[QUOTE="Ivan Beaver, post: 108294, member: 30"] Re: tall skinny speakers "Measuring" can take on very different meanings. It is one thing to simply measure on axis and get a freq response-that is real easy. But that is only 1 small part of the whole puzzle that even begins to describe the behavior of a loudspeaker. Where the "issues" start is what happens OFF AXIS. THAT is where the lobes start to show up. Or how well does the rated pattern hold up over freq? THOSE are the things that people don't like to talk about-and are a bit harder to measure-especially compare. How/where were the measurements taken? It makes a difference. TO what resolution? THAT is a big one. When you are talking narrow vertical coverage (say 10°) you HAVE to measure at least down to 2.5°/ If you don't then there is no way to begin to catch the character of the loudspeaker. 1° would be better-but even 2.5° means a lot of measurements (145 in the vertical plane). You measure ) twice for those that are counting. The average "measurement person" is simply not setup to do that. [/QUOTE]
