The construction of a multicell horn

Wow Petter!! Once a gain stopping by to take a look at these and thinking your workmanship has to be right up there with some of the best ever here at DIY!!! You make it look easy, and the rings to use as clamps are one of those simple ideas that just seem absolutely genius.. Like a great guitar player you make it look easy and simple when in fact it's very complex and challenging.. Excellent job dude!!! :)

Edit: It would be awesome if there was a section here at DIY for the best of the best sort of thing.. Where some of the most stellar and complex builds here could have a showcase.. Somewhere to show off members accomplishments that are just that much more than a cut above, it could be a speaker, amp, stand, turntable etc etc.. The Rolls Royce of DIY !!

:)

Dear Petter,

thank you so much.

And that was very fast, too.

I can open the file.

I will post pictures, if I have build these horns.

I like BMS drivers, the BMS 4550 is a 1" driver.

Can you help me with more details how to connect the drivers to the Multi Cell Horns?

Last time I use a round horn with 2" but BMS 4550 is 1".

I use a adaptor from Beyma.

No problems with that.

Sounds also good.

Thanks again Petter,

Okay, now I understand the system.

So, I can use a midrange compression driver.

There is a good 2" BMS 4591 midrange driver - 200 Hz to 9 Khz.

Use best arround 400 Hz to 5 Khz.

With a crossover I can go 400 Hz to 3 Khz.

Than add horn tweeter like you.

I also have a very similar horn tweeter like you.

Made by a friend.

Also uses a BMS 4524 driver.

I like BMS because, it sound really great, for much less money than the "big boys".

Hello Petter,

is it possible, that you can help me with the spreadsheet for a "single" cell horn?

I have long time the idea, to build a horn like the Klangfilm horn.

As sample see the horn at my Klangfilm KLL 430 speaker.

The horn in the front is arround 400 mm x 400 mm.

I hope you find some time.
