I always felt attracted from Wisdom Audio,i never saw and listened,but found strange in 6 years in this forum no one spoke about Wisdom,owned or listened
I am an owner and a listener - and I highly biased one at that.
There is a (short) thread on WBF on Wisdom Audio. WBF is primarily well attended by 2 channel audio enthusiasts, and, for the most part (but not exclusively) Wisdom speakers are used in multi--channel music systems and home theaters. Few of their products are meant to be installed "in-room" and thus, 2 channel purist/aficionados would not have much interest. I will say that the Wisdom LS3's and LS4's (and a couple of other Wisdom speakers) both come (I believe) as in-room options and they do some things that no other speaker I have ever heard does. The drivers in the Ls3/LS4 are all PMDs (Planar Magnetic Drivers), that are configured in a true Line Source but instead of me typing all of the pertinent information,
HERE is a link which describes the PMD technology.
HERE is a link to a description and advantage of true Line Source speakers.
And HERE is the link to the short WBF Wisdom Audio thread, if interested.
