Klein Bottle enclosure

[turk 182]

after checking out Acme Klein Bottles i was wondering if the shape could be used as an enclosure for a fullrange driver possibly creating a backloaded horn assuming an exit is created.

i do want a klein stein for a beer mug!

See Nelson Pass's "Kleinhorn."

Why not? Make a flat surface on the large part of the bottle for the driver and the open part becomes your horn. Not sure it would be any better but it has a novelty effect.

If you mount the diver in the opening, leave it sealed.

sy thanks for that link i guess it's been done in a larger scale then i was thinking of by a wide margin.

cal i was thinking the other way around; mount a small 2 or 3 inch wideband driver on the small (throat) opening and create exits around the driver into the large part (mouth).sealed could also work...
now i need to find a 3D printer!
or maybe just get some klein steins pour out some margarita's wait for spring and think on it somemore....

A Klein bottle is closed if you put driver at mouth. In which case it will be kind of like a sealed TL (if long enough). One could mount driver on wall of bottle and let mouth/neck serve as vent in a BR or TL or BLH. The aesthetics would look great in a real blown glass enclosure so you can see the Klein bottle topology. Otherwise looks like a bottle with a loop handle.

Hey turk,

X and I said the same thing. We must be right.

Hi Turk
You might be interested to see this post:http://www.diyaudio.com/forums/pass-labs/166784-pictures-your-diy-pass-amplifier-182.html#post3438566
I asked him about it and it's just a scaled down version of the 'HUGE' one Mr.Pass designed.

Ignore the fact the link says 'Pass Amps', Klein pic is about 1/2 way down the page.

sippy and sy like the big versions and cal and xrk don't lke the idea of "creating exits" around the driver to create a "horn loaded bass port". why?
klein stein or not i guess i need a drink!

 

[xrk971]

I guess I don't understand concept of exits around driver? Driver at bottle mouth and holes around the mouth into main volume? That is actually closer to a mass loaded TL.

 

[turk 182]

sorry no scanner no cad i hope the attached photo is ok to depict what i was thinking.

depending on size could it not be turned into a mid horn or mid bass perhaps?

i keep thinking of it like a long back loaded horn

 

[sippy]

If you read Mr.Pass's artical, he folded the horn the way he did because of space constraints....

Now, If you could get a glass klein blown and make it into a 'Nautaloss' style enclosure, that would be a really funky aesthetic.

 

[turk 182]

i keep envisioning something more "steampunk" looking reminiscent of Western Electric theatre horns or "stained glass" style construction perhaps.
i wonder how much foamcore it would take to mock one up??

 

[Octavia]

foamcore a western electric horn…i like where this is going

When I saw Hippy's 'Micro Klein', I sent him a pm asking for more details, quote:

the demensions are based off the ones in the pdf, except everything was devided by 3.2 which scaled it down for a 2.5" driver

He also said that the driver used had no details on the 2" drive unit he used other than it looked like a $20 Dayton.

Hi. I'm reopening this thread to ask about a klien Bottle enclosure I've seen on Thingiverse page to see if anyone has any ideas about it and how one might go about calculating/modeling this type of enclosure?

I'm thinking of printing one out to try with a decent 2" driver. But I've just found I have some TC9FD-18-08 on the shelf, so was wondering about scaling up this enclosure to try out. Any thoughts?

a sealed TL

But with a geometry opposite of what you would really like.Kleinhorn opens up the bottom (both X’s and my pictures, and then sizing everything to be a uitably sized horn.

There is a parametric equation for the Klein bottle that can be used to generate 3D models.

I have applied it to a 3D graphing program and it works.
