This may seem mental, but I got the bright idea of closing both 2-10 chambers in the 5410 cabinet (4-10s around a 1-15). All I have to do is cut some plywood to the right dimensions and screw the pieces in with some silicon sealant. This would give me a ported 15 in the middle, and 2 sealed 2-10 chambers (like an Ampeg). This should give added punch to the 10s, and the low end of the 15. Does it sound like it would work???
