Everybody knows I'm a fanatical line array fan, so keep this bias in mind when I advise you to build the LS-9's instead. I haven't heard them, but I anticipate they will excel in the ability to create a "you are there" impression of the music.

Your wife actually likes big speakers? Wow! Every man knows the coolness quotient of a speaker goes up with its size, while every woman believes a speaker is a thing of unspeakable ugliness to be made as small as possible and hidden behind a fern on a high shelf. Your wife and mine are two of the few exceptions. We're going to the RMAF together, and I plan to send her on an errand to distract her while I hear the LS-9's so she doesn't insist that I build a pair and buy a bigger house with a large listening room to use them in:)
