I have data for the MAC-05 and am currently using it in a small 2-way that I took to InDIYana in April and CSS Detroit a few weeks ago. I'll send you a message regarding data and other details.
It's less tall 😎 The squat shape usually makes it easier to get tweeter and mirange at ear height when on a mixing console/desk (usually elevated vs your bum). If you don't have this advantage on your desk area, then normal vertical alignment is fine.
Oh, I know this one is probably outside your budget but it's a neat way to save on height and get very good close distance of tweeter to mid dome:

Do they use Sigma Studio?
Do you need one for each channel? Or does one board have 6 outputs?
The only way I could do side by side is if I placed them above my monitors (there are 3) and pointed them downwards. I feel like this is a bad idea
I have looked at those Morels sooooooo many times.
@Bmsluite, here's my near field listening little auditorium...
View from the listening position. Distance is circa 2.50m :
The listening position sofa is at the lower right below (you see its armrest) :
Below with larger 4-ways added :
So as you can see above, using quite large speakers is not a problem, if you ever think about it... Smaller speakers are also fine too :
This is the magic of the near-field listening, with one limit though : the loudness, which must stay moderate to medium, you guessed it.

The better smaller full ranges?…….yes. The issue they suffer from is poor off axis response higher in frequency so they’re really only suited for either near field listening or a well treated room. Next is asking them to play midbass…..the moving cone sucks the resolution out of three high frequency…..add a support woofer and things get better….much better.
Yes.
One board has three amplification channels, each channel has its own power PWM DAC 100W at 4 Ohm, and one DSP that feeds data to these three power DACs. The power DAC has local feedback on the PWM signal, which achieves a low level of noise and distortion compared to similar solutions.
For stereo, you will need two such boards. I want to draw your attention to the fact that the analog signal is present only at the output of the PWM DAC, this module has no problems with background and everything related to low-signal analog signals.
In the first post of this topic, a structural diagram of this board is drawn. Below are examples of projects for this board in Sigma Studio.

My living room is about this size. According to this, all of my lsitneing is near field.@Bmsluite, here's my near field listening little auditorium...

I consider near field less than 3 feet between drivers and your head
I tried wrapping my last build in alcantara for this reason. Well, and for looks. It did not go as planned. It was to hard too cut cleanly
How about small speakers with slam!

Retsel,
I have those in my shop pool room already. They are incredible. I have them in a box with two 8" ports and they do slam.
What's with the curved plate in from of them?

Excellent Idea actually! 3 way is perfect for nearfield. I used a Pioneer 3 way ( large but worked) and a Altec 3 way ( soft dome tweet, was marvelous)
On my desktop for music and video editing for years.
Thinking now it is exactly what I want on my desk is a small dome mid, combined with very close small tweeter.
I always had 12" or 8" woofers in the past. So this time will be modern 7" woofer for bass vs size balance.
I have used under desk " subs" but refuse to deal with that nonsense now.
Decided on a fabric dome tweet from Dayton as well, and actually this thread inspired me to finally finish the crossover design last night.
Will do a full thread soon. But just a quick peek at some early design concepts for the fabric dome setup.
IIRC, I read somewhere (but where ?) that the limit of near-field and far-field distance could be 3x the largest dimension of the loudspeaker enclosure...
But here in France, we usually consider that when you are located at less than 3 meters of your enclosures, you are entering in the near field.

There is the room nearfield, the cabinet nearfield, the crossover integration nearfield, the driver nearfield etc, etc.. These things are different, and can be defined and measured.
Awesome, this is similar to what I'm leaning towards.
How did that Dayton fabric measure out? That is the one at the the top of my list right now.
I'm either going to do a dome mid 3 way orrrrr.... I'm going to try to figure how to implement the GRS 8" mid planar. That will be a challenge but it entirely doable.
Allen,
I had not heard of any of those differences until now. I will have to educate myself. I suppose I've been using the term "nearfield" this entire time

At my desk is less than a meter sbf my living room the distance between my ears and the drivers are around 2600mm
