Post Subject: The HobohornPosted by Rewind on: 8/23/2013

I built a prototype of a Avantgarde Trio in newspaper and tape, with the Beyma CP380/M, Community M200, and the Fane S 8M, and I also used a Behringer CX3400 and a 45 tube amp. CX3400 is soon replaced by digital active XO.

Paper may have made the midbasshorn a little flabby/muddy sounding. The Fane 8M did not sound as clear and fast as the compression driver in the Goto S-150 wooden horn. But that was not a fair comparison. The backchamber was wrong and the paper Avantgarde midbass horn was not as solid as it should.
One good thing came out of the newspaper experiment. I have always thought compression drivers had a harsh quality to them. But using paper horns above 500Hz made the sound very soft and smooth, but still hornloaded. Have a listen: https://vimeo.com/m/72501089

In a few weeks I will compare the JBL 2204H 12" direct radiator, and a wooden Avantgarde Trio midbass horn with a Fane 8M, and a wooden Goto S-150 200Hz horn with a compression driver, next to each other. I have heard all three of them separately , and my vote is on the Goto S-150 or the Fane. I can't be sure yet. I will also compare the Yamaha JA6681B and the Community M200 in the range ~500-3800Hz. They may not fit in the same horn, even with adapters, but I want to use them in as similar horns as possible.
