Neat that this circle just opened up, because it makes it easy for me to ask a question I had looking around the Spatial website.
I know this might be a little out there, but could the M3TM be built on the base/frame of the X1? I watched the build videos (I think of the M4?) that showed some of the CNC machining for each of the baffle layers, and it looks like the cutouts for the wire routing wouldn't get in the way of the mounting points of the X1 frame.
Also, I thought it would be an easy way to get the M3 tweeter up to ear height without messing with the baffle much, as well as get it to 90 degrees from the floor (am I remembering correctly that there is a bit of a tilt to the M3 as currently built to account for the reduced tweeter height?). I'm thinking these two things together might be worthwhile/advantageous with the new open backed tweeter to better position the backwave radiation pattern for the compression driver?
I'm sure potential shipping costs would increase, as I'm guessing the X1 bases can't flat-pack as well as the M3 hardware, but the idea does use all (Spatial) off the shelf parts, so maybe not as insurmountable a cost difference from engineering unique parts from scratch?
Lastly, I really like the look of the X1, and I would presume the added stability from the heavier frame might be advantageous in certain in-home situations (say, heavy pile carpet?), not to mention more firmly planting the driver baffle to the ground?
So, am I crazy or could an M3TM-X be a thing?
