[quote name='alexclaber' post='465976' date='Apr 18 2009, 10:57 AM']I'm using the 3015 in the Compact, Xmax=5.9mm and extended upper frequency response. The Schroeder 1212L cab no longer uses the Deltalite II 2512, it uses the Celestion BN12-300S, Xmax=2.5mm. Excursion limited output is basically dependant on your total cone area x excursion, so the older Schroeder 1212L cabs can match the Compact for this, whilst the newer ones have only half this volume displacement.[/quote]
When comparing specs for drivers from different manufacturers you really should make sure they are measured in the same way. The Celestion xmax is the voice coil overhang, a figure that is quoted by every other speaker maker except Eminence. Eminence uses a method that can give a figure up to twice this.
