Re: Thoughts on old EAW KF gear
The vertical pattern needed for a particular application is going to depend on the mounting height and the amount of SPL variation that can be tolerated.
It is true that if you use a narrow vertical pattern there will be less energy going to the ceiling-a good thing. This is the "general statement".
HOWEVER there is not way to get even SPL from front to back. This is the overlooked part. If you put the loudspeaker down low-then it is going to be louder in the front than the back. If you put it up high, then you have to choose which section of seats are going to be covered-front-middle or rear. Yes you can add additional loudspeakers for more fill-but now you have increased the "effective" vertical coverage (although it doesn't work that way). And now you are talking about a SYSTEM-not a single loudspeaker.
I never said anything about bypassing the laws of physics. I said that we move the wider coverage loudspeakers closer to the audience-so they are putting the coverage on the audience-NOT spraying it all around.
A riddle. How do you take a single speaker and have nice smooth coverage everywhere? That is what people want-right?
Build a room out of glass and point it in the upper corner. The coverage will be pretty much the same everywhere-that makes for a really nice looking coverage map.
HOWEVER-it is going to be totally useless in terms of clarity. So now it is time to look a little bit deeper.
By "general" statements-I meant things that need more clarification. Just like with cars. Go to a local autocross event. The cars with the larger horsepower go aroudn the track faster-right? But just wait till the little go carts go round. They are faster-handle the corners better and so forth. But they have very small engines.
Yes there are big differences between the cars-but in THAT event-the idea is to carry a single person around the track as fast as possible. And they do it with the smallest engines.
Just sayin' that often a bit more definition is needed to a "general" statement.
