We created a new geometry for this speaker. A new geometry of sound, says architect Sir David Adjaye of this 'MA770' design. Made in collaboration with Master & Dynamic, it's built from a proprietary concrete composite that's great for acoustics - so much so, that you can play music at full blast without causing the table to vibrate. The dual Kevlar long-throw woofers and titanium tweeter provide crystal clear sound, while the magnetically attached stainless steel grille can be easily removed for a more industrial look. Connect via WiFi, Bluetooth or aux cable.
