Of cause it shall be mentioned in the context of thin there that there is always the ALE Acoustic solution. The Japanese ALE Acoustic make two midbass drivers: P1260 and P160.

The first and the bigger thing that I like about them is that Anima is trying to use the vertical-horizontal configuration where the bell of the vertical horn serves as frame for horizontal channels. I love this idea and had a number of my own th...

During the 2002 CES, late at night, a friend of mine demonstrate me something that was tying to address for a few years. It was a very different “tone” form a loudspeaker or I would rather say a different relationship between reproduced and auditable...

much for very detailed explanation of your horn theory. Let me present some

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

The upper bass horn has a Ceramic driver 18sound 8M400, the MF horn has an 18sound 2060A Neodymium magnet, tweeter is Beyma Ceramic driver and supertweeter is Fostex Alnico. The Leak amps are PP deep class A, we do have a...

Hi Romy,
Again, good words (don't want to kiss your ass ;) ). Though, I get your point and agree, one should not think that this winter picture means Goto sound cold (u never know what one could read out of it) .

[quote
user="jackydai"]My basic point is: the flare rate has to be coherent
right from the entrance of phase plugs. In this sense, not even Bruce and Sam

designed by diffe...
