 The Alpair 12 is a large full range single 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 centre tweeter making this driver a "purists"
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 7s
suspension as the most advanced of its type so far. Its 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.

 The CHP-70 is an all new paper cone full-range audio driver
from Markaudio. This driver is the first in a new technology line that
has a unique low-mass design and cone. The "engineered" approach was
applied by its designer, Mark Fenlon who passionately believes in
making all critical components to a very tight specification.
The CHP-70 boldly integrates all major components to offer a visually
colour co-ordinated driver. System builders now have an excellent
opportunity to make interesting designs that break away from the older,
more typical design box styling.
A very robust bass for this size of driver. Middle and high-range
delivery is accurate and detailed. New technology, excellent
performance and modern styling combined at an affordable price. The
outcome is "pure music".
