The MartinLogan ML-75R is part of the Installer Series, designed to provide high-quality outdoor audio solutions with excellent performance and durability. Its rock-inspired design blends seamlessly into gardens, patios, and landscaped outdoor spaces, making it an ideal choice for residential outdoor entertainment systems.

At its core is a 7.5-inch mineral-filled polypropylene woofer with a dual voice coil, paired with two 1-inch titanium dome tweeters. This configuration delivers stereo sound from a single enclosure, providing balanced audio reproduction with clear high frequencies and impressive low-frequency response.

Built to withstand challenging outdoor conditions, the ML-75R features a fully sealed, reinforced enclosure with mineral filling and a realistic faux-stone finish. Its stainless steel grille is resistant to water and UV exposure, providing additional protection against weather elements while maintaining its appearance over time.

With a frequency response of 63 Hz to 20 kHz, 90 dB sensitivity, and recommended amplifier power of 20–80 watts per channel, the ML-75R offers versatile performance for outdoor listening areas. Its dual voice coil design supports stereo playback from a single speaker, making it particularly useful in spaces where installing multiple speakers may not be practical.

The ML-75R is an excellent solution for landscape audio installations where high-quality sound, weather resistance, and discreet aesthetics are equally important.
