i have been crunching some numbers figuring out what else i can add to my suburban build with what room is left that im willing to give up. im looking at either 2 aq sdc2.5 10's or 1 hdc3 10.
for the sdc2.5's i came up with a box at 2.91cuft after displacements. breaking it down for building the shared slot port in the middle of the box(i think i did this right) i factored half of the box area and half of the port width to figure how long for both sides the port should be tuned at 34hz. it came to 1.45cuft per side with 10.5X1X14.21 for the port for each sub. this leaving me with a 2inch port in the middle of the box. again i think i did that right, if not please correct me.
for the hdc3 10 i came up with 2.76cuft after displacements with a slot port tuned to 34hz at 10.5X3X21.97.
if i did that right, which of the 2 do you think would sound better. the amp i intend to run for either set up is a 1250.1.
