Mark Audio, Alpair 12P

The Alpair 12P is a large full range single, paper cone drive unit (8″ – 206mm frame). The primary feature is its extended and detailed range, operating to 20kHz. The driver achieves this performance without using a whizzer or co-axial center tweeter making this driver a “puristʼs” single cone/cap design.

This driver incorporates a new cone multi-forming technology originally developed in Japan. The cones and made using 7 separate forming and trimming processes, all controlled via CNC operation. The accuracy of this technology is superior to conventional spun and press methods.

Tadashi Matsubara San, a most experienced senior driver designer from Japan has produced the rear suspension. It is unique and exclusively made for the Alpair 12. Lui Yi Ping from Taiwan is a specialist in front suspension design. He has produced the 7ʼs suspension as the most advanced of its type so far. Itʼs ultra-thin, and the production process for this component is all new. The same exclusivity is also applied to the frame, coil, connectors, every part for this driver is unique custom designed.

The acoustic result is remarkable for a large full range emitter, delivering outstanding clarity, detail and musical realism.
