Polk Audio 80F/X-RT in-Ceiling 2-Way Round Surround Speakers White, Pair (Renewed)

we have a five one audio system for the living room i purchased the polk audio 80 f slash xls for the front three speakers right center and left and purchased the polk audio 80f xrt for the two back speakers right and left the house is a new build we ran the audio cable and used the 9 3 8 diameter pole pre-construction brackets before the drywall went up so installation was a breeze i rotated the speakers towards the listening area and added the polk dsw pro 440 subwoofer we have been listening to them from about a year and are very happy with the purchase both the small diving wall and the 15 feet vaulted ceiling created a challenge for adding a pair of rear channel speakers i choose these polk fxrt speakers based on size price compared to sony's episode and to also timber match with my front towers wow i am pleasantly surprised although the priority here was for surround sound effect
