Hello , im building a home theater in my basement , the room size is about 13x20 . I already have a pair of tower speaker klipsch F1 as front but i think it not going to fit well in my "HT deco". I want to replace them whit Polk audio in-wall RC65I. I want to know if it gonna be enough for the room size i have? And vs my klipsch im gonna loose quality? . Thank you and sorry for my english im french canadian.
