Good question ! If you have 2 speakers side by side, facing the same way, they better be in faze, meaning, when 1 speaker is producing a positive pulse, or negative, the other 1 better be doing the same at the same point in time. If not, when 1 speaker is pushing air in 1 direction, and the other is pulling air in the other, there will be a stalemate, or a cancelling out of each other. Obviously , there is not a complete cancellation, because some sound is there, but much of the sound is missing. ( mexican standoff ) Had an organ once which didn't seem to have much volume, and the dealer thought that there must be something wrong with the amplifier. Well I checked, and everything seemed quite normal. I then checked the speakers, and found that they were hooked up opposite to each other. Soon as I reversed the leads, the organ increased volume to almost double. The dealer thought I was a genius, [and I didn't tell him any different.] People who pay you money , should be allowed think what they like, noooo ?????
