full range speakers is complete marketing and nothing else period!! Most (98%) of the best speakers in the world (cost no object) are designed to not be full range but to cover a lesser range with better sonics. This of course in the lower octives and not the high frequencies. Even though many cannot hear 20 or even 16 there are harmonics well above 20 even 30 that do effect the lower ranges that we can hear. Deep bass however is a problem in many situations and thus avoided by the better speakers. Room nodes to just name one. Room size to name another. If you do not listen to organ music, then any response above 35htz will be fine for most people- I did say most. Those wanting 20htz bass would do better with one or two subs anyways than to try to get it from two evenly placed l/r speakers that just cancel out deep bass at the listening seat- the bigger the speakers, the more bass that is canceled-proof? Just check out The Absolute Sound back a few issues. The biggest mistake in all of the high end, in my oppinion, is that people buy way too big of speakers for their room size!!
