Ya a line array shoot out sounds great aa
But lets make it 100% fair in all spectrum's.
The contestants bring them to a room at RMAF ,not each others room's as we know as a fact some people dampend the heck out of the rooms and try to control the room issues with absorption the best possible and this would not be fair.
Back to the test room or shoot out room.
One of the rooms at RMAF not the smaller rooms but not a ball room.Why, well in the real world people who are purchasing but them into there home not a custom made ball room

Lets say the room which has a bed room off the right and has a good size listening area and this bead room would be a great spot to place the line arrays when not in the room and behind a cloth. This will give people a idea with out the line array's being a small room or a ball room .Plus how the line arrays work in the room this size.
And the room would be treated, which all parties have no say in brand nothing.They bring in the speakers and sit back.Nothing more.
Electronics would come in 100% un bias.
Selected last minute from someone at the show not related to any party who has a Line array in the shoot out.
How does that sound.
And open to all not just Rick and Danny
