Here's my setup:
Front: Rti100 x2
Surround: Fxi30 x2
Rear center(s): rti38 x2
ATM rti70 is for $399 at CC here and I got rti100 for $159 each a few days ago.
I saw rti70 as DEMO piece and salesman said he can get open box pricing for those...but after a few minutes he said he can't get any discount on rti70 at all. :(
He said.."rti70 is still in production"
