplifier. It has been made as compact as
possible using the bandpass principle, which maximizes the output-to-size ratio.
The M68i is a full-range speaker with usable bass-output down to 60 Hz; it can be used as
a stand-alone box without subwoofer support.
All Mach in-fill top-boxes have wide, even dispersion that ensures good coverage in low-
ceiling applications.
