Sure your house is big enough - - they are "teeny" speakers. I'm sure the wiring would be fun - - definitely a project for a house under new construction.
Anybody old enough to remember the "coffin" stereo/consoles of the 60's with the turntable, radio and a ga-zillion speakers (which I still do not understand why they did that) with access via an "open lid" look? Those were the days of real "Hi-Fidelity." A couple scotches, some jazz or Ray Charles and the old slam/bam turntable with five records stacked on each other. That's what my folks did as I peeked out my bedroom door. Then again, I couldn't see much for all the cigarette smoke.
I did experiment with a 9.1 (even 11.1) channel speaker setup but it was really overkill. I settled into 7.1 and haven't looked back.
