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
