Upper bass horn

[noviygera]

Hi I'd like to explore the options of changing from Edgar 80Hz straight horns to something else that meets the following criteria:

Least compromised design in terms of sound transparency, neutrality, dynamics definition. Efficiency and low distortion, obviously important.

The upper range of the horn shall be around 400Hz, the bottom range shall be determined by the depth and height of the horn (design) but I would like to have around 80-120Hz usable response.

The available space I have under my midrange horns is around 35" tall, 30" wide, 35" deep.

I am not at all knowledgeable in horn design so I am looking at buying an existing product that meets my need or getting a proper design and taking it to the woodshop for production.

What would be the least compromised design for my needs? 15" driver vs smaller drivers? Flare type? Compression ratio?

Thank you,
Herman

You should get a decade of bandwidth. 40-400 Hz.
A Klipsch Jubilee bass horn will do that for you.

I have read many times that folded horns are very compromised in terms of sq, especially if playing over 200 hz. True?

Does John Hasquin share his designs openly? I am looking for a rectangular tractrix horn, probably to be be made from glueing MDF templates.

above 200hz ?

300hz and above is 'just' midrange, and even a small 5" is barely moving

[noviygera]

That's right

So why not just make a proper horn without folds? Any designs out there to cover below 400hz and fit 35" tall, 30" wide, 35" deep spot?

I have an idea about a line source thing with horn mouth on its side

basicly like this
but is calculated to use backwall for support
or else its not possible

OK, looks good, even though it's a folded horn. Is there more information on this design?

experimental, for my bass guitar, and less critical

but might be better than that
will be tested later

if interested, I have construction pictures
there are a few details that could be changed to make it easier to build
I can tell you how to
but other than that...

ok, just for you, I made a few changes, and 'illustrative' drawing

its shown with 4x 12"
but expencive

could be 2x 15" would be much better
