Why so many pro audio setups as compared to numerous car audio speakers?

[QUOTE="Cliff459, post: 8259650, member: 660957"] You gave some great examples here of why "more is better" just does not apply to car audio speakers. Putting large groups of speakers together with no regard to physics is a recipe for disaster. I did concert audio for quite a few years and trust me, even when speakers are purposely designed to work together there's still a LOT of issues to sort out. The specialized EQ applied to large concert arrays is crazy and difficult to do even with the very expensive DSP processors used in that industry. "Pro Audio" drivers are efficient (high SPL per watt of input), rugged (high power handling), and therefore require just a few units to do the job. This avoids the physics problems that come from large arrays of drivers as an attempt to achieve SPL. One thing that seems to do OK by using a "pile of speakers" is subwoofer applications, because the longer wavelengths from low frequency waves don't cancel when placed relatively close together. A 60Hz wave has a wavelength of almost 19 feet, while a 6,000 Hz one has a wavelength of 2-1/4". This means that there will be high-frequency problems even putting 6-1/2" coax speakers right next to each other. [/QUOTE]
