3 way front loaded horn help

3GGG · 10th October 2010, 10:54 PM

With my TT nearly complete Im planning a horn build. They cant be extremly massive with 100cm horns or 2meter bass horns due to wife approval.
Here is what I am thinking of so far, any help is appreciated as I have never built speakers before

For the highs these drivers Fostex T900A
http://www.fostexinternational.com/d.../pdf/t900a.pdf

For the mids a horn an AH-425 from Azura horns, although I am undecided on which driver to use
Azurahorn -Le Cleac'h Acoustic Horns - Products

Then the bass is the hard part, i would like to keep the build to a maximum width of 350mm and under 1600 high, any suggestion?

[1] A low WAF is incompatible with placement of a real, all-horn system in your home. So, work on increasing WAF. Jointly audit some all horn systems, and take her to dinner afterwards. Involve her in the development process. From time to time, ask for her opinion on enclosure aesthetics and how to improve it.

[2] The dimensions of a real bass horn, that does not get its extension from a room corner:
a. will unload the driver at about 100 Hz and below
OR
b. will not physically fit in your listening space.

Use a corner horn, otherwise, no horn at all for bass reproduction.

[3] At the bottom end, use a muscular transistor amplifier and servo control for a power source. A wimpy tube amplifier is not going to help you here, particularly if footprint reduction remains a requirement.

Regards,

Does such thing exist?

A bass horn that plays low enough, and also high enough to hand over to AH425, and also under 350mm wide?

Does anyone know what type of enclosure this bass "horn" is

Avantgarde Acoustic Hornlautsprecher

The ads tell you it's a short horn with a rather powerful amp and EQ circuit.

CLS · 13th October 2010, 07:16 AM

Indeed.

Download the hornresp and play with it a little. You'll soon find out a 'real' bass horn is HEEEUUUUUGE.

Yeap, im aware a true bass horn will be massive. I really need to look past a horn and maybe just look at the best way to get an efficient bass driver to deliver maybe 40hz an up.

Has anyone used either of the following horns or drivers

AH 300, AH 300 Acoustic Horn

DCM 50, http://www.cadaudio.dk/dcm50.pdf

Fostex tweeter, T500A Mk2, http://www.fostexinternational.com/d.../t500ammk2.pdf

After reading the paper by JMMLC with referance to the ETF 2010 festival I feel one of the Le Cleac'h horn's may be suitable. Has anyone got experiance with this horn designand the DCM 50?
