Concrete that absorbs echoes
MA770 SPEAKER MASTER & DYNAMIC
Concrete speakers are great for combating rattle-inducing vibrations, but the trade-off is typically unwanted echo. This 35-pound Brutalist monolith has a tapered shape and is made from a proprietary blend of concrete with polymers in the mix to dampen the reverberations. Sound comes courtesy of a pair of 4-inch woven Kevlar long throw woofers and a 1.5-inch titanium tweeter embedded in the cabinet.
