That was me.

The original drivers in these speakers were about that size (92mm outer frame diameter). I was thinking about something that would beat those really expensive Bose computer speakers. There are some Tang Band speaker modules that might do it, but I don't feel like paying that much (close to $70 for a pair).

Given the small cabinet sizes of these woofers, they have the typical double-humped response, with one peak in the 40-55 Hz range, and the other in the 100-120 Hz range. Their bass response also drops off very sharply below 40-50 Hz, depending on design.
So yeah, they do often have a boomy midbass, or at least very exaggerated low-end on voice content.
The really cheap ones have a simple ported enclosure with what looks like a toilet paper tube as a port. One example that I have personally listened to is the Cyber Acoustics CA-3602. On those, turning up the bass control just makes speech impossible to understand, and the bass response drops off at about the same frequency range as the old Dell / Harman Kardon 2.0 speakers like the HK-206.

I suppose if you don't mind sacrificing a small DC motor, you can probably get some from there... or scrapped CRT TVs possibly (yoke and focus/pin coils.)
I didn't spend much time looking for wire, but I don't think I have anything in my scrap pile with thin enough wire.

These are cheap, but resonance is less of a problem with the new drivers. Putting damping material in modern $10 speakers would be even more pointless, although the set I have sounds better with the speakers in free air than with the speakers inside the enclosure.
