[QUOTE="Ivan Beaver, post: 55636, member: 30"] Re: High output main speakers. I would be very careful using different speakers in the same array-ESPECIALLY if they are trying to cover the same area. The reason is the phase response. Just because they are both "behaved" does not mean that they are similar. I was going to do a gig a couple of years ago and I knew it was going to be LOUD!. So I was going to use a Sh96 on the bottom and a pair of SH46's on top. Basically covering the same area-but the 96 would provide wider coverage up close-while the 46's would provide a loduer sound to back of the room (and be little further away from the people up close to provide a bit more even SPL). While playing around in the warehouse-no matter what I tried-I could not get a decent alignment. Either I could get below 400Hz to sum well or above 400Hz. But not both at the same time. This was due to the phase response being different. I ended up just using 4 46's per side-2 over 2-and it worked well-the cabinets were just loafing along. The subs were "out of gas" long before the 46's. This was doing 126-128dB SPL C-fast at FOH. I used Sh50's as front fills-and that worked out well-as they were covering a totally different area than the 46's. I knocked the low freq out of the SH50s (there was plenty of that coming from the mains) to where the pattern control on the SH50 was keeping the sound where I wanted it. [/QUOTE]
