Mike, As a bass player, I'd love it if there were such a thing as a linear loudspeaker, but sound is, by its very nature, non-linear. It takes a great deal more energy to reproduce a 50HZ tone at any nominal db level than it does to produce a 1KHz tone at that same nominal db level. db is a non-linear scale, and the speakers you term "linear" are in fact ones that produce a flat frequency response measured in db. They're subject to a power curve. Various useful analogies can be made between digital audio and digital imaging, but this is not one of them.
