Another question, how many tiers of seating are you planning, 1 or 2? You’ll want a multi-polar type speaker for side-surrounds and maybe the rears also. You need to be careful with Klipsch, skip the F3s. If the room isn’t appropriately damped, they will be harsh sounding. For better bass response, you might consider a dual sub setup, but a good single sub should be less expensive. There are many good speaker options available also from ACI, Ascend Acoustics, Aperion Audio, Athena Tech, Atlantic Tech, Axiom, Boston Acoustics, Dali, Definitive Technology, Energy, Focal/JM Lab, HSU, Infinity, JBL, KEF, Martin Logan, Monitor Audio, NHT, Onyx, Paradigm, Phase Technology, Polk Audio, PSB, RBH, Rocket, Sonance, SpeakerCraft, SVS, etc.
