Rodman99999, my question to you is, have you seen and/or heard any of his work?
Yes, Bill changes the T/S parameters of the driver. Completely? Every situation is different, and warrants a different solution. Negating the designer's alignment and response goals is an assertion that seems to cross the line of what can be inferred in the effort to dismiss his work out of hand. It also ignores the fact that most OEM drivers are not nearly as close to meeting their specification sheets as we hope. Beyond that, there are parameters Bill optimizes the vast majority of people have never encountered, are not captured in a specification, and that OEM driver and loudspeaker manufacturers do not take into account.
Bill Legall, doesn't advertise it, but more than a few high-end audio loudspeaker manufacturers turn to him when they have a driver issue themselves.
As I said earlier, Vandersteen loudspeakers are a specialty of his. To hear the improvements he has made for many people over the years in the Model 2 and 3, which actually transcend the drivers themselves, shines a lot more light on the subject that my words can. Suffice it to say that a lot of people have changed their minds about purchasing a new pair of loudspeakers after their Vandersteens were modified by Bill.
