I used two pairs of Imagine XAs with my PSB Imagine T2 (and briefly, the T3 I replaced them with as mains) until I went to three pairs of the CS1000 as physical speakers overhead. I haven't checked the upfiring speakers ("DA") thread in quite some time, but back in 2016 and 2017 they got good reviews from what I remember.
I thought they punched above their weight - meaning that you got a convincing sense of ambience overhead on a movie like Gravity or (DTS:X) Independence Day, and they did a decent job of even getting some upper bass from the non-reflected (less direction above you) direct sound. One thing Paul Barton did right with them was to give them a proper angle/waveguide that was part of the speaker design with the grille. There's also both a woofer and a tweeter, rather than the older upfiring height speaker designs that just used a single concentric driver from the likes of Pioneer.
One thing you have to be careful of is placement: you want the base of the supporting floor speaker big enough that the upfirer base can be stable, without tipping over and crashing to the floor
. That's where looking up the speaker specifications on the PSB website is helpful.
Put it this way: if I had a mainstream AVR, I'd have been fine with my four upfirers. However, I ran into some issues with a Trinnov feature called Remapping, where the localization of the upfirers due to the indirect sound being the important one for higher frequencies was a problem. And ultimately I could have ceiling mounted speakers with the CS series in our condo, so I went that route.
