Default frame double horn for two 8"

Hello,
a new idea for a double horn,
looking more complex but easier to built as a Saxophon

a lot of softfibre is used, so easy and cheap.

Opinions?

I love how all of your horns are folded- clever and elegant. It's good to see a design for eight inch drivers. Do you have a particular model of speaker in mind for these? What are the overall rough dimensions?

You take some heat sometimes for always offering your designs as solututions to a poster's questions. I understand why some of the regulars on this board may get a little impatient with someone tooting thier own horn, and your designs, at the very least, look intriguing, but I never see any feedback from anyone else on your cabinets' performance. I find myself suddenly with a lot of time on my hands, so I can take on a project or two. I've got a few different 3" and 4" drivers laying around, including the Pioneer A11, five different Tang Bands, and a few other random guys. Got a suggestion for one of your cabinets? I'm interested in making a comparison with the few different horns and BVRs I have now- Buschorn, Z-Horn, Olivia, Gabriel- I love to mix and match and contrast and compare. I would be interested in adding one of your models...

I purchased the plans for Schalmei Sat and am impressed and happy with them Using the Visaton B200.

Horst has been around awhile and has the experience.... he knows what he is doing.

Hello,
I was in Hamburg for business and decided to meet Horst for a listening.

Very nice and valid. They sounded good driven with common amplification and nothing special. They produce good bass for their size. It was deep and controlled and there was no reasonance whatsoever.

I bought the designs for the saxophone but I think I`ll eventually build these.

Thanks again Horst!
Tschuss!

Default rdh20 or lowther academy or other double horn

hello,

I'm also very interested by the designs of Horst and I'm always glad to have a feedback about them.

Do you have comparison with other double horn like lowther academy ?

I have currently a lowther mauhorn iv with ex3. very nice but I d like to have a wider sweet spot and I'm looking for some king of "panoramic" sound like in the lowther academy.

In this respect, the RDH 20 looks like a very nice design (at least on paper).

regards

Default Rdh20

Hello,

thanks Andrew,
and Matthew for the visit and feedback.

i complet the RDH20 side, have a look.

The academy is no double horn and has
less bass and a 10 kHz peak.

planet 10,

iVO wrote,
parts:


Some things to note about this design: There is a forward-firing and rear-firing driver. Depending on choices of the builder, the rear driver can be a woofer or a second fullrange driver.--- The two drivers drive two different horns, of different length and expansion.
The idea is that the horns have different peaks and dips and fill in each other's weak points. ---- The inside of the horn is largely made of soft fiberboard, to reduce enclosure sound. The inner horn rests on the outer section via a panel of soft fiberboard, which decouples it. Also notice how the horn mouth is wrapped around the entire enclosure. It is relatively large, yet the enclosure the driver sees is relatively small. Finally, I think it is a beatifully proportioned horn, which draws much less attention to itself than some of Horst's
other designs.
