Ribbon Power from ADAM
The three-way S4V MK2 features a 12" woofer, a 5" HexaCone Midrange and the A.R.T tweeter. The large size of the bass driver combined with 500 W of sheer amplifier power dedicated to this driver alone enable this monitor to deliver low bass information loud and clear. The S4V's capability to create realistic 3-D soundscapes makes them the ideal choice for the discerning surround sound engineer.
The A.R.T. (Accelerated Ribbon Technology) tweeters and midrange units take a 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 "motor" is responsible for the enormous clarity and transient reproduction that is to be heard from the A.R.T. drive units.
