The speakers will do themselves proud.
Building a sound isolated, portable screening room for a trade show is a b***h. An expensive one at that. The guys have been busting their backsides night and day to get it constructed and assembled and several parts of the original design have been changed on the fly ... did I say expensive? (not to mention the changes dictated by the Fire Marshall and Convention Authorities structural approval people). Even family members have been pressed into indentured servitude.
The doors, OTOH, are beasts. On top of all of that, the convention people charge by the pound to move the "stuff" into the display hall. You ought to see that bill. Crud. Regardless of how the room performs, the speakers will do very well.
Other companies who've supported this project include Stewart Film Screen, QSC Audio, Meridian Audio, Runco, Richard Gray's Power Company, THX, The Soundproofing Company, Crestron, and others (I'm sure I'm going to annoy someone for not listing them here).
In any case, come over and listen to Procella. (Have at it Mark
