2-way, active near/midfield monitor featuring ADAM's folded ribbon tweeter technology and superior sound.
The ADAM P22A monitor is a two-way shielded powered studio monitor designed for applications where deeper bass and louder volumes are needed. Featuring superb imaging as a result of ADAM's proprietary A.R.T. (Accelerated Ribbon Technology) folded ribbon tweeter, the P22A active monitor is ideally suited for project studios as well as professional recording and broadcast facilities.
Two built-in amplifiers are individually housed in the P22A monitor and exhibit excellent dynamic behavior due to their low output impedance. They represent a new audio performance oriented approach to amplification and combine excellent sound quality with cool operation. On the back panel additional controls for level and room EQ are offered. The P22A monitor 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.
