65-RT for multiple side channels or wait for 65f/x-RT

wolfman1138

So I am building a multi-row theater and I need to know if I should go with 65-RTs or wait for the 65f/x-RTs to be released.

I will have three rows of theater seats that are between 42" and 46" backs (still working on final plan). The theater is 13.5' wide and 24' deep.

Am I better off going with three of the direct firing 65-RTs or wait for the bipole 65f/x-RT and run with two pairs?

Thanks in advance for helping with these final details.
