IKEA launches modular speaker line - watch out Wilson, Magico...

How about listening to them for one's self, after all, you are the end user.
If the kef speakers had perfect measurements, does that mean you would like them. Or, you being a specs. guy, do excellent specs., mean you must like them?

The kef sounded horrible and was several thousand dollars.

And, that is your opinion only, not a fact.
