CONCENTRIC DRIVERS

CONCENTRIC DRIVERS

The Monolith™ OW3 uses three 4.5" concentric drivers, each with an inset 20mm tweeter. The polypropylene cones have thick NBR surrounds, while the silk dome tweeters are equipped with waveguides and neodymium magnets. The drivers have been tuned for maximum performance in a slim, small enclosure. The speaker has been outfitted with six passive radiators to add depth and punch to the bass. For best performance, we recommend the Monolith™ On‑Wall Speaker be paired with a Monolith subwoofer.
