Full-range or extended range speakers have many advantages that earned them a deserved reputation amongst music lovers. I am not an expert speaker builder nor an expert on acoustic theory but I have played with them: I used an Audio Nirvana super 10 FR driver to build a reduced replica (2:3) of the famous Tannoy Autograph enclosure. These corner speakers need a wide room to allow on axis listening at a reasonable distance and feel the very good HF that these drivers bring. The front and rear horn loaded design (bass horn being a folded type) allows for: even better sensitivity, wich makes the sonic presentation more dynamic; good integration between frequencies, the acoustic crossover is not apparent; a huge soundstage with good depth of image; good extended, ample and fast bass response.
There are drawbacks with this 2:3 Autograph replica: I think sub 40Hz bass is a little feble; you must use corners of the room to feel that "Tannoy bass".
So, I am devoting myself to the creation of a front and rear horn loaded fullrange with a diagram derived from the Autograph but that can be used in a different location from the corner. The enclosure will be BIG, but the sound deserves it.
It will look "Kleinhorn-like" but without the big tall horn, because my rear horn will be conceiled on internal foldings ;-)
I made a prototype for a 3.5" FR (actually I'm using a no-brand midrange to stay at low cost). The enclosure now looks ugly but has a magical sound :-)
The idea is designing an enclosure flexible enough to increase or decrease its scale to fit different sizes of transducers. For that I am using autoCAD. I am a complete beginner on it so don't espect much of the schematics :-D
It will also be possible to fit a bigger than projected driver with a little mod, provided that the front horn is increaded accordingly to fit the desired driver on it.
I am seeking help at DIYaudio.com forums because I need to simulate the bass horn response. In fact, I fear that I will have TOO MUCH BASS. I also want to play with different compresion chamber sizes, different throat sizes and different horn lenghts, to "fine-tune" the frequency response.
For now I am considering an enclosure good for a 6.5 incher...or maybe this same enclosure but with a bigger driver, like an 8" or 10".
I hope you like my effort and feel the need to contribute...

Hello Max, I looked dozens of forums and websites looking for plans to build a double 15" or 18" loudspeakers.I had no chance to find any answer in my neighborhood so I ask you some Help. I discovered your pics on DIYAudio I'm interested by Autograph corner horns plans speakers. Can you tell me how I can order these plans from you? What driver did you test in your assembly? Is it still available in the catalog? I'm on my way to build 2nd order filter for bass and 3rd order filter for mediums and hight Do you think it will fit to this project? Thank you for your answer and congratulations for the time spent on development. Thanks for your answer, best regards. B. B.
