Acoustic timing reference. Question-proposal.

[sm52]

@John,
hello. Question-proposal on acoustic synchronization of measurements. Sometimes, for some reason, the frequency of the preliminary high-frequency signal is not very well reproduced by the high-frequency driver, which is selected as a reference. Or it is not possible to use a separate HF driver. Or this frequency is played by two drivers - mid and tweeter together. Can the user be given a choice of the pre-tone frequency? Or there are several options to choose from, such as 5 kHz, 8 kHz or 10 kHz. Or from some range, for example, 5 kHz-12 kHz.

The timing signal is not a tone, it is a 5 kHz to 20 kHz sweep.

Are there any difficulties if everything happens like in my quote?

Not usually. The main risk is from unusually strong reflections.
