Horn resp acoustical power window

[peterjohnswindley]

Hi there.

I've looked at the previous topics on Horn Resp and cannot find the definitive answer to the following..:

Does the 'acoustical power' window of horn resp tell you the 'shape' that the horn loading is adding to the manufacturer's curve?

Or is it giving you its prediction of the actual frequency response (presumably 'measured' at 1m on axis)?

Thanks
Peter


PS thanks to all those who have contributed to my previous questions!

No.

It is giving you the predicted power response (as distinct from pressure response) at 1m. Because it is power, directivity is not factor, so the result is the same at all angles.

Google 'loudspeaker power response' for more information.
