Again, pink noise is the source, filtered through 4th order slope high and low-pass filters between 900 and 3500Hz. The system has around 500W RMS through it (we're maxing the amp...) Full thermal equilibrium is achieved within an hour with the steelwork, coil, magnets and dome all operating at 115 degrees Celcius (or 239 degrees Farenheit), which is pretty hot. This driver continued at that temperature for four hours before the amplifier hcalled it a day...
Speaker driver design 10 years ago, a decade of legacy, own a prestige.
