So blog partner goes into the future with High Res digital and I work backwards to the roots of sound reproduction. This is how we imagined Audio16 in the outset, two angles of the same subject matter.
This article dates back to 1928 when the WE555 was hot cakes and as the article says way ahead of the competeiton at that time. The fact that this drivers is today still unbeatable seems unbelievable…but true..okay it has its specific applications as the articles puts it, long horns with low cut off…but when that condition is reached its a magic combination…

I love this stuff and reading up on the early pioneers who built such wonderful creations that last the test of time. Recently I’ve been reading up on acoustics, it plays such an critical part yet its the least understood and gets minimal attention for the most part.
Very cool. btw, the BSTJ article referenced is in this issue:
