I calculated that your room is 31 feet deep by 21 feet wide by 8 feet tall. Of course those measurements could vary some. That is a big room. I suggest horns and at your budget you could hit the best of Viking Acoustic.
Large room with low budget for speakers
Hey everyone I have been having issues finding the right kind of boxed speakers that would work in my room well that won’t be too dry on the bass region my set up has an array of Rel woofers my budget is 30k but all the speakers that would be big enough would be around 60k and up I have looking into brands like Focal, Rockport, and Wilson audio but none of the smaller speakers from these brands are very impressive in my room
