Boxes look nice… What are the outside dimensions for the smaller box, and did you stick with the 4 cubic foot volume? How are you planning on supporting the driver (i.e. baffle only, or did you incorporate some sort of a brace similar to those found in Planet10 designs)? I have not worried too much about driver bracing/support in the past and would like to experiment this round. Dave’s logic behind coupling the driver with the back of the enclosure sounds like a good idea. I assume care must be taken to make sure the vent isn’t covered or restricted.
For my SDX15 cabinet I think I will build a 4.5 cu. ft., down firing cabinet (18” X 18” X 36” or there about). I also have a 300 liter LLT tuned to 15 Hz. that I plan to test the driver in too.
I am looking for a lower Q alignment, and according to Unibox using about 135 liters with “heavy stuffing” gives a Qtc value of about 0.55. Heavy stuffing to me means one lbs. per cubic foot. Does this ring true with the rest of you experts?
Really nice to see you using "real" wood for these cabs
That should probably be Planet10 drawings... Chris (driver designer) specified the boxes, i just dis the detail to get the sizes right and added the last brace from the magnet to the back of the box.Al,
sort of a brace similar to those found in Planet10 designs)? \
