If you are going to do something like this then it would make sense to have it firing backwards & make use of the corner of the room in the way Carfrae did some 15 years ago.[IMG]http://i75.photobucket.com/albums/i318/murrayjohnson/big-horn.jpg[/...

[quote user="guy sergeant"] I don't think I'd be tempted to make a back loaded horn to begin with. [/quote]
Yep, it is what it is. The back-loaded horns might have as convoluted back path as Scriabin music is but the sad truth about them is th...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

I have listened to some expensive speakers from B&W, Wilson Audio, Dynaudio, and also owned the SF Amati, you know already. Musically these ones were more musically interesting to me than any of the others, but still weren't something that comple...

I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to defy the laws of physics...

I just love the way this Carfrae looks!I have been tempted to make something similar, but turn it into a front loaded horn (of course), say turn the driver around and add a back chamber on the back of it. Make a nice volume tuning device. And then...

[quote user="Vasyachkin"]the only real questionable aspect here is adding a second set of back firing, inverted phase horns. mathematically speaking it is what the design "needs" but of course the real question is - what does it sound like ? that's...

This project started in 2007 as an attempt to demonstrate that drivers different from the widely accepted low-Qts ones could be used in a back-loaded horn enclosures.Visaton BG13P, a cheap and easy-to-get (at least in Europe) driver was chosen, basic...

So, it will be a single-ended triode amp and in future possible DSET, right? YesOK, but you need to understand that you will pay the “minimum proximity” penalty for this. Yes, this is something Jeffery warned me about, "Romy has that vertical thing r...

Dominic, I did not use Lowtheres on my own and am familiar with Lowtheres only by observing of what other people do. Unfortunately, among what I have seen. Lowther was used in some strange ways. For whatever reasons people feel that absences of a cro...

[quote user="js"]Thanks for the reply. I'm using a Jabo KH-55 horn for hf/upper mid, so I think I'll have to experiment with different size chambers. Beyma quote the volume displaced by the driver as 5.5 litres, so I'll start by trying a 9 litre (g...

Paul, I am no expert on tapped horns but I think the main (40 year old) principle is that you join the back wave of the driver with the front wave, now in order to have the 2 wave fronts meet, the back wave should travel a certain distance depending ...

I never seen the polyethylene drivers but I would not say that it would be a joke, I would rather say that I have no idea what to expect. The SL600 MF driver is a polyethylene-like driver and it does have some interesting qualities, Sure it you drive...

You have identified the tricky parts -the transistion between the front and back horn as well as the throat of the front tractrix horn. A one to one throat with the front horn works best with my coaxials and a short 1.25" straight 'ring' ...

They showed this speaker at the Munich High End Show last year. They did not talk about the tweeter crossover frequency. The yellow cone Fostex driver is used from the low frequency limit (they claim 32 Hz) to 250 Hz. The back loaded horn is 3.3 mete...
