I kinda like 2nd order xover on these horns myself! You gotta try 2nd and 3rd order filters and see what they sound like and then you can decide.
I will tell you this, one time, when I had a BSS 366t in my system, I made a mistake programming my unit, and accidentally set the horns filters to to 1st order, 6db slopes! And I ran the system this way for a few days till I caught my mistake, BUT WOW, IT DID SOUND VERY VERY GOOD!
Something I am fond of is 2nd order Butterworth filters on my 15,s and horns, and 3rd order Butterworth on the tweeter.,

I figured that it was what was shown for the MA25 kit but the frame shown threw me off a bit.
10K max, eh.
Other than the inductors, I think I have enough to breadboard a 2nd order Butterworth for woofer and horn. I'll have to give the tweeter some more thought but certainly could go 3rd order on the tweeter for 3-way.
Where would you bring the tweeter in at if a guy were to go that route?
What I have on hand right now that isn't built into something would be a pair of E145's and Gauss 4583F's for woofers and a pair of Fostex T90A's or Yamaha JA4281B's for HF.
The bass cabs would probably end up being a not so pretty pair of Caberet that are close to the internal volume of the JBL 4507's.
With those cabs, it wouldn't end up being a "for show" set up but get me started anyway. My basement looks like a war zone anyway so they should fit in nicely with the decor in my audio area down there

Well it depends on the tweeter. Right now I am at 7k between the 2395/2441 and the 2404 bi-radial.
I am installing some brand new TAD ET-703 tweeters, they should arrive here next week. I, at the recommendation of others, including Mr. Widget whom I bought these from and he also uses them, will change to 8k when I install the 703,s!
So, depending on what tweeter you use.

Thanks guys! Great info. for me to work with now

The thread is 18 months old, but I think that I can contribute by presenting how to make the front stands and spending only a few bucks. That solution was inspired by Shorty on his DJ rig. The stands are 6" wide and 4.5" tall. I will sand them and paint them a dull black when I have time. The front stand are very sturdy.
That looks like a pretty slick way of handling it, Lee. If and when I get back to horsing around with mine, I'll steal that idea and run with it myself
So far, I built crossovers based in the of the suggestions presented and have played around with them running with 4507 cabs with E145's. If it goes any further, I will probably run them with my 4560's or build something.
I was messing around in Sketchup a while back and came up with this. Dim's are close but that wasn't the focus. I just wanted to get a visual representation of what was bouncing around in my melon

One thing that people forget is the "era" gear sounds and works best with "era" components. The iconic Klipshorn (forget the model) that sat in the corner is a prime example of a speaker that never delivered it's potential using the latest high powered Brystons and Crowns but, came to life with a 25 watt 70's tube amp.
That said, I found the rather horrid 2482 phenolic driver an excellent match with the large slate plate lens. Something about that combination just works. The lens seemed to tame that overly powered driver making it sound like a speaker-- smooth. One thing that I do remember about the 2395 lens is how wide and even the coverage was--double width VS height. You can't duplicate that with a cone driver. So my guess is it would work well in a house. I have never used the setup in such small confines but, loved the results when combined with an additional radial horn handling the long throw coverage for P.A. I also started off my career in the early 70's disco era using them at the Ramada Inn clubs...the only job I showed up early to, so I could play these systems for my own pleasure and indulgence.
I have fond memories of the 2395...they seem to get romanticized in my memory as I age-- a bygone era.
