I am very familiar with both and I do not sell either. The Marten Coltrane has a more real sounding midrange and tweeter. The inner detail and dynamics are also greater than the Rockport Hyperions. It is however a much smaller speaker and cannot move quite as much air as the very large Rockport Hyperions. The Rockports have a very nice musical sound, however they are not as dynamic, nor do they go as deep as one would expect.
BTW, The quality of construction on both speakers is top notch.
