The ADAM S5A MK2 monitor transport the fundamental virtues of the A.R.T. technology and the HexaCone® woofers to much higher SPL regions. As the diaphragm areas involved are considerably enlarged an outstandingly impressive combination of natural sound and high dynamics is achieved.
The ADAM S5A MK2 is ; Two 11" HexaCone® woofers, a 5" HexaCone® midrange unit, an A.R.T. midrange and tweeter are capable of filling large control rooms with breathtaking realism and stunning dynamic peaks. A front panel carries variable controls for input sensitivity, level controls for tweeter and midrange amplifiers as well as ±6dB shelving filters on both ends of the frequency spectrum.

** 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.
