Devore Orangutan Clone?

[superlian]

Our "Divorced" received many acclaims at the Horten 23 HiFi show DIY-apt. The XO is none of the above mentioned, my own spin-off.
An American couple where the wife is a musician stated that this was the system she thought sounded best on the show.
Others liked the big powerful system better, no surprise

The larger system are all Bliesma BE domes in MTM together with AE bass-tower and SEAS ROY x 4 subs. An awesome system indeed (not mine).

Best of the show in my opionion to 👍

WOW!!!

Best in show above everything who is normal

At home he has 8 x 24 inch woofers in 2800 liter enclosure:

One of the best systems in Norway.

Orangutan exterior dimensions. Three 1" dowel braces front to rear around the woofer. Shelf brace 1/3 of the way from the bottom. 19mm BB throughout. Hate mdf dust. 2 ports in the bottom 2.5 x 7.

Woofer has a 1.0 mh 18ga coil only. Tweeter is 3.9ohm into 8.2uf, followed by RL shunt that is 6.8ohm-. 68mh and shunt after that shunt of. 56mh.

I found the more complex xo superior to various XOs that let the woofer go.

I have the xo external, because I am never done.

This is very nice work.

May I ask if you can share the crossover diagram please?

Coincidentally, I'm just getting back to this. I'll post in the next few weeks if I make changes.

Regarding crossover frequency and off axis response. This is from Stereophile. The crossover is proabably between 2,5 and 3K:

I can see that the Morel tweeter is much deeper than f ex Seas DXT. The measurements are quite similar.

That DXT remains something special… keeping DI constant from 4,5k.

This is very nice work.

I have settled on the XO pictured in post 172.

Love this thread. About to start work on mine. Has anyone looked into adding a super tweeter like the O/Reference has?

I built some earlier this year which was a fun project. I’ve since moved them to around my desk in the office.

pretty baffles

Next step: Bottom ports (additional stiffeners not shown)

This was my first speaker build and not putting in bracing inside was definitely a regret. I saw how it didn’t appear in the originals to have any internal braces and used that as justification to be a little lazy in my own construction.

 

[superlian]

You can use carpetglue and 3 mm bitumen sheets on 2/3 of the surface inside instead of bracing

3 mm bitumen sheets on 2/3 of the surface inside instead of bracing

no, no, no...

That has a completely opposite affect. Increases mass without adding stiffness lowereing the frequency of the panel resonance and decreases the Q.

A brace divides a panel into 2 sunpanels, the shorter dimension increasing the potential panel frequency. Q stays much the same.

The affect of the first is to make resonance smore likely to be excited, and more likely to be heard when they are set of.

I was thinking BBC style 😉

 

[planet10]

It works in a small box, not in one that does bass.

And he would have had to start with the plywood.

An alternative design for JBL disciples:
The blue baffle is made from through-dyed MDF.
The cabinet is made from waterproof mdf boards, veneere is walnut.

A model with Seas T35 tweeter in Jantsen waveguide. XO is under development.
