Bass Horn

[Fredrik93]

Hi all I'm a new guy to this forum.

I'm 17 years old and from Sweden. I recently got the urge to build a bass horn which my father has told me about before. However, I'm an complete "noob" when it comes to horns and any sort of speakers. Is there some sort of "safecard" when it comes to bass horns? A drawing that you can't mess up to badly and isn't too hard to make.

I'm not aiming to do the best horn in the world, and i bet i wouldn't hear the diffrence so much either.

To put it all together.
Could some friendly soul link a bass horn plans to me that has been tested and are somewhat OK for a beginner to begin with?

Many pre-thanks / Fredrik

This is a reasonable size bass horn which should not be too difficult to build. To get much deeper than 50 Hz. will require a very large cabinet. Hope you find something that works for you and have a good time. Regards Moray James.
sorry my link did not attach. Design by Ernst Beck http://www.egbeck.de/15bhorn0.htm

as you have posted this in subwoofer forum, I suppose thats what you expect, a subwoofer

well, maybe your dad never heard about tapped horns

JBell's two ft. cube is a great looking Tapped Horn. The Lab Horn is a rather large complex design for a first build. A kllipsch Jubilee would be smaller by a little and probably less complex to build. I guess it depends upon what the intended use is to be. Regards Moray James.

Probably an apples to oranges comparison.

A horn is distinguished by high efficiency, length, and a large mouth. The TH design is interesting and to be commended, However, in many ways it is "not really" a horn (let's not argue about semantics not quibble over minor issues). The TH is not really meant for for an extended bandwidth. It is meant to have LF extension. The mouth is simply too small.

On the other side is an honest-to-goodness horn (K-Horn or Jubilee as examples). These have real efficieny (and the flip side to efficiency is low distortion). Additionally, they can play up to 400 to 800Hz. However, they will not play down to real low frequencies (unless the cabinets get huge and they are augmented by loading from boundaries).

I agree, it really does require an examination of what your intended use might be.

They are horns, if built as a horn. There are no semantics to quibble over.

The mouth size is not the reason for the high frequency ceiling.

Here I was thinking that a TH's increased efficiency over conventional designs, its
length which is in the same 1/4 WL as conventional horns and its mouth,which is large
but not as large as a FLH (yet so many FLH's designed have nowhere close to the optimal
mouth size) ,and compression chamber(area) would classify it as a horn?

or a "bandpass line"

but does it matter really ?
we need to hear from Frederik, about his needs
