Quote:Look at the chart I posted. The green line is a single lobe. That's an ideal radiation pattern. The blue line at 15846Hz is eleven lobes, an abominable pattern. The rest of the frequencies are in between the two extremes. If you're sitting inside the lobe you hear that frequency at the same level as you do the 1kHz of the single green lobe. If not, you don't.
As to the value of charts, if you know how to read them, you can tell how a speaker sounds without having to hear it. It's just like being able to read music and know how a song sounds without having heard it, or read a book and know what the words say without someone else having to speak them.
They're also invaluable where fine tuning a system is concerned, as not even the most golden eared audiophile has the ability to hear even 10% of what gear can measure. Getting that other 90% right makes the difference between OK, pretty good, damn good and simply stunning. If you don't care about having more than an OK system by all means don't sweat the measurements. But if you want better than that having the ability to make use of measurements isn't an option, it's a necessity, and one of the first things you do is to use the measurements to tell you if a speaker is capable of more than just OK, or if no amount of system adjustment will ever get any more than that.
