Master & Dynamic has partnered with Sir David Adjaye to design a bold and immersive new speaker that draws upon distinctive premium materials and sensory-focused craftsmanship for which both partners are known. Our MA770, a CES Innovation awards honoree, redefines the sound experience. Designed with Sir David Adjaye, the WiFi or Bluetooth connected speaker is made of an acoustically superior proprietary concrete composite. Audio componentry incorporates efficient dual 4″ woven long throw woofers and a 1.5″ titanium tweeter which are tuned to provide a rich, detailed and expansive sound that perfectly fills the home, office or studio. A magnetically attached stainless steel grille is removable for those that prefer the look of the exposed components and hand-finished concrete.
