[QUOTE="Mark Wilkinson, post: 149090, member: 8989"] Re: 60 Degree DIY Mid Hi Hi Don, the latency is about 75ms. But this is an overkill first run at, ...... 'see what can be done at the limit of the processor'. I mean I'm using maximum taps, and reaching into steepest x-over topology.... So there is a lot of room to cut back latency. I think [B]alot[/B].....and without changing phase or amplitude curves much. At this point, getting a feel for the cutbacks available, I'm guessing optimal sound quality vs latency, lies in the 25 -30 ms range. I'm thinking this gets phase flat on the mids down to 80hz, and subs from 80 up... IOW near perfect summation and flat phase from 80hz up...while needing to let natural sub delay below 80 be what it may be... Only more testing will tell...
