Actually, we don't own QSC speakers. The group has Fulcrum Acoustic CX12s that they brought from their old home. I hung them on scaffolding roughly where they might be. I didn't bother to tune the room, just unleashed them as is because I didn't want to waste my time. The front 3rd of the house, empty as it is, was actually decent. The middle 3rd was muddy, the back 3rd was a badly mixed high school dance. The first comment was about the bounce off the balcony which they actually understood. The second was "Boy, imagine that if we could get a few drivers to match those speakers..." Overall, though, it went better than I expected.I'm also feeling that there's probably a good amount of politics going on with the decision making by management.
Since you did a demo with what I'm assuming are the QSCs on sticks, would they be open to hearing other demos by local distributors?
Also, how are you going to try and convince them of improved acoustics? Maybe you could rent a couple legs and hang them at 45s in the back of the room so they can hear what it's like to add some absorption?
They're not against purchasing, but there is a limited budget. And I'm not totally dissatisfied with the current speakers, they just aren't what the room needs for the moment. There's plenty of room on the amplifier for more, but I explained that more isn't always better, and I think they're understanding now. Looking at pdf drawings and listening to "experts" sometimes isn't as good as actually hearing and experiencing.
Now, the demos by local distributors... That's like finding a leprechaun riding a unicorn around here, at least reputable ones.
