Dual action Tapped Horn (New ideea..maybe)

[rvrazvan]

I want to explore this topology but i will need some help in order to aproximate an result.
the picture say's it all.

What would be the advantage over one TH with the same dimensions with two drivers as your dual TH ?

[KRhirschkorn]

Looks like it would work fine. whats ur math for tuning and so on say.

That's an interesting allignment.

if you reverse one driver the "average driver" is a flat piston.

A downside for PA mostly would be that if one driver stops you effectively get two off-set horns.

An upside could be that you can use different sized drivers (see were that takes you).

Makes me wonder:

You could use two drivers in a single tapped horn and have the other side of the diaphragm load something else, say a closed box (or a reflex) to change compliance / excursion. Differerent enclosures could mean you could tweak the ratio of the throat : mouth level/ contribution?

Thinking out loud, it would diminish the tapped horn double Sd-effect but would result in endless days of experimenting, possibly finding the next step.

Best regards Johan

One advantage of this is that you can have a ...straight tapped horn if you like.
That is not possible with a normal tapped horn.

The math for this....is way out of my league. Time to learn akabak !

Yea I hear you. I can build ported cabs all day but thats about it. well and sealed. lol

Isn't that a downsite that counts for almost all PA subs with multiple drivers and combined spaces?!

SO.... back to the problem. any ideea how i can model this?

I think you'd see more of an advantage from a push pull alignment of the same volume...

You can do it in Hornresp.
Look at your "unfolded" diagram. Cut it along the diagonal partition. Each half looks just like the schematic diagram of a tapped horn in Hornresp, right?
Now double its width (cross sectional area) and use 2 drivers.
In other words, a "conventional" tapped horn with two drivers and the same dimensions will perform identically (at least in simulation) to your design.
