Winner of the 2007 Musikmesse International Press Award (m.i.p.a.) for best studio monitor!
The A7 Powered Studio Monitor from ADAM Audio matches the A.R.T. (Accelerated Ribbon Technology) tweeter with a state of the art 6.5 woofer. The woofer introduces a new cone material that combines high rigidity and high internal damping with low weight. The result is an extremely accurate studio monitor with all the clarity, detail and spectacular imaging traditionally associated with the ADAM name.
The A7 monitor 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 A7 powered studio monitor also features both balanced (XLR) and unbalanced (RCA) input connectors, allowing it to be used in almost any audio application.
The A7 monitor enclosure is magnetically shielded.
Accelerated Ribbon Technology
The A.R.T. (Accelerated 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 A.R.T. 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 A.R.T. drive units.
A.R.T. tweeters are superior in musical clarity and transient reproduction. They have an above average efficiency of ~93 dB/W/m, a perfectly linear impedance of 3.2 ñ 0.05 Ohms, an equally perfect phase response of ñ 1ø within the used bandwidth, a reasonable directivity characteristic and a thermal power handlin g that exceeds that of 1" domes by a factor of 2 to 3. Summed up here is a completely new transducer that has no weaknesses in terms of operation, compatibility, reliability or other electroacoustic specifications. Looking back into loudspeaker history you will not find anything comparable.
