Yes, generally LCR just refers to speakers that can allegedly be ideal for LCR use
The center design often suffers, tho. They also had a line labeled "LCR" too that I found with 4 inch drivers, and those I'd just move on from sooner than later except perhaps in a very small room....but those are different from the T1+ and other models you mention now....in any case not very familiar with Emotiva stuff (their electronics haven't been too attractive), and not now as likely to recommend changes there primarily. The T1+ are floorstanders?
