You can buy a DVM for less than $10.

I'd sure not trust a $ 10 DVM to give me readable levels on a quickly
varying signal. That's very hit-or-miss. Ears are probably better.

$10 DVMs can and do have AC measurement features. There is no reason
why they can't be accurate enough to outdo ears, which are not very
accurate at all.

All of the $10 DVMs I've come across only have a high voltage AC range,
which is obtained by rectifying the incoming voltage and measuring the DC.
As such, it can't make decent measurements of low voltages.

It doesn't have to - level matching should be done at the speaker
terminals.
