Alpair 10P, 100mm Fullrange drive unit 6ohm single ferrite magnet, Legendary full range drive unit, 5in Natural blue paper cone, Operating range to 25KHz – very linear response, Low-profile multiform cone for broad directivity pattern, Advanced low-distortion motor design, Long-stroke suspension with arrestor and progressive-rate spider, Self-damping reinforced polymer basket. 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 glassreinforced 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 10P?s power train under moving mass conditions is less 5.2g while retaining Markaudio?s “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. Pulled from DIY speakers. Sold as is.

2pcs = 1 pair! Black friday offer!!! New Markaudio Alpair 10M full range driver pair. This item is made specially for Finnish Unmonday company. Difference is missing stickers, otherwise Drivers are identical to retail ones. Delivery includes Bezels, these are made by Markaudio but printing differs from original. This Alpair 10 Gen.3 is the latest model in a development line designed to extend the performance of mid - sized Markaudio full - range emitters. This generati on of Alpair 10 utilizes a new ultra thin wall coil. Together with a new modification to its cone, this latest model delivers usable frequency range up to 25 - kHz while retaining the “purist” single - cone design, This driver retains the Multi - form cone tec hnology with a new more efficient profile giving improved high range performance. Additional features include an advanced Nomex super -light rear suspension (spider). The Alpai r 10s frame is formed from a new mix of polymers, making it 5% stiffer than the old model. The Gen.3 version houses an “Arrestor” in its magnetic motor sub - assembly, helping to avoid damage from over - load situations.

Mark Audio Alpair 10P 6 paper-cone full range drivers in excellent condition...see pics. I bought these a few years ago and used them for about a year. They have not been overdriven or abused in any way and should be as good as new. Current retail price is $220/pair. Specifications Includes the original terminal connectors, mounting screws, boxes and packaging. I will double box for shipping. Free economy shipping to continental USA only. Thanks for looking.
