DDBH-T17F-AD
39.37in x 10.2in x 16.7in (1000x260x425mm) HxWxD
Victor
60in x 9.5in x 17.5in (1524x241x445mm) HxWxD
Victor is ~ 20" higher than DDBH-T17F-AD but if I'm not mistaken only issue could be that it should be ~ 10' from listening position for the double mouth back horn to come into focus therefore I would guess DDBH-T17-AD should work better in a smaller room
... can't help wonder how 166EsR would do in JOAN horn which I suspect is closer to the Austin A166 horn some have used with 166EsR

I’m new to this speakerdesign. But isn't this a transmissionline and not a horn?
Also . The curved sides. Are they purely for esthetic reasons or are they functional?

It's a horn. And curved sides are funcional, because form horn mouth. Very clever design.
Designers explained this before.

It acts as a transmission line for the lowest frequency range. And as a horn a bit higher up.
A very clever design, and very well packaged

You can find some Ron Clarke's design and contributions here:

He developed the curved shape to virtually increase the size of the mouth.

Ok.Thanks.Looks interesting and not to difficult to build.I got a pair of Lii f6's lying around.Don' t know if they would work though.
In the broadest sense of the way TL is being used these days (as quarter-wave = TL) a horn is a TL, but The Frugel-Horn is a horn in the stricter sense, and uses a lot of the tricks of the Pioneers.
The case with all small horns. Scott (@Scottmoose) would have to step in to tell us how much.
The purpose of the curved shape is to make a high aspect ratio rectangular mouth look more like a circle.

Scott has explained this numerous times over the past decade-plus that this series has been around.
Thanks Dave, just to understand better: the curved shape makes the mouth look like a cirche with the diameter equal to the height of the speaker?
Or with a circumference equal to the circumference of the rectangulus (front/back view of the speaker)?
Has the procedure to obtain the radius of the curve ever explained?
Thanks
Hello ,
Could you please suggest me a build with the MAOP 11 which would provide an effective low end .... 40 hz or below .
Regards.
Frugel-Horn XL or DDVP-15 or SDDBH-T13.5R-AD.
Frugel-Horn XL and DDVP-15 are about equal in low frequency.
SDDBH-T13.5R-AD extends to 30Hz, but is not as tight.
Sure I am keen to get a good low end from the enclosure . The mids and highs are great for the driver .... the bass response is cabinet dependent .... hence the worry....
True .... Dave had query do the Voigt tubes here the sibelius replica or the DDVP go as low as the FXHL....
A lot will depend on room. FHXL has greater extention potential but they all go pretty low.
