TinyHorn

[TundraLTD]

Have a 12PS100 laying around and decided to do something with it. I worked in Hornresp and akabak today and came up with this Akabak script. Let me know what you think. I did draw it out in Sketchup as well

An externally hosted image should be here but it was not working when we last tested it.

External dimms? Response looks good for a low midbass / subwoofer for portable rig that won't be playing much dub!

In light of recent talk with cone correction plates, I like the fact that the pressure on the cone is more evenly spread instead of having half the cone open past the s2 point...

 

[epa]

looks good tundra.
nothing wrong with it

 

[TundraLTD]

ext. dimensions are 24"x22.5"x15" I put a cut-sheet together and others docs to make it easy. I'll put them together after work

 

[TundraLTD]

Here are some of the files

Plans zip file removed by request.

why?

 

[martinsson]

I agree, why ?

 

[TundraLTD]

Several friends that make their living in the industry had issue with it. I used to work design/install and still work on special projects for them when needed. We didn't make it a big discussion and I don't want to burn my friends and contacts I have. If you would like a copy of the plans and have no intention of using it for profit I'm still willing to share it by request. Hope that is a simple enough explanation

 

[martinsson]

Sorry to hear that, personally i feel that sharing knowledge, idea's and projects is what drives the development, thanks for trying, it seems to be a very nice design, and it certainly deserves it's place in the DIY community.

A bit familiar perhaps?

Tom

 

[martinsson]

12" TH, 24"x22.5"x15" and very similar response, now that I see it yes it's very familiar indeed, I did not make that connection.

A bit familiar perhaps?

Tom

That is exactly what was brought too my attention. I wasn't going to go into all the why

I respect you and your work and would never intentionally do anything to compromise either

Let me know if you'd like the pic taken down as well.

 

[TundraLTD]

A quick heads up to you all out there. Sending me a message bashing Mr. Danley and then asking for the plans doesn't fly with me and you will be ignored

 

[epa]

why would anyone bash mr danley?
al he stated was "A bit familiar perhaps?"
youre right tundra ,just ignore them.

Hi!

i have got this chassis lying around and have been searching diyAudio for a Speaker to build with it. The Tiny-Horn sounds pretty awesome, so it would be great if you could share the plans with me. This will only be for my private joy and for advancing my woodworking skills .
