I bought a pair of Triton 2+ speakers about two years ago. I've since sold them because I decided to move my audio system to a much bigger room, and I wanted to upgrade.
I haven't heard the Aria 936, but I did audition the Kanta No 2 when I was shopping for the Triton 2+. I liked the Focals but thought the Triton's delivered more performance for the money. In both cases, the dealers offered me about 20% off retail. The Focals were a little thin in the bass for my taste although the top end was more detailed than the Tritons.
I lived with the Tritons for 15 months of so before selling them. For the price, I thought they were a very nice speaker. I had them in a 13'x14' room - about 3' from the front wall and about 8' apart. Being able to adjust the bass level made if easy to dial in a good balance without overwhelming the room. I did have tube traps in the front corners which help reduce the room modes.
Overall, I thought the Tritons imaged very well and had excellent bass performance. The SQ got somewhat weaker as you moved up the frequency range. It wasn't bad, but they lacked the clarity, smoothness, and sparkle of the best speakers I've owned.
If the Aria 936 is anything like the Kanta No2, I'd say the Triton 2+ would be a much better choice for home theater, particularly if you like action movies. The Focals were great with jazz and vocals, but lacked the punch that the Tritons had.
