Today... you can get all three. Lot of new speakers now can do it all.

The JBL M2 is one which covers all the bases very well. But, also several 2 way near-field 'monitor' speakers can do it. Dont forget DSP is an available tool also.

Other tools like DEQX are also available. Home - DEQX

As Richard said, with active filters using DSPs, we can do whatever we want: Slope and Q of the filters, response curve correction with multiple EQ, time delays. etc.
DEQX or Behringer.

If you are happy with DSP correction, then I am all for you. I know that Richard depends on digital correction, however I don't. I really don't like digital that well. Perhaps someday. Yet, I don't think that most people have a good idea about their individual speaker system and its tradeoffs. That is what I prefer to talk about.

UREI was making time alined horn speaker with analog filter in 70's, and JBL did in 80's, so it is not impossible, but I have to agree that those are a few exceptions.

John, I thing I understand the reason why you "don't like digital that well". ;-)
A feeling that something is lost or missing in the signal.
But, if, one day, you have the opportunity to compare (blind if possible) an original analog master to its vinyl copy, an analog tape copy and a (good) digital copy, you will definitively change your mind ;-)
...And begin to dedicate all your attention to the analog part that follows the DACs.

Of course. The only real problem is the Woman Acceptance Factor, if you try to time align low medium horns with bass speakers in an enclosure
that you draw for domestic living rooms ;-)
