I got curious when I came across this statement somewhere on the internet as I assumed phase plugs are centred with the cone. Perhaps there is an advantage in having a small offset, for the same reasons one offsets a driver in a baffle. Anybody got any additional insight to share ?
“I recall, however, that Scott Fraser said that the phase plug mounts eccentrically in this driver, which made aligning the cone especially difficult. “

The lowther phase plugs have a captive bolt which fits into corresponding threads in the polepiece, so hard to do anything with centering.

Hi Dave, That sounds like a good approach to the build - my follow-up question is whether you, or anybody else is aware of Lowther (or anybody else) having designed their phase plug to be offset from a perfect coaxial ?
