Mark Audio Alpair 10

Mass-Loaded Transmission Line

Last Modified 7/11/12

M10-A10

The M10-A10 speaker is a mass-loaded transmission line with a nominal length of 40". The Alpair 10.2 driver has built in baffle step correction and with a Xmax of 8mm, this driver can be run low and hard (within reason, of course) like no other  5-inch class  driver I have encountered. As with all of my speakers, this speaker is designed to reproduce the more intimate genre, Baroque and early classic, jazz trio and female voice, although they handle the larger forms quite credibly.

The Alpair 10.2 gives you the detail you would expect , yet it does not have the tizzy sound that many metal drivers have. This speaker works well with standard solid state and T-amps. 20-30w/channel is recommended to maintain proper dynamic headroom
