Small business subwoofer placement improvement question
I'm re-evaluating the sound system in a small business (as pictured). It's not perfect, but with the exception of the subwoofer situation, it sounds acceptable. The problem is that the sales floor is extremely small and there aren't any logical positions to place any speakers, so I had to improvise a bit (front, center, and rear speakers are colored orange and the arrow indicates the direction that each faces).
The issue is that the forward-firing subwoofer is muffled by the counter that sits in front of it (the three wide blue rectangles are all ~4' tall counters and the small dark blue rectangle between them is a floor-to-ceiling wall) when standing on the area marked in green. My goal is to place it so that you can hear it whether you are the customer at the primary focal point of the room (the green cross) or behind the counter working (the purple cross). I know this isn't ideal for a surround system setup, but I'm just trying to make the most of we have to work with.
Any ideas for better subwoofer placement?
