Newb question about testing old speakers

I have 3 sets of old Duntech PCL-3 speakers (on wall and amazing).  I high suspect that, given their age and getting them from different places, the crossovers differ greatly in each speaker.  So where should I start? How so I measure?

 

I would like to bring them all up to date.  They all "sound great" but I would like evidence other than my ears that they're up to snuff.

 

I have a mutlimeter but need to be told how to use it and what to look for.

@fiesta75 what do you mean they have an active crossover? I'm not an xover expert but what would make them active?  I thought they were passive.

The crossover is located before the output of the amplifier. It divides the low and high frequencies at the input of each amplifier, so the drivers are driven more efficiently. From GPT: An active speaker crossover is an electronic circuit that splits an audio signal into different frequency ranges before amplification, sending lows, mids, and highs to separate amplifiers and speaker drivers. This ensures each driver (woofer, midrange, tweeter) only receives the frequencies it is designed to reproduce, improving clarity, efficiency, and reducing distortion

** To All: Apparently, I am mistaken, the stock Duntech PCL-3 DO NOT have an active crossover. I'm sorry for the error and confusion!
