Wisdom audio D75 speakers ?Speakers for big room?

I have never personally heard them but there is a pair for sale here for $6500 so they don't retain their value too well...

I have heard them and although they did some things well, and looked nice, I was ultimately unimpressed. I don't want to slander the product or specify my dissatisfaction. They do large size relatively well. Nonetheless, this is a speaker that you would want to audition carefully before committing to, and as noted by Slartibartfast, buy them inexpensively, as resale seems to be a problem.
