2-way systems with smaller horns like this and 15" bass nearly always exhibit a large response dip near the crossover frequency. That can work well for some types of rock, but it's deficient for nearly everything else.

Ridiculous over en-composing statement.
Not perfect but no dip at my xover at 1500hz. There's enough efficiency that some adjustments can be accomplished in the network.

There's no dip, but that's on axis. Off-axis there will be with a fifteen crossed that high. Off-axis response is the issue with large drivers crossed over too high, not axial response.
It's difficult to interpret a graph with no legend, especially when the Y axis is zero everywhere. Are you really crossing a 15" woofer at 1.5kHz? Sorry, that's not hi-fi.

So all the later Altec 604 are junk?

Allong with Tannoy DC's, an many others.
I guess I'm glad I'm not high-fi... it seems exhausting.
No dip that I can hear. See frequency response graph below. Millions of pro audio and studio monitors can't be wrong.

I don't see a graph in your post. That aside, what we're discussing is a fundamental concept. The laws of physics haven't being changed to our benefit just because a manufacturer slaps a logo on a deficient design. Pushing a 15" woofer into the middle of the vocal range is musical ruination.

Have you tried an aperture plate in front of the woofer?
Does that provide some compression loading or is there another effect?
No, it's just a diffraction slot (basic physics).
There was an article in the JAES many years ago, it's in the first speaker anthology.
