Will the 3/4" dome tweeters be able to provide enough SPL at the low end of their passband?

Surely not an issue for either 6 or 4kHz?

The tweeter is capable of max power of 40 watts which translates to 113 dB/M. There should not be any problems with the crossover at 4k or higher, 4th other or higher.

To answer the question about where I am headed. I am continuing to refine my dipole speaker designs by achieving better control of directivity and also trying to make the speaker as economical as possible for the DIY community. Music and Design is a for the love of it venture.

That's a crazy looking baffle SL has there!
Looks like a Vase or a lantern.

why do people care so much for flat sound ?

I had a buddy who made and sold speakers for a store (early 80's).

People always bought his speaker that had the midrange shelved down by a few db over the same components that masured flat.

I don't understand compensating for the Fletcher–Munson curve when eq'ing loudspeakers, we can't tailor sounds in real life to compensate for the curve.
Sound pressure should be the same for all frequencies in loudspeakers to mirror real life? No?

Maybe a little boost on the top end, to counteract HF loss in a furnished room.
But then again, a downward slope at HF would sound more natural because it adds perceived distance from the source.

Speakers with "built-in" HRTF-like distortions theoretically work but the problem here is that HRTFs are not the same for each and every person. Furthermore room interaction will interfere with the speaker's HRTF-distortions in unforeseeable ways. Not a good approach in speaker design.

Let's assume for a moment that the recording engineer mixes the recording using flat monitors. Then why would there be any need to correct for HRTFs or anything else for that matter. It should be "build in" to the recording. Cutting, boosting or any deviation from the response of the monitor is simply saying 1) the recording engineer got it wrong, 2) the speakers being used for play back are significantly different from those used for monitoring, 3) the listening environment is significantly different that that used for monitoring, 4) personal preferences are different.

This is why I design for flat response. I don't claim it to be correct for everyone's room, recording, or preferences, but it provides a standard reference from which the listener can make his own adjustments using the controls I build into the speaker/crossover. And with this new Note using a dsp crossover the listener has great freedom to tune the system to his environment and taste.

I also feel that when I design a speaker I need a fixed reference. For example, how would I be able to evaluate the difference between the Note and the NaO II which could be attributed to polar response if the two system had different axial response?

And as I said when this was discussed before, if there is a need to correct for HRTFs then it should be done in the recording, not the speakers. And if not the recording, perhaps somewhere else in the play back chain; the CD player, a change in the RIAA phono curve, the preamp, the power amp... It just doesn't make sense that every recording engineer got it wrong on every recording.

Amen but you also have to admit that a CD speaker from top to bottom is not what is used in mixing/mastering.
