I believe it was $275 a pair for M3s in the distant past when the Canadian dollar was well below parity with the US dollar. We have made a lot of improvements to the M3 over the years. The woofer, tweeter, and crossover have been through a few redesigns, there are T-nuts and bolts in place of the wood screws, magnetic grilles, and a plethora of other little improvements. We would never give up that smooth midrange that makes the M3 such a great loudspeaker though.
