@kota1 "Gone in 60 Seconds " was a big movie we shot in Long Beach Ca for nearly 3 months at night and about 2 months in other locations, it was very grueling.
I think @thespeakerdude is for real, I don't know the audiophile world yet but I do know the physics of sound and he gets that right.
I saw your thread on sound measurements, curious as to why so much info on SPL and so little info given by way of frequency polar patterns?
