Okay, before watching this, please acknowledge that it was "filmed" with an old iPhone so there are extreme limitations in the audio reproduction. The only real point here is to get a slight sense of how well these little speakers can handle music (and SPLs) that they were probably never intended for. In-room, the midrange and highs are far, far better than in the video. Still, look at those little 4 inchers crank out the bass. It sounds slightly more representative near the end of the video as I get closer to the left speaker. Flamers will be ignored. The amp is my TPA3118D2 "Weiner" (sitting on top of my Tubelab SSE).
This is WAY louder than I would normally listen (95-101-ish dB peaks). Again, just an extreme demo. I'll post another video of how I would more typically use these speakers.

A more typical demo. The sound quality is still severely limited, but anyway. Grain of salt and all that. Driven by my Tubelab SSE, which is pushing maybe 6 watts or so here.

To relate this back to the earlier discussion - I tried similar "tests" with my Pensil 10.2 and the driver cones were flapping around like mad and the bass was a mess. I'm reckless that way. They were never designed for it. Actually put a couple of wrinkles in one of the cones.
So maybe this is an example of what not to do with your full range drivers. All I can say is that the EL70 takes anything I've thrown at it. They can easily pound out more, tighter bass than the Pensil 10.2 could, all day.

Thanks Jeff 🙂
By the way, no tone controls or equalization involved here. FLAC ("bit perfect") --> DAC --> Pre --> Amp --> Speakers.

Odd question; is the back door on the super pensil necessary? It appears the others do not have one.
No. It is there to make it possible to easily adjust the damping — seems that many do. It is not required but i would not leave it out unless you can reach thru the driver hole to near the bottom of the box (ie long arms, bug driver).

Haha, I’m not that limber.
Wouldn’t the bracing and rear door produce resonance? I guess you could bolt the door to the brace.

Yes, the back should be screwed to the brace. The brace pushed resonances up and distributes driver reactive force to 4 panels instead of it all loading into the baffle.
Whether gluing it reduces potential resonances improves things would have to be evaluated in the field with one with and one without.
