This lady is exhibiting for the first time and has asked for help with the Gun Room. She has built her own kit and is asking for help with how to set it up in the Gun Room. Pic’s of previous setups and advice.
There is a relatively deep beam that runs across the room about a third of the way in from the opposite wall from where the speakers are shown in the above pic.
This has caused some bass issues in the past. Experiment with speaker positioning.
There is also a door that leads into the Butlers Pantry.
Make sure it is shut and is not used as a route from one side of the show to the other otherwise you will be exhibiting in a corridor.
