Loudspeaker frequency response dip I'm using a kit I put together...so I'm possibly missing something fundamental. The measurement chain is roughly: generate MLS signal->output to soundcard->amplify->playback with loudspeaker->record response with mic->extract signal from mic power supply->convert to digital signal with sound card->circular convolution->system response. I also account for the sound cards response. Adding a LPF to the signal reduces the dip, so does adding fibrous material infront of the loudspeaker to reduce the higher order modes. I will look at trying a different excitation signal. |
