Re: time correction


The speed of sound does in fact change across the audible frequency, and there are speaker designers (some extremely prominant ones, in fact) who believe that there is a benefit to staggering the vertical alignment of drivers, with the tweeters furthest back. So, "the speed of sound is the speed of sound" is not correct. Of course, staggering drivers only works 100% at a predetermined listening distance.

All that said, I agree with Chuck that your greatest issue is the relative delay between all those mids, which would be a particular problem on the center. Of course, speakers have been designed that way from such prominant designers as Polk and even Mark Levinson.

Also, if you want to dispute that sound speed changes with frequency, or that it takes too great a shift to matter, explain why the sound of a siren drops suddenly as an ambulance passes you. It is due to the change in speed of the sound traveling toward you between the ambulance approaching and moving away from you.
