This Alpair 10 is the latest model in a development line designed to extend the performance of mid-sized Markaudio full-range emitters. Measured performance is extended. Vas increases from 21 to 28 liters. Fo is now 36Hz, 4Hz lower than the old model. Total Q increases to 0.33 making this new Alpair 10 usable in larger audio applications.
This driver uses an all-new Multi-form cone design and U cap with a new more efficient product giving improved high range performance. Additional features include a new advanced Nomex super-light rear suspension (Spider) and a special Aluminum rectangle wire wound coil, both reduce the mass of the power-train. The Alpair 10's frame has a new mix of Polymers for the frame, making it 10% stiffer than the old model. New connector sets allow for remote soldering of cables, installation is easy.
