I must agree with "russbutton" and those below who have suggested the Linkwitz LX521’s and Orion’s - they are truly superb speakers and incredible values. I have the Orion 3.4’s, and there are very few speakers for less than $20K+ that can match them.
Yes - they do require amplification of 8 channels (4 right and 4 left), and an external custom crossover - which may be either analog or digital (most seem to prefer the analog crossover). There are several sources for these - you don’t have to DIY. But, that additional complexity yields almost unmatched sound. And... for the record... a digital crossover, does not require a digital source.
The Orions do appear on the for sale forums (usually with the ATI 6012 amp) every now and then.
Oh yes... I’d like to have the Legacy Audio Aeris as well - which nothing bests for less than $50K. But... I don’t want to invest that amount of money, and don’t want to have to have the neighbors over to help me move my speakers. The LX521’s and Orion’s are much easier to manage - yet their sound rivals the Aeris.
