Making speakers sound tonally similar with an equalizer

Don’t know,  but a 4 band EQ has been a Godsend for me since my hearing is deteriorating.  

Speakers can have very different sound "signatures" e,g,

• some might sound natural
• some might sound "boxy"
• some might sound "dull"
• some sound "lively"

That type of difference cannot be rectified with an equalizer

If one speaker is brighter sounding, you might be able to correct for that with an equalizer - that’s about it.

There are even different sound signatures even between models within a product line from the same manufacturer.

In fact, I cannot even remember liking all models from a single manufacturer to date.

The closest I have come to liking most speakers in a product line is Tannoy

OK. Figured there would be some unique sound signatures that cannot be duplicated easily and I presume is mostly sound emanating from the enclosure, construction, etc.
