Hello, I have a pair of the SEAS L21RN4X/P that I bought a few years ago. I want to build a pair of subwoofers like the CAIN&CAIN BAILEY. Please share any informatin you have in this direction. I have a pair of plate amps @ 300watts each. Regards Peterpan
Hi,
Download WinISD Pro and play with it. Your drivers are in there.
300W is overdoing it for those drivers. (check it in WinISD Pro).
Looking past the marketing BS the C&C subwoofer seems
to be entirely conventional, just an unusual form factor.

I've been looking at building a sub with the L22RN4X aluminium cones (I have a pair but one has been over stretched I think). I think 4th order bandpass looks good (from memory I had 2 chambers of around 10l each and tuned to 50ish Hz for one driver), sensible group delay, cone excursion is limited by the sealed chamber and if you have a pair geometrically it work well in a 3 chamber box, the centre chamber beingcommon for both drivers and sealed the outer chambers having the tuned ports, BUT you can rigidly couple the drivers together in the centre chamber by removing the phase plugs (they are just glued in) and fitting a spacer tube between the magnets and a threaded rod through the pole pieces to lock the drivers together. this means the inetria from one driver moving will be canceled out by the other, this reduces machanical vibration quite considerably.
