Who wants to help build something like this?

[jack667]

I am not a speaker designer or engineer, just a curious designer who's been obsessed with horns for some time.

I've always been amazed there aren't many options when it comes to horn speakers - especially conical horn speakers. The only ones I can find from the likes of OMA or Avantgarde are tens of thousands of dollars.

I want to build something based around a JBL 2446 in a conical horn and a faital pro 12 or 15 woofer. I mocked up a really rough design of a speaker design I've struggled to find from an aesthetic point of view that I find pleasing. Of course this could be created in many different finishes.

Any takers?

(This is of course just for fun)

Oooo the image is stretched, click on it to see it un-stretched

- can't be of much help but admit its aesthetics are good and with proper crossover and appropriate amplifier, should make a fine 2 way system.

The discussion probably will be moved to "Multi-Way" where there will be more interaction and ideas

maybe pick a more contrasting background than white on white

Looks straightforward enough. Which bit would you like help with?

Since you posted this in full range forum, you could do this with something like an SB65WBAC25-4 in a Faital Pro LTH142 horn designed for 1.4in CD. It sounds really good - and cross over around 600Hz to 800Hz with a pro woofer of your choice. Leave off the synergy style woofer that I did here and you would have a similar system. Just not coaxial anymore. It would still sound great though. The compression drivers will have a hard time crossing that low, plus they just don’t sound as smooth as a fullrange.

I just realized that 3D-printing speaker horns could be a good idea. You could design a horn according to any mathematical formula and let the printer make few identical horns.

I guess I'm looking for someone to help build a prototype - like I said I have no experience building speakers - I'm a designer (interior ) by trade. 3D printing the horn sounds really interesting!

It's difficult to find horn speakers that look great and don't cost tens of thousands..

Any advice on finding

- Cabinet makers (East Coast)
- 3d printers
- Anything else I'm forgetting

I think these could be really awesome speakers!

Possibly nice in a wood finish also

Use a Faital Pro 15PR400 in a sealed box. Minidsp HD. 700 Hz.

A round-over for the horn to fight diffraction and you good to go.

buy yourself a cheap/mid range table saw and some ply& 2x2 before the next lock-down, it would help if you had a large shed/garage to work in. draw it out on paper first, before you start cutting. the boxes could be constructed in one solid days work.

jmlc horns by Auto-Tech in Poland get good reviews.

JMLC-350 – Horns by Auto-Tech

-----------
The eJMLC-300 has a wide vertical polar pattern at high frequencies.... and looks like a pair of hot-lips. The $400 coaxial BMS 4590 compression driver would complete a 400-20kHz design. Image... Big Red Lips on top of two side-side black 15" woofers

How about someone with a measurement mic to do some crossover design?
FWIW, my woodworking is probably good enough for a prototype, but I tend to stick with simple cabinet designs.

They could be, especially if you can develop both ends of the horn. It isn't a conical you are looking for, but an oblate spheroidal. They are the same thing only one is suited to a compression driver.

thanks for all the help!

can anyone recommend any cabinet makers in the new york area?
