If they have the same radiation characteristics and you are using a digital equalizer then yes, you can make them sound very similar.
Making speakers sound tonally similar with an equalizer
Can two different speakers be made to sound similar by adjusting their frequency response to mirror each other with an equalizer? I'm sure it's not as simple as that but would it be possible.
Can one, for example, reproduce a harbeth like sound by doing that?
Just curious.
