This Alpair 10P Gen.1 represents a significant development of Markaudio Full-range

drivers. The production history of the Alpair 10 series is well known inside purist audiophile

circles. However this is the first time that a paper cone version has appeared in the 10

series.

The cone is the most radical shallow design Markaudio has produced so far this size of

driver. To maintain its stability, the materials used include an arrangement of glass-

reinforced fibres. The dispersion characteristic is ultra wide. The 10P is frequency range

capable to +25-kHz with an efficiency of 89.5dB. These efficiencies were achieved by

considerable design efforts to reduce mass. The 10Pʼs power train under moving mass

conditions is less 5.2g while retaining Markaudioʼs “long throw” design feature. The coil

winding is “high stress” type forming the tight band arrangement on its body. The result is

one of the lightest coils deployed is this size class, weighing under 2.2g.

The power-train suspension compliance is extremely sensitive. Capable of large extension

for this class of Full-Range audio driver (7-mm 1 way, limited by the Arrestor).

The Alpair 10P is “purist” technical driver. Its purpose is to serve the audiophile and

experimental markets. Due to the highly emittance sensitive power-train, this driver will

need users to take note of the need for high quality lower power amplification and

audiophile level source. The Alpair 10P should not be considered as a “general purpose”

emitter.
