Amazing how many people responded that don’t own, and never did own, Aria 936s. Guess what? I do. The Focals will be a huge upgrade over the Klipsch metal driver speakers you have now ~ better tonality, better low-end, more detail w/o the metallic-sounding high end. In your room, they might be a trifle bright, but if you are willing to put a second [large] area rug under your couch, it will help tame the highs, although I agree w/others who’ve already said, at the very least, get some curtains over those windows. I am NOT a fan of metal tweeters, as a rule [I have three setups, and the other two have soft domes], but these are highly detailed w/o the usual "metallic artifacts" of most other metal tweeters which I’ve heard. If they do prove a little bright in your room, just a bit of judicious tweaking of whatever EQ option you have on your receiver should be adequate ~ that’s exactly what it’s for.

Let me know how it goes for you!

I love the Aria series. I bought (on trial basis) three of the Focal Aria series models - 906, 926 and 948. The 906 was amazing and I wanted more. They went back and I had the 926 and the 948s delivered the same day.

I had a tough time choosing, but ended up keeping the 926s. I use stereo subs. The 948s were overkill with subs and for my room size (14’ x 21’).

The three models I bought sound very much alike. All four models have the same tweeter; it’s made of Boron, not Beryllium. The 926, 936 and 948 also all share the same midrange driver, so the differences are basically cabinet size, woofer size, and I would imagine some crossover changes.

I didn’t try the 936 but I can’t imagine it being much different from the others.

Oh about the prices: this speaker lineup has been around since 2013, and they stayed pretty cheap until recently. Yes, inflation’s part of it, but they are a quite a bit more expensive than they were two years ago.

I think the Arias sound wonderful. Smooth as butter. I don’t find the tweeters harsh at all but I do prefer slightly bright speakers. I have Kantas in my big room - I love them too (though they are fugly - the Arias are so simple and pretty), although it seems lots of folks find them to be too bright as well.

The advice about toe-in is spot-on. Arias prefer very little of it.

Hope this helps.

If you get the Kantas, I highly recommend the Gaia II footers. They improve the bass tremendously.  I recently sold a pristine used pair with the Gaias for $6500. Look for a clean used pair and go with the higher end. They look so much better.

The tweeters are some kind of aluminum/magesium mix with Poron used for its suspension.

I too find the Aria series quite nice. Almost bought a pair of 948's awhile back. Went with an older model ML stat instead.
