@normand Looks very useful ! and tidy build.
Those 'rotted foam' surrounds were used by so many manufacturers and proved to be the weak link in otherwise well made drivers.
After having to replace them (twice) on the passive radiators in mine I spent a lot of time finding, fitting, and re-configuring them with rubber surrounds.
On the other side of the coin my very first set of drivers and speaker build from 1978 are still working and in daily use. Kef with rubber surrounds...and the occasional application of oil of wintergreen to keep them supple and within spec.
