You are welcome.
Super Chorus inspired project.
My cat Magneto says, " I don't banter often, but when I do, it's about unspayed female cats running around outside my screened in porch".
Just an observation, and opinion, not a requirement by y'all. It would be boring otherwise, aye? I had to shake you guys up a bit anyhow. LOL.
Besides, the name was my original suggestion to Gigantic anyhow. So the active additions are what have strayed from a Klipsch Passsive Network mod.

Only because you really didn’t like it when I called it a “Chornscala” last fall. 
Admittedly, it’s a really dumb name that I used in jest.
At any rate, after I reconfigured the networks on bigger boards, I’d begun to have an inkling that I’d painted/tuned myself into a corner, perhaps before that. It sounded quite good, but I’d lost a reference for how it should have sounded; it seemed veiled, less clear or less open, as if the sound stage was compressed and the tweeter less present. I was inclined to write it off to my hearing getting marginally worse, playing test tones, the speakers began to run out of steam below what was my last tested hearing threshold. Thanks to Mike’s troubleshooting, I’ve got it wired correctly and all of the clarity it had previously is back and then some. The DSP has been a boon as well, giving me a better glimpse of how the final product might sound. Next week, I’ll order the Baltic Birch (actually Spartan Ply) and we’ll get started on the new speakers. It’s a far cry from how I’d imagined it might sound when I decided to restore the 1971 H700’s I kept tripping over in my carriage house last July.

My bad, I should have said all y'all. I spent enough time in the South to qualify. I could never be a Vermonter, but, I'm a Quebecois, which is way north, so you are all southwesterners to me.

I had been costing this out and I'd wanted it to have a 5/4" solid hardwood baffle with either beveled or rounded edges, glued and screwed atop the BB ply motorboard and top. It turned out that even the least expensive options would have cost me an additional $500-$700, which has given me some pause. After some gentle, good-natured haranguing from @THD+N and @Invidiosulus, I think I'll go a vented La Scala clone instead, with the 18" X 10" mid and @Daveintn's L-MAHL and rear mounted vents in the horn housing. I just have to work on the WAF, my S/F was a little supercilious when I showed her a photo of them, but hopefully, we'll get out to one of the listening rooms in our neighborhood and the proof will be in the pudding. With the bigger mid and squawker horns, we'll have a larger enclosure that should offset the horn displacement and give deeper extension than a bin below the bottom, as well as not contribute excessively to the overall cabinet size. So, I'll let this thread die on the vine and start a new thread when I begin the LS project- I've already downloaded plans complete with cut sheets and I'll begin ordering the ply this week.
LaScalas are good looking speakers, even in RAW Birch (the Triangle thing). But it cracks me (out loud) up to see you worry about this hobby's relative "chump change" when building speakers that, commercially produced, would be worth at least $5,000-10,000 a pair in Quality Sound. Not a bad choice since you have learned so much in such a short time, but I fail to empathise with the material cost thing. My problem, not yours. Don't forget to brace the walls.

I’m a working class slob and grad-school dropout with more student loan debt than I can ever dream of repaying. I’m funding my audio hobby with a side hustle building and painting guitars, with the intent than aside from a slush fund that covers buying records, none of it is paid for out of my wages. While I’d love to be able to casually buy underground jubilees, khorns, 402 horns and have multiple projects going on at once, I’m left to make the most of a modest middle class income.

Your dilemma reminds me of my "main" hobby of making beer. We warn the newcomers to the hobby that you will never "save" money by making your own beer since you will be upgrading and expanding your equipment.

My other hobbies include motorcycles (I’m a former motorcycle road racer and trackday instructor, and cycling, I currently am down to just one motorcycle, but I have 5 bicycles. I also have around twenty guitars and a small recording studio in my spare bedroom. I don’t do cheap hobbies, even though I’m a cheap bastard.
You guys have not idea how poor I really was after the big crash of 2008 and subsequent divorce (and still am). But my kids were all grown so party time for Dad with used gear.. Otherwise you would understand why I laugh at your "budgetary" comments. Gigantic, I'm thinking of selling speakers so I can buy guitars. LOL.

I was working in construction during the 2008 crash. I went from doing $250K kitchen remodels to $125k whole house projects. Since I'd spent almost the entirety of my career doing very high end work that had to be perfect no matter the cost, I couldn't get my head around doing work that was "good enough," and I nearly lost my shirt on a few occasions. by 2010, I'd utterly destroyed my knees and was forced to retire at the ripe age of 40. I became a freelance moto-journalist and from 2010-2018, averaged between $8k-$30k a year. I also had medical issues during that period, was forced into bankruptcy and lost nearly everything I owned. At one point around 2013, I owned just 2 suitcases of clothing, a bicycle, my laptop, a camera, a rug, a blanket and a pillow. I slept on a friend's floor for 6 months.
at any rate, I will be building better speakers for less money. I recall someone saying, "A bigger horn is a better horn," La Scala > Chorus, no?

Well I have had a boat load of La Scalas and a fair number of Chorus 1's 2's and KP-301's. For all around versatile music appreciation you cant beat the Chorus type cabinet. That La Scala can get really loud but no bass to speak of. My preference would be for a Chorus type without question. Cheaper and easier to build, much wider range of hz and smaller footprint for those who have space problems. I built a set of La Scalas using 25mm Baltic Birch with the side walls 2" deeper so that dog house point was not getting beaten up. Then made it a two piece with the top hat cut so I could use an LMAHL in there and a recapped AA crossover with no zeners. It was a very nice set but still did not touch those Chorus 1's for fidelity and more accurate deeper note playback. Recap that crossover and stick an LMAHL in there and enjoy for the next 20 years. I have plans for 301's and Chorus speakers if you need them I believe.
Dave makes a good point or two, but it's hard to beat MIDBASS HORN definition and lower distortion. PWK used H, then Corn, then Belle (pretty LS) as MONO center channel in his original development room (museum) and his home with 25" spacing (to fill the Hole in the Middle) Why? because DISTORTION from a Direct Radiator is 15 db higher than a horn, creating sidebands that don't exist in the original music.
So if you do the DJK/THD+N thing and build Ported LaScala, then you have the opportunity to use a higher BL woofer, and a bigger top (optimized air volume) in which to put rear ports, bigger Mid Horns, LMAHLs, and Crossover. You can call it whatever you want. So plan, simulate and measure if that's what you build.
I just wanna know what BOAT you put all that stuff in so I can book a Vacation on it!
