WOW
Who's pile of goods is that!!

That's a friend's dungeon. He's a "Hornie."
Turned out I didn't have any Barons in mine, but he had several pair.
For my purposes, testing two-way with horns, these Viscounts I found there are better.
If these work, I'll try some Barons with asymmetric waveguides, like stage monitors, to overcome the limitations of their "lowboy" configuration.
The front baffles are removeable, so just about any driver combination can be installed in them using a custom baffle, as required. The box frames on these are lock-mitred, so they're quite stable with both front and back removed.
It'll take some extra effort to achieve a tight seal on the front, tho; it was not so critical an issue in the original ported design. I haven't worked that part out yet....
Here try this

Thanks, Rob.
The problem is sealing through the grille cloth, which wraps around the edge of the front baffle.
That foam tape may well work, since it "squashes" conformally....
Zilch,
I have found closed box systems to much more tolerant of tuning. Even if you are off 10 hz one direction or another the resultant product will sound pretty much similiar.
Vented boxes require much more precision to meet the end goal requirements.
Just my 2 cents worth for what its worth!

It's clear what happens as we increase the closed-box size with 123A from 1.6 cuft. L88 or L100 (green) to 2.0 cuft. L55 (blue) to 3.0 cuft. Baron (red) to 5.0 cuft. whatever (black).
Xmax is 7.874 mm., so 3.0, or 3.3 cuft., even, is likely "safe."
I think my L55 cabinets are ready for my 123A-1's!
The LE14H-1's will go into the 250 cabinets.
I only have to make one panel(front baffle) with cutout for the 12" and use a 800hz crossover to one of my Edgarhorns. I love the round tractix horns for their "non-hornlike" sound characteristic.
I will have to run a impedance curve on my WT2 for crossover design with the 123A-1.
I will also have to try out a 1st order crossover with a 20% frequency split at 1300hz also. (Just a hunch I have from a similiar experiment in the past).
With our buddy Giskard inactive lately, it is nice to see you and others taking the ball and running with it!

It's likely Giskard has tried this stuff before, like 2213H in closed EN3, for example.
I'm confident that if I suggest something REALLY stupid, he'll be so overcome with incensement as to reappear here for no other purpose than to kick my ass, in which case, as concomitant benefit, we'll get some good advice....
Giskard has tired of the grief by some of the members here and will likely just lurk around for the most part. I am fortunate that he still answers my e-mails.
And for those who question the DD66000 system, Giskard commented to me he did not turn on his own system for 2 weeks after hearing the Everest in person. That is testimonial enough for me!
