[QUOTE="Dick Rees, post: 63991, member: 16"] Re: Question concerning "end fire subs" I'm replying to this post as it appears that I can't reply to my own: Final after the gig report: I ended up not using the Cobra II rig due to the promoter not seeing the value-added in upgrading the rig, so I used my 4 EV T-251+ mid/hi's augmented with a pair of Sx300's as a separate "solo PA". SOS all the way with the 300's above the traps and tilted down using toilet shims. Subs were the "End-fire 2" arrangement resulting in a nice, full cardioid delivery out front and very benign bass on stage using 4 Sb180's. The entire system was delayed to the backline except for the solo PA which was delayed to the front of the stage (roughly). It worked extremely well, aided by a 20-25 mph tail-wind which carried the sound forever down into the next couple of blocks with the entire mix intelligible, albeit lacking in LF content the farther out you got. But I'd say the complete mix went well over 150'. SPL @ FOH (75' out, A slow) was hitting 103 at the peaks. That checks out with the speaker specs and the math, so that's about as good as it gets. All in all I was very satisfied, especially with the subbage. Thanks to all for the advice, constructive criticism and general support. DR [/QUOTE]
