[QUOTE="Uwe Riemer, post: 212275, member: 394"] 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 [/QUOTE]
