POLK web site describes TCi line of in-wall/ceiling speakers as superior to RCi line but some retailers are selling the TCi for less money. Also, the RCi seem to sell much more widely- I see many user reviews of RCi where with TCi , it is "Be the first to review...".

Preconstruction frames for surrround sound set up in basement are already installed and these are the two POLK lines that will fit in the installed frames.

I am looking to buy TCi since it is supposed to be better but want to make sure it is not the lemon of the POLK line before I pull the trigger.

Tthanks.
