How do you like those 23s I thought the 6s were the best KLHs but then read someone saying the 23s are even better, just not as well known.
I've never had sixes but I love my Twenty Threes.
A couple comments:
1) the sweet spot with them is much narrower than with an EPI or Genesis speaker with the inverted dome tweeter.
2) The bass isn't QUITE as deep as I get from my Rectilinear III lowboys.
However, if you had to live with the Twenty Threes as your only pair of speakers for the rest of your life, you'd still be doing reasonably OK.
