Hi,

Thanks for the response !

Did some modifications:

1. Adjusted the front baffle so it fits the 604E?s.
2. Added 3/4 inches to the side panels. (I?m not any good at Vb and so on - If I?m off please let me know)
3. Added brackets on both sides + additional bracket between front baffle and rear panel.

Does anybody out there know the dimensions on the side brackets in the original 612C?
Should I put in the bracket that goes across the whole enclosure ( one of my first questions ) ?

I will use GPA?s crossover and will probably use a pair of monoblocked Quad 303?s as power amps.
