Hi,
I have no foreign language, so here goes.
Do you have two exit mouths? One in the front and one facing towards the corner?
What effect does the corner have on the EXTERNAL horn flare?
Is AM2.1m the two mouth areas added together?
Is AM3m the corner flare exit mouth?

Default corner horn

Hello Andrew,
right.
both mouths left and right
open in the corner at 2,13 m
than it opens greater than simulated
to 3 m approx. 1,5 qm,
so the horn ends not abrupt into
the room.
I listen to it 7 hours, it is not
so direct and punchi like the
alphorn but lighter, easier, more
transparent and a bit
more contur, there might be
also a frontloaded effect in
opposite to backloaded.

DorinD: Thanks

Shouldnt you add a top plate so the horn path really extends to the front instead of going "over the top"of the cabinet ?

Ah-ha,

I didnt know you were an expert on horns already

What do you mean by "frontloaded effect" ?

I like transparent sound

Does this cornerhorn do bass better than the other shapes you have tried (natural bass reproduction)?
The mouth is very large so this might explain why you say less punchy than..


Regards,

Coolin

it might be that the corner horn
make better contur and transparens
because the direct sound of the
driver by backloaded is lost.
You listen only horn.

I tested it already with a friend
fantastic sound, effortlessness,
no location of the bass, super.
i know only german language to describe.

with the HORN-sat with B 200 Visaton
excellent, when the HORN sats make 0,5
Watt impulse, i am getting afraid of my neighbour.

For me the best bass i ever constructed.
The box is only 196 L with a mouth with 1.5 qm !!

Next: measurement in a 80 qm room.
