I tried something else last night, I turned on my subwoofer for the first time in 3 years. I set the cardboard mets to small, set the crossover to 200hz, and gave it a try. They have much more of a low end of course, but overall I didn't really care for the effect. With the xover setting so high the sound becomes directional so I could hear it from one side where the sub is. I never really liked the sound of the sub anyway. It is an older SVS.
On occasion I have epxressed my dislike for a foam surround . Some time ago I obtained three FE127e's and I applied the pre-treatment and then put these in the folded monopole. Big difference with the FF105WK and FF125WK metronomes. In the end I no longer could stand the monopoles and shortened the port on the FF125WK metronome to 2" and put the FE127e in there - MJK worksheets indicate it is not optimal but I like it a lot more than the folded monopoles - the bass is more noticeable than with the FF125WK but not unpleasant. (but not going as deep...).

I've had the Mets w/ subwoofer plugged in for a week now and after a few tweaks on the settings, mostly lowering the output of the sub, and a little break in of the ears (beyond softening of the surrounds and other moving parts, I don't believe in break in, it is mostly becoming accustomed to a sound IMHO), I hit a sweet spot. These are so nice sounding that I never want to turn them off.
My son came home from school tonight and he walked in and asked "what did you do to your system? That just sounds soooo good". When I explained the $5 drivers in cardboard he just wanted a pair. Then I mentioned the sub and he realized it was an illusion, but that doesn't take away from how nice this now sounds.
So now I still have to take it all apart so I can measure the drivers and build something else with them so they can stand alone without the sub.

Height will be similar to the FF85k met we modeled a long time ago... 12" internal.

No, I don't have access to your email.
A 12" metronome would be cute. Can't be much bass though.
I'm liking this. 
Big pipe for the little 'un. Damped out to taste, nice EBS style alignment with a bit of a flick at 50Hz to give a bit more presence. Vent velocity (forgot to add that one, apologies) would normally be a little high for my taste, but being downward firing, unlikely to be an issue here. Impedance pretty unreactive -similar to what I do with some of my over-sized MLTL alignments, but with a much lower damping density. Pretty well controlled excursion too. For these, I assumed all faces lined to a couple of inches below the driver, then back & one sidewall to the bottom. Nice job (as always) Greg!

Thanks!
Hmm, the vent is bigger than Small's formula based on Sd, Xmax, Fb for an inaudibly low vent mach, so curious why it would sim a bit high.
Regardless, the HR sim shows no under-damped Fb and a ~62 Hz excursion minima, so curious how it looks with modest stuffing all the down and increasing Dv to 2.54 cm or whatever is required to get the dip up to ~62 Hz.
TIA,
