I'm comparing the KLH 17 to the 4x here and though AR made a 4xa, no model was ever designated the 4ax, so take this with however many grains of salt you will...
The AR-4x has a stronger bass, but a very dark presentation - the treble is AR-reticent, and off-axis downright poor. Probably not as bad a speaker as I'm making it out to be.
The KLH 17 has a more extended high end and generally a more forward presentation. Whether or not you like it will depend entirely on how you feel about the typical Henry Kloss voicing. I find the upper midrange peak artificial and mildly offensive.
The winner? Dynaco A-25. Runner-up? EPI 100.
Concurring, I have studied all of these, and KLH-17 and AR4x(a) are upgrade candidates as documented elsewhere in this forum. KLH-6, also, but they keep their woofers, at least.
Baby Advent II is a well-balanced performer.
Rehabbed another pair of Polk Monitor 5s yesterday, and for whatever it may be worth, with their Peerless tweeters, they, too, get the Zilchster seal.... :thmbsp:
IMO you should go for the AR-4's. With a recap and pot cleaning, they will quickly jump to the top of your list.
There aren't many speakers as small as the AR-4's that can accurately reproduce an orchestra.

Yes, correct.Without doing a thorough search through the forum, can I assume by your above statement that the KLH-17 and AR4x were the recipients of non-stock woofers?
