Making speakers sound tonally similar with an equalizer

Make no mistake about it, the fun you can have with a $300 Schitt Lokius slightly modifying/shaping the sound of your speakers a no brainer.  No, of course it won’t change the sound of one speaker to sound like another.

While I say EQ's are a bad way to try to make one speaker sound like another, I've also seen Stereophile adopt B&W speakers as their reference, and Golden Ear matched it and got rave reviews... so... maybe there's something to it.

I’ve owned many speakers and they all sound different. I would say very difficult or impossible. Maybe if the speakers are in the same line- cabinet materials, driver materials, crossover components, etc. otherwise too many variables. I suppose frequency is frequency so there is an argument for it, but I say no way.

You might have better luck with a Realiser A16 and headphones trying to replicate certain speakers.

IMO no you can bandaid but can’t replicate something better. I had the Lyngdorf 2170 and it made Tekton Double Impacts sound amazing when room correction engaged. The difference with some other speakers was actually worse than natural. So dunno. My guess is efficient speakers are much easier to voice with EQ or room correction.
