good morning to Everyone 🙂
A while ago I bought on ebay a pair of old ITT midrange domes that I had read a lot of good things about
Last week I received a Dayton Audio DATS V3 that i am currently using (great little unit by the way I love it )
To my great sadness, measuring the two drivers I see that the fs but also the impedance curves are quite different
Since they are aesthetically identical and with same part number I believe that the reason could be a degradation of the suspensions in particular
Needless to say that they are quite out of specs The original fs should have been quite lower
In a word they are mismatched
With the aim of selecting pairs of drivers with identical performances I wondered if a measurement of the impedance curve and the TS parameters is sufficient to establish that we have a matched pair
If not, what other type of measurements should be done?
I'm sad but i hope to to learn from my mistakes
Thanks everyone and have a good day

Hi i add another question for those using DATS
is it possible to compare two impedance curves and maybe to get the differences automatically ?
or to check the TS parameters should be enough ?
as i said above a friend of mine has a huge collection of drivers that he would like to check and possibly match
I would love to be a little help for my friend

Maybe approach the testing from a different angle:
A measurement microphone and REW software.
Mount speakers on a beffle and place mic 1m on axis and then measure.
Amazon sell suitable mics (eg Daytona) and a Behringer UAC222 audio interface. Of course you'll need a power amp to drive them.

Hi thank you very much for your kind and valuable reply Therefore what really characterizes a driver in the end is its frequency response
i think i have already a cheap Behringer mic somewhere that should work
I have a question Rew software can compare two different frequency sweeps for differences ?
i am obsessed about having two speakers quite identical First rule in stereo is to treat the signal L and R in the same way

Thanks again I finally have a direction
In order to avoid reflections from walls i have seen someone using blankets
My main goal is to have identical speakers Or drivers
better two equally bad than one bad and one good
