[QUOTE="Chris Burns, post: 214863, member: 11386"] Thanks Peter. Appreciate the response. Im ready to start cutting panels so I just want to ensure Ive got this nailed down before I commit. How did the 40 degree * 3 splay play out in testing? I imagine the increased overlap of 10 more degrees was still acceptable? The overall coverage then would be 160 degrees? If you ever have a chance to do a field full range sweep of one and then the two and three together to see the combined responses that would he fantastic! So it would then be acceptable to center the 12” drivers over and under the centerline of the Ciare? I noticed in the other box 3d design it was this way. So if we came straight back 90 degrees square off the baffle 2.5-5cm (min length needed)and then angled 25 and 15 to keep the drivers centered on the baffle, will this be detrimental to a defree noticable due to upsetting the close proximity of those horns in your splay coherence with those horns nearly side to side? I’m totally fine with building a pair each side of these for 100degrees as exactly per your design, I dont think Id ever have a use for the triple per side for 160degrees, although what s great is I can always add side fills or build another pair for an outdoor wide venue. Im going to test the first box built with the 464 and also a 4594 (These I have) and also going to pick up a DE1090 and the new Eminence 314X. Id like to see the response and performance with all three. The two standard comp drivers are happy at a 700hz XO, and Ive heard fantastic reviews of that new 314X. Of course the two coaxials will always sing better than a mono driver, but I just want to evaluate the difference. Going with 12NDL88s. Sent from my iPhone [/QUOTE]
