[QUOTE="Timo Beckman, post: 51180, member: 1173"] Re: 2 days of looking @ transfer traces Just the first 1 . After that the array but for setting x-over filters and the rest of the processing just 1 . The grill is off because we changed the original low driver for a other model so i had to redo the first settings . After that the array but in a small room it's not really a good idea to take that as a reference . If the mic gets to close to the array you start to see multiple speakers specialy in the phase response . Also because off the walls being closer to the array than in a concert hall the reflections are a lot stronger in level and it gets pretty hard to make sence out of the measured response . The first setting of this array saw action about a month ago (and the alignment stil held it's ground but a lot les coherence) but there were no down fills available at that time . With this measurement i tried to get as little delay as possible in to the system and stil a nice phase response with not to much processing and we wanted to see if the settings could be used on the down fill . Also instead of delaying the sub i used a 1st order allpass (so 90dg of phase shift) higher up the frequency scale and that also worked pretty nice . In a large venue with the array way up above i probably would end up using delay again but we will see when it happens . [/QUOTE]
