Here's my system, a systems approach

I have a few that listened to it that want to duplicate it. I feel that the key is having two ten inch low mids assigned to 100-900hz where most of the music spectrum is presented, vs one small mid.

There are some weird effects there. If mouse is on the browser window you have grey text on a grey background. I get from your equipment you like grey 
. If you move the mouse out the browser window its still grey on grey but almost legible.
BTW what's a 'Butwrt'? Sounds painful, hope you can get ointment for it!

Yes, the cut and paste from a Word file resulted in the strange colors. You can read it If you hover or drag your mouse over the text. "Butwrt" yes, like Mrs Butterworth.
My 3 way speakers, started off as active with using a minidsp. Ended up
changing them to passive set-up recently.
Speakers were made by stacking CNC'd plywood layers, bass section has wall cavity mass loaded with lead.
Midrange/Tweeter baffle and insert made from aluminium, insert was to allow SS ring radiator to be changed
to Ribbon.
Crossover points, 350Hz & 2800Hz
Drivers:
Scanspeak Ring Radiator
AudioTechnology 18H mid
AudioTechnology 2 x 10A Woofer made to suit sealed enclosure.

Nice speakers! For the passive crossover, did you build using the same parameters you had programmed for MiniDSP, or you came along with a new setup?
I only used the same crossover points l ended up with in the Minidsp, l prefer the passive version over the active, the sealed bass from 4 x 10’s is pretty impressive even without any low end boosting done when it was active.
The $$$$ question is, what is your amplifier. Because some good amplifiers can drive speaker as if nothing is in between (the passive crossover is inaudible).
Good...I am changing from active to passive on my DIY 2-Way bookshelfs. Doing the same, using the parameters (XO points and gain adjustment-LPad) I had in the active.
two way bass reflex
This is my first speaker .
For the calculus i have used an old paper by
Patrick j. Snyder n°1307
I have implied a low cost 8" woofer for P.A. and a tweeter
vifa from my old two way esb cdx .
The case is double layer and the sensitivity is about 90dBspl.
The cross-over is made using the Allen.B guide and have a first order for each way
(thanks Alllen.B) .

sound ...
The principal aspect of the sound is the stability of the scene this is made by an a half
first order cut off over tweeter and woofer cells .
The case don't have a audible resonances and the behaviour in frequency is next to the
closed box to increase the velocity response .
At start i was undecided among a single way TL and a bass reflex two way.

I remember Pat Snyder from SpeakerLab here in Seattle. A very bright guy and quite interesting to listen to!
