Product information "Markaudio Alpair 10M Gen3 Gold"
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.
