If you don't have a lot of money to spend but you want to estimate the frequency response of different loudspeaker setups what is the best way to do it?
I bought a very nice microphone and built a box with foam on the inside. My idea is to place the loudspeaker and the mic in the box and measure the power level at different frequencies by playing a sine tone at those frequencies.
Or is it better to have the microphone and loudspeaker in an open space where the mic is 10 inches away from the loudspeaker?
I'm sure neither of the 2 methods above are valid for making such measurements (if so please explain why), but how should I do then?
Also, should I use sine tones or is it better to use another test signal like an "impulse", "white" noise or a chirp signal?
Hoping to get some good answers / advice
