I guess you could remove the cap, pull out the spout and use them as " adjustable, directional" ports.Think I've seen everything and then these? Are they 'acoustic suspension' or ported? i.e. removing the cap fill becomes ported? or open just a little?

Did you include any acoustic padding behind the speakers to possibly prevent any "boxy" type sound?
Drilling several small holes in the back, then covering them (inside) with padding helps too!
Found this pic on Facebook and reposted it here for laughs.
Nice work!
Just a thought, if you burn a voice coil while testing, in the presence of gas fumes, how far will the cone travel across the room?

Hope your amp doesn't run out of gas trying to drive them.
