The MAD Array uses Planar Magnetic Transducers, which are the best sounding devices currently available for sound reproduction. Planar Magnetic technology has been around for almost 50 years. Until now, this technology was associated with the high-end home loudspeaker market. Although the sound quality was extraordinary, there was a big limitation for using this technology in the professional market. The transducer's price was too high and efficiency was not enough to justify the use. HPV Technologies is the first company in the world to be able to overcome these restrictions and introduce high-end sound to the professional market. There is no practical limitation on the final sound pressure level and desired sound coverage. The MAD Array can be adapted for any professional application. The MAD Planar Magnetic Surface Array™ is a one-way (full-range) loudspeaker system. The entire amplification system and digital signal processing system are simplified and is cheaper than in the conventional three or four-way Pro Systems.

The MAD Array is full-range and only requires high pass filters. There are no crossover and phase issues in the critical voice region. Many singers who have used the system said that this is the first time they can hear their "true" voice as it is supposed to sound.

The MAD Array has a huge radiating surface. This enables excellent air coupling to the transducer diaphragms and high efficiency. HPV Transducers use lightweight stretched diaphragms and very strong neodymium magnets. Diaphragms are whole surface driven with strong and uniform force. That is why the MAD Array plays at such loud volumes with so little distortion. Now, for the first time, people can listen to very loud volumes for a long period of time without the usual fatigue and ringing of the ears. For example, in Arco Arena in Sacramento, California it is possible to achieve 115-117 dB Sound Pressure Level with clear, undistorted sound even in the most distant seats with peaks of 127 dB. Transient response is extraordinary. Intelligibility of the sound is so good that an audience can hear and understand every single word even in rooms with poor acoustics. MAD Surface Array™ Technology can solve the most difficult acoustic problems where traditional systems usually fail.
