Moderator,
For years, I've been happy with an XXL Supercenter and Triton ones with Supersat 60's as surrounds. All had been room corrected with ARC 2 and your advice on the forum for appropriate crossover settings. I've recently upgraded to the reference Supercenter and have felt the upgrade was worth it. Coincidentally Anthem just upgraded to ARC 3, which I feel also has been an improvement, but wonder if your recommendations for this combination of reference center, and triton ones changes any previous advice on crossovers?
Just as an FYI, the reference center upgrade has for the very first time allowed my wife (who is hearing impaired) to watch movies without subtitles. It's quite liberating. She felt ARC Genesis improved it even more.

That's great news about your wife's ability to hear this system better!

While there are sonic improvements to the new center, the crossover frequency recommendations are pretty much the same, so no worries there.

Sounds like a win win for you and your wife!
