Hey all, put 2 different 3.5 drivers in small home built cabinets. Voigt is so easy to build and modifiable. The driver and port are so far away it seems? To open up the sound stage alot. Real airy. I am sampling with a good 2 way monitor and at close field I always like the single driver Voight cabinet. Maybe prejudice but with out any xover or phase issues the drivers just give their all?

"The domestic corner horn" sure looks interesting - too bad they dont show the internal structure as with the rest. I have to wonder how a "2034" revamp on the idea would sound, with todays CAD / modeling advantages?
Maybe. Some think there's a critical range of frequencies that if covered by a single driver, is better than split between two. Your 3.5s are obviously sailing right through that, un-perturbed. What is it? Where your two-way probably crosses.
Voigt was an engineer in the 40s. YouTube had video explaining principle and a build project. "World's second best speaker" old concept but really amazing to get the most a driver has to offer without the usual take away from way. Very open and airy with VERY little cabinet resonance do to quarter or half wave cancelation effect. Something like that? Michael
Like any quarter wave line a Voigt should be properly modeled. And it has been shown that an ML-Voigt is much better than just a voigt.

IIRC the plans are (were?) on the net.
Not having the option to audition one all I can say is that ('FR', coax driver) compound horns, especially corner loaded ones were quite impressive to me and my then teen friends (some adults too, but presume they were just being supportive) based on some small, very simple TL POCs I did using heavy duty packing crate type cardboard and 'reclaimed' 8"? whizzer coax.
My SWAG though is that modern tools wouldn't so much as 'improve' the original as allow us to easily convert it to suit modern drivers, electronics and even then it would be very subjective since the pioneer's being forced to design speaker 'systems' optimized to the max thanks to Bell Labs' extensive research WRT human hearing perception such that when combined with variable DF tone controls can sound more 'life-like' overall to me than any modern technically superior electronically controlled/DSP'd (multiway) driver system that I've been exposed to.
Another nice corner horn is the University “Dean” and “Classic”. I have modeled this one in Akabak with modern drivers in another forum here:

My thoughts on back loaded horns is that I think they sound great. I don’t know of another way of bringing out the bass dynamics of single full range driver so nicely.
Of all BLH’s the Cornu is by far the easiest (in foam core) and most compact to make and it sounds super impressive.

I will look into the ML-Voigt next build. Try and follow plans. Will use Dayton PS driver smallest one as already have. Top and bottom end are impressive. Way better than B3N Hi Vi. Thanks looking up plans next. Probably will reduce size to use with this little driver Michael
How do you describe the sound character? Horns I've heard really sound really natural. Even like horn loaded tweeters. Especially metal that get a bad reputation for break up but usually happens very high up past ,,30,KHz. Soft domes break up earlier but more subtilty. That plan looks fairly difficult to make.Another nice corner horn is the University “Dean” and “Classic”. I have modeled this one in Akabak with modern drivers in another forum here:

A BLH, typically will sound quite warm and natural but will not be as flat in frequency response as TL. The bass may have more peaks and dips.
As far as easy, make the foam core Cornu of you want a quick project that’s not expensive.

Another easy ML-TL but could almost be a horn is the Karlsonator. That also sounds very nice and is easy to build in foamcore.
Hundreds of people have built these and everyone says they sound great. Lively and warm and very engaging experience but not flat measuring by any means. I listen to them everyday as kitchen speakers for general music playing.

That's encouraging, as it corresponds to the original perception, at least according to what I read. My curiosity is around a FLH using an ordinary driver, vs a CD. When I look at some of the synergy stuff, the cone speakers sometimes are compression loaded too - with a large diameter squish area and relatively small exit port. I'm sure the pointing up with bank shot arrangement could be done as a synergy - what a "trip" that would be - but a single driver (considering the SPLs I listen to, vs live performance duty) would be so much easier. Anyway, they'd both be fun to hear, as I've never heard anything like 'em! Maybe an interesting way would be a stack of foamular, each panel cut to a shape so the sound bounces off the stack edges. /Dreamer_Mode...

This reminds me of the Edgar Show Horn..

Any plans for horn loaded design that isn't so had to build. I don't follow exact dimensions just ry and get it close especially volume. Michael
my daughter and I built folded Voigt pipes for her dorm room when she went away for college. very simple to figure out and here is a good thread to start with but look them up on Google and you will find many more.

Try the BIB. It’s a folded back loaded horn. Easy to design with spreadsheet calculator. Huge thread on it. Very easy to build.
You familiar with AER Goldie DML acrylic design? Am giving acrylic panels a try using YouTube hybrid DML 4 part build. Extremely cheap and easy quick build. What is your opinion on these type of speakers? Respect your advice. Michael
