A3X - Description | ADAM Audio GmbH With the A3X, ADAM Audio present their smallest monitor to date, making it perfectly suited for all environments where space is limited but sound shouldn’t be constricted. The A3X combines a tiny footprint with the much acclaimed ADAM sound quality by using the X-ART tweeter for the higher frequencies, a guarantee for crystal clear music reproduction. A 4.5” (basket) driver handles the lower registers. The diaphragm is made from carbon fiber, a material that is very light but very stiff and therefore capable of delivering colouring-free sound. Two built-in 25 Watt amplifiers powers each of the drivers directly.
