Intermodulation test

Hi!
How to test the inter-modulation effect. [note, works only on 2-way speakers]


- Set a 12db filter in your player as shown: 300Hz, Q0.5, -12dB

- Open a signal generator ~ 60% vol. Drag it to the left until it goes silent. Hit stop.

- Play the song now without bass.

- Play the generator on and off without looking and if you hear the mids get restrained, look at the generator.

- You got to nail it 3 times to get a trend.

(I did it on active speakers and this may be more sensitive).
