I’m looking for suggestions on the “optimal” crossover settings on my receiver. I have an Onkyo TX-NR676 receiver. My center is a Klipsch R-25C. My fronts are Klipsch R-28F towers with twin 8”. My surrounds are Klipsch RP-140SAs mounted higher angled down. My sub is a Klipsch R-12SW. I am running the sub using the single cable and the LFE setting which I hear is definitely the way to go. I also know that 80Hz is the THX recommended setting on all speakers, but that’s generally for smaller bookshelf speakers. Thoughts or suggestions?
