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 generation of Alpair 10 utilises 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 technology with a new more efficient profile giving improved high range performance. Additional features include an advanced Nomex superlight rear suspension (spider). The Alpair 10‘s 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.

Thanks Cal, these drivers are always popular. They’ve been around a while now but we still get many favourable comments about them.

Great drivers. I followed the break-in procedure and now have about 1000 hours on them. I use these in the Pensil design and drive them with the Pete Millett designed DCPP amplifier. I listen primarily to acoustic based music and these are coherent and cohesive with a very good soundstage. They do reveal shortcomings in the music’s production. Norah Jones, Kandace Springs? In the room with me. Miles Davis Dave, Brubeck? In the room. The remixes of Led Zeppelin’s “Stairway to Heaven” or “Going to California” were enjoyable. They are worth every penny.
