[MatthiasA]

how old are you when you say i am young ...
i think its a good time to build loundspeakers

i laught about all the people in my age
with no experience and knowledge
who build many cheap speaker
they think the cheapest the best *lol*
i am very thank full about this forum !!!
its great !!!!
i think home and pro audio is the best and JBL is great !

i am searching for a amplifier for the S2600
i think about a Yamaha P3200 / P4500
oder a JBL MPA ???

greetings Matthias

Pics about the Crossover and the Horn adapter are soon available !

It reads to me that Matthias wants to know where to place the woofer, i.e., exact dimension of centerline of the driver from bottom and edges of the cabinet.

Matthias: It is unlikely that the "midplate" is solid, rather, just a brace. There would be little purpose in dividing the box into chambers since the horn/driver is solid.

Amplifier? JBL 6230. They sell on eBay for less than $150. Originally, they were $600 or more....

in the pdf of the S2600 the midplate looks like solid !
and in the pdf of the S3100 the midplate has many holes !

Yes, so it appears. Someone who has one may have to check to be sure, then, as you request....

[MatthiasA]

here the s3100
you can see the hole in the midplate
and damping material near the horn !

just ive made the horn adapter
it isnt finished yet

[Bernard Wolf]

Not finished yet ?? Just kidding..

For your info, I am 55 yrs old and counting. As for your need for that inside dimension for the sealed bass cab of your 2600 project I now understand your concern as it seems that the cab is closed to meet the tuning specifications. I suggest that you post a private message to some of the S/2600 owners on this forum and ask if they might do you the favour of opening up theirs and getting that spec for you. It should not be too difficult to do. If I am not mistaken, a couple of these owners are in Germany.

Good luck.

Simply OUTSTANDING young man!!

@Bernhard !

ive sent several messages to german people too
but nobody knows the distance .... from the plate inside ...

greetings matthias

[Bernard Wolf]

What I don't understand is that if the plate is in position how would you attach the driver/horn to the back of the cabinet ? I mean the first time when building, OK, just put the plate in after. But what about servicing them later? You would then need to take out the bass driver, then the plate and finally the horn? Sounds kind of strange to me.

As for those measurments - you may just need to guesstimate it. Too bad those folks in Germany won't do it for you. The 12'" bass driver cannot be that heavy to remove as the 15" is.

[MatthiasA]

in the back of the cabinet
there is a hole behind the the horn!
about 18 x 25 cm - i think its more than i need
to change the horndriver 2426H !!!
in this hole it is a ferrit brass in german "messing" plate
which close the hole !
with about 8 or 10 screws !
the plate is also painted !

greetings

[Bernard Wolf]

That makes sense - but how would they have done it in the 'factory' 2600 I wonder. The reason I ask has to do with that 'plate' we have been talking about. You know, with the 3100 the plate is open and thus you can get your hand up in there- but if it is closed like the picture shows of the 2600 ... then what? I think you really do need to get someone out there to open it up and find out what is going on in there you.

Bernard

[MatthiasA]

in the Orginal S2600 the Plate inside is solid !
and you can remove the Horn with 12 or more screws !
with the removing of the Horn you can change the Driver 2426H
and then you can screw the Horn back to the cabinet

in my S2600 the Horn will be solid on the cabinet ! nothing to screw
and i will make the ferrit plate in the back of the cabinet to change the 2426H

do you understand ?

greetings

[MatthiasA]

but who can me give the height of the plate inside

[Bernard Wolf]

Matthias - yes I understand , but the point I am trying to make is that in the S/3100 the 2426H is ATTACHED TO THE CABINET as well as the horn which means there must be a way to get at it. If the horn is separated from the bass in the 2600 with that plate, how would one undu the driver ? My point being that perhaps the drawing for the 2600 is incorrect ? Have you considered that ? Sure would be nice if someone could open one up for you.

Hope I'm not just confusing things for you
