This is a large part of the beauty and superiority of Bose products. In the last few years, a significant number of musicians who perform in small clubs and bars (myself among them) have switched from conventional sound amplification systems to the Bose PAS. The sound quality, in every corner of any venue, is unparalleled.
Most sound reproduction/amplification systems are stuck in the middle of the last century. Instead of radial/omni-directional sound distribution allowing all in a room minimal dependence upon indirect sound waves, no matter their orientation/proximity to speaker cabinets, conventional systems produce isolated (and rarefied) cone-shaped "sweet spots" that only a few in an audience are allowed to experience; particularly, if stereophonic sound is produced.
Quality of sound is another huge factor. Without exception, audience members remark that, unlike the rest of the band, my bass guitar cuts through to the back of the room as clear as if they were in the front. They most often attribute this anomaly to my instrument or playing, but the effect is due to the Bose PAS.
