The A7 matches the A.R.T. tweeter with a state of the art 6.5-inch woofer that introduces a new cone material combining high rigidity and high internal damping with low weight, resulting in an extremely accurate monitor with all the clarity, detail and spectacular imaging traditionally associated with the ADAM name.
The A7 is powered by two 50W RMS amps (one per driver). The front panel sports both a power switch and volume control. The rear panel houses controls for tweeter level and two shelving filters for high and low frequencies. The unit also features both balanced (XLR) and unbalanced (RCA) input connectors, allowing it to be used in almost any audio application.
ART (Accelerating Ribbon Technology)
The ART (=Accelerating Ribbon Technology) tweeters and midrange units take a completely new approach in kinematics to move air and improve the quality of music reproduction. Based on the original works of Dr. Oskar Heil, who invented his "Air Motion Transformer" back in 1972, new electroacoustic transducers have been developed that are based on improved layouts and new materials.
The membrane consists of a lamella like folded diaphragm whose single folds move according to the alternate current, thus squeezing air in and out. All other loudspeaker drive units, whether they are voice coil driven, electrostatics, piezos or magnetostatics, act like a piston, moving air in a 1:1 ratio. This is undesirable, as the specific weight of air is much lower than that of the driving mechanics. Speaking in terms of electrical Engineering one could say there is a bad match between source and load.
The ART principle achieves a 4:1 velocity transformation between driving diaphragm and driven air, i. e. the air moves in and out four times faster than the folds itself are moving. This superior "motor" is responsible for the enormous clarity and transient reproduction that is to be heard from the ART drive units.
