is this a form of rear load horn scoop?

You mean like HOG, RX18, S118, Superscooper, Shortman..

Right you are squire.. I guess everyone will switch from those to this one then, because its "far more scoop"...

Tony, thats what you've been doing wrong all these years, instead of producing well built, efficient cabs, they should have been more scoopish...

Gentlemen, please.

No idea what you're all talking about, to me, a scoop is a rear loaded horn with curved baffle, hence the name (based originally on the double 15 D55). Over time this has been eroded to mean any old rear loaded horn.

But I'm busy typing up some points that one could borrow from such designs (as Tony has said, people doing hifi are much more adventurous...).

Good day,

Lev im talking about Shortmans mini"scoop". THERE IS NO SCOOP!

Now enough of this jibberish / gobbledegook

Agreed.

Read the entire thing. If you need me to paraphrase one of his findings into laymanspeak, I will oblige. He explains reflectors, curved horn mouths, line arrays, why ply is reccomended, and all sorts of other information.

Regarding the term 'Scoop bin', does anyone know the origin of the term. I can understand why people call it a scoop, but as we know, it's not a technical name. And for the not so well informed, the sound does not roll out of the bottom by virtue of its shape.

Would it make any difference if the curve was left out?

The curve is just there to approximate the expansion of the horn, (if you unfolded a scoop it would be an approximation of a horn), so if you left it out the mouth of the horn would have negative expansion before. However, you can in turn approximate the curved panel into a sectional curve (If I am not mistaken, the RX18 uses a sectional curve).

But on the origin of the term 'scoop', I've always thought it was created when people saw the original JBL D55's curved panel, and therefore any rear loaded horn with a curved panel was called a scoop, which was corrupted to mean any rear loaded horn. Exactly who came up with the term, I don't know...

That's a Hi-Fi rear-loaded horn (no, them hi-fi folks don't use scoops). They usually fit fullrange drivers by the likes of Fostex, E J Jordan, Coral and Lowther, all of which are small 5-8 inch things that sound absolutely beautiful at home. That looks to me like a Fostex reccomended design, or some other one. Note the stepped bottom - these cabs are usually ridiculously heavy and stable, kind of like compressed ASS cabs.

Mykey, those Lowthers... I looked at the price list and...well....[img]smileys/smiley9.gif[/img]

On these types of t-line/horn speakers:
(most "horns",
including the Frugel-Horn are actually hybrid TL/horns. Below a given frequency the
mouth is not large enough to damp the pipe resonances giving undamped TL action.
Above this frequency the mouth becomes large enough to provide the horn damping and
you transition to a horn loading.)
