ADAM P33-A pair #75870/75871 (Used)

The ADAM P33-A is an excellent choice for recording enthusiasts who want the advantages of ADAM's unique mirrored S3-A design at a lower price point. Like the S3-A, one woofer acts as a full-range driver with the second woofer joining it only below 150Hz. This unusual approach effectively doubles the area and power of the woofer when it needs to respond to deeper frequencies, resulting in an exceptional low end without compromising midrange performance.

The P33-A is shielded and has three 100 W amplifiers that deliver outstanding dynamic performance. It can be used either horizontally or vertically, so that very flexible positioning within the studio is possible.

The ADAM P-Series of active Monitors is made for post production, home studios, and mobile recording. They offer the original A.R.T. (Accelerated Ribbon Technology) tweeter with its unsurpassed clarity in a lower price region and deliver a stunning precision in sound reproduction.

The ADAM Audio A.R.T. Folded Ribbon Technology:
ADAM Audio's 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 thin 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.
