Man, those some big boxes. I haven't heard a pair in years. Very common as part of a sound reinforcement system in the early days. I suspect the aftermarket for crossovers could raise the bar. Also wonder if a sub would make sense at some point to give you the bottom octaves. The hard part will getting them past your spousal unit with a 'nah, no big deal, they disappear into the decor.'
Go for it!
