Canes, you may as well do your room right the second time. Make the room anti-standing wave by building non-parallel surfaces. That means a tilted ceiling, and trapezoidal walls. 14 foot thick insulation on the rear wall with no drywall will do wonders for bass. As for wiring, you want to come up with a system that allows for future flexibility. You may want to do 16-channel down the road.
Commission Ian to build you on-wall and on-ceiling active LFRs for all channels.
An equipment room would be ideal because you damned well know you'll be running ADA-1500 amps for every channel in the future.
Make us proud, man. Trevor will guide you.
Edit: I heard the Algonquins and they are very good for outside. Maybe the v4 are even better if they have a "real" cross-over like the M3v4. It would be awesome to have an 800 out there too. Ian can build you a weather-resistant 800 with a splash shield over the amp plate and resin epoxy over the cabinet. A one-of-a-kind! Make sure Ian signs that one.
