Let me start out by saying I have almost no audio knowledge. Being deaf in one ear and having hearing loss in the other my whole life. However my wife really appreciates quality sound equipment. So I'll cut to the case I'm looking to buy her a set up for her tattoo shop and I need advice what speakers and now many to properly set it up. The space is rectangle 14 x36 so 504 sqft. There is a pair of 3ft sliding doors In the middle of the space that are open all of the time on less there is a intimate piece being done. My concern is the length of the room and also having speakers in both spaces for when the doors are closed . My initial idea was two play 5 and a sub but I don't know if that would be adequate for the length of the room. It also seems that I may need at least 3 speakers to ensure the tattoo space is cover when the door is closed. Maybe even 4? How would you guys configure this space?
