B&C coaxials

..... Use, would you be interested in sharing what sort of box and passive filter design you went with?

Hi Riley,
my wedges are built as vented boxes, never even thought about something different. I cannot share details, there is too much work involved, but here are some hints:
Enclosure:
Simulations are only for a start, then I build the prototype a little bigger and use milk crates to reduce the volume until I am there. Low end extension and max SPL roughly half an octave above tuning frequency will always be conflicting specs.
Placement of the vent is critical. I like the microwedge solution.
Vent area should be the smallest you can get away without choking ( clearly depends on amp power )
Damping material will effect tuning
Listening test to determine the final tuning should be performed with burned in speakers.
Having two prototypes to compare is a good idea, but be aware of sample deviations.

Have fun
Uwe
