The OP doesn't want a modern design or an optimum one but a sealed full range one although he doesn't say why. Such speakers are going to be few and far between given the cone area required to get satisfactory SPLs down to 20 Hz and the use of distributed subs to get high quality low frequency performance in rooms. SP Acoustics make large sealed monitors for "professional" use but, inevitably, there is an audiophile tax given the target audience. The best are likely to be something like the Beolab 90s but, given the Zaph SB12.3 example, I think the OP maybe looking for something cheaper. The Devialet Phantom can be setup for surround sound and is a better price but may or may not be an option depending on what is leading to the requirements for sealed and full range.
The D&D seems to be appreciated in recording land. I can see why. And it meets the spec I guess. Closed and full-range (certainly for piano recording, the lowest octave isn’t very popular in piano pieces as far as I know).
The D&D is not closed/sealed. It has a venting arrangement to passively create an approximate cardioid radiation pattern. Good stuff but not sealed.
Like we would not know. But it’s the midrange that has an ‘open’ back. The woofers are sealed.
Now, what we don’t know is what has to be sealed (the tweeter of the D&D is, too) or why it has to be sealed, we just have to assume here. I assume someone is looking for a monitor for recording/producing piano recordings.

I believe the op was saying full range 20hz-20Khz reproduction with a sealed system, maybe not a standalone full range driver in a sealed enclosure...?
Must be this one then.

Must put a 15" below (or above), and put the 3" naked with felt cover behind.
10 mH coil and 100 uF for a start.

For 'sealed' One might think many things.
One of its meanings Is to Seal the sound, so the box Is sound proof and the speaker Is the only emission. Rarely It happens, and that's strange 'cos it's the basic function of a box
Now...what I've suggested before conflicts with that rule, but midrange Is different than bass. Indeed, in reality a 15" at home Is stra-gigantic, go figure...
Talking about boxes, assuming that they absorb back waves, there Is the membrane, in case the of a woofer- the only speaker that needs a 'box'- which Is required to vibrate from 20 Hz and up- 17 m long wave and diminishing...- It might suggest that a sealed box has no meaning in a... dynamic status analysis.

Regarding OP's question, he/She asks for state of the art loudspeakers, I mean the best you could get if you had the Money..and time...and space... Big houses...state-of-the-art walls and dimensions of the listening room... because you Need a listening room for keeping all your state-of-the-art devices for reproducing music!
Why is sealed a requirement?
Its like saying "it must have a V8" - that's an emotional requirement, not a performance requirement.

Sealed produces very low group delay for “tight bass”. A properly designed tapered TL (a la PMC) can also do this.
If we are looking at 8in woofers and DIY designs, my 10F/RS225 FAST in sealed 24L box certainly qualifies and sounds super based on peer reviews. Many happy builds in DIYA land.

Of all the speakers I have the one I like best is a Fane 12-250WRMS full ranger.
I have a pair in a sealed box and I am pleased with the sound and efficiency.

"Full range" in the OP question is about multi-way spaker with sufficiently wide frequency response (close to 20Hz - 20kHz) for studio use, not about a single fullrange driver.
The OP appears not to understand the purpose of this forum, nor its long running terminology. That makes for a troubled thread.
Fortunately for the OP there are plenty of audio forums dedicated to this sort of question.
