Hello, it looks great, well done~~~

I have a few questions about the throat?

It seems that you used a lot wooden stick in the throat. What is the green colour glue? How to smooth the internal of the throat? On the other hand, i think that the wooden part between the throat and the driver will be apart due to the weight of the driver.

What is the green colour glue?

its a high power construction glue which foam-up !!!

How to smooth the internal of the throat?

with a lot of sandpapers :-)

On the other hand, i think that the wooden part between the throat and the driver will be apart due to the weight of the driver.

yes you are right, the same i thougt a week ago
therefore ive a opening in the backside of the Speaker
with a MDF Plate!
i glue the circle wood on the plate ! the woodenpart between the throat and the driver will never be broken !

you can take a look at the pics

You solved the problem, it is a good solution.


In fact, i had tried to make an Altec multicell horn before. I use metal sheet to make it. But, ringing is happened.

It seems that wooden horn will not ringing, i will make another one later.

[MatthiasA]

The woofer cab should be fiberglass as is the norm.. I use large ceramic tiptoes under my 3100.. they are about 2" diameter.

Sheet metal is just that , a sheet of metal perhaps 1/16" to 1/8" inch thick. You cut it to size.

Good luck with the Everest !!

[MatthiasA]

thank you !
should i take spikes or the wooden frame ?
the everest project must wait until ive my own flat or house...
in a few years ... but i will do any CAD drawings of the Horn!

[alltec]

Bernard is right, metal sheet is a thin iron sheet, it is so easy to cut it.

Your CAD drawing is really good.

[MatthiasA]

thank you!

[Bernard Wolf]

Well you may as well do the frame like JBL original equipment... you can always experiment with different footers from there.

Bernhard....
... could you please take a big photo of your JBL S3100 MK2's ground
(red circles in your pic)
that would be very fine
could you take a photo of the terminals too
yes.. i know iam stressing... sorry...
only this 2 photos

[Bernard Wolf]

Here they are: Don't ask where to get the tiptoes because I have no idea.. I do not even know what they are called. I found them about 5 or 6 years ago.

If anyone is considering trying their hand at building the S2600, I have a pair of NOS ME120HS woofers. I do not believe they are available in the US. I think Matthias Paid $450 Euros for "one" in Germany (over $500 US) I will sell the pair for $400 plus $50 shipping (continental U.S. only) Send me a PM If you are interested.

[MatthiasA]

hello mrbluster

yes the woofers are available in Germany
one brand new cost 450 Euros
if i had more space in my room for more S2600
i would bye yours immediately!!!!!
today ive bought the LX800 Reflextube for 24Euros
the S2600 is out of stock here in Germany

ive asked my parents
i would built a pair for them but they dont
want two new (selfmade) Loudspeakers...

sorry mrbluster....

greetings Matthias
