Is there a "standard" height placement (or requirement) for the Atmos RP-140SA? Everything I see reflects that it is designed to sit on top of floor standing speakers which puts them just above the listener's ear position. I'm wondering if there is impact to the audio in relation to speaker height relative to the listener. If the atmos speaker is at or below the listener's ear position I wonder if it would cause the listener to hear the audio directly from the speaker rather than the reflected audio from the ceiling. Due to a bulkhead partially above my right floor standing speaker, I worry it may interfere with the intended ceiling reflection. Therefore I am considering placing the front two atmos speakers on my AV cabinet about 5 feet apart and approximately 24 inches from the floor (measured to bottom of atmos speaker).

To add to my confusion here, my KF-28s replaced Klipsch Synergy B-3s (bookshelves). I am debating about using the bookshelves for either front height or back surround (already have side surround). I have read that if you go front height speakers you want them to match the center speaker, but don't know if that is true. If it is true and front height is the best option here maybe I should keep the current center channel. Still debating if either option is worth it (front height/rear surround) as I'm not sure how much content is available to take advantage and this is getting into a whole other topic than my original question. However, still pertinent as I try to make a decision on my next improvement. My focus is on the center channel (C-2) because it has always felt like the "weak link" in the system even before getting the floorstanding fronts (KF-28s).

Thanks for the reply and info! Yes, I have seen the KC-25 fluctuate a lot between $99 - $129 lately so definitely inexpensive compared to other options. The KF-28s are new addition for me so that's what started all this. When manually calibrating as I move from Left Front to Center to Right Front the Left and Right sound identical, but you can tell the center sounds slightly different. I've tried researching a lot on HT setup, but honestly there is just too much info/opinion out there these days to make an educated decision from it. I'm hoping someone experienced in HT setup on here can chime in and help guide my next step. I get the whole matching of speakers within the same manufacturer, but get lost when it comes down to trying to decide if I should stay in the same "line or series" within the manufacturer or if I can/should move up in quality. When I read about "timbre" matching of speakers I'm not sure exactly which numbers in the specs I should be concerned with/comparing. I do understand from what I read that I should try and match the tweeter across speakers (all aluminum or all titanium, etc.). I'm not sure about if the woofer material should match too.

Seeking center channel best option for my KF-28s. I currently have a C-2 as my center channel, but am wondering if I can upgrade quality, but also match the KF-28s? I believe the KC-25 would be considered the best match for the KF-28s, but will this even feel like an improvement from my C-2 feeling like money well spent? Are there other center channel speakers that could match and would be better quality than the KC-25? Replacing the KF-28s is not an option and likely doubt will ever be replacing them. Thanks in advance for your help!
