another Infinity 1262w build
i have had two of these drivers in two 1.5cft. sealed boxes for a while now but i want to try them in ported enclosures.
i know these have been modeled and built to death but im new to using WinISD and all my other builds were copies of others designs so i wanted to model these myself so i can get better at that part of DIY.
my plan is to build two slot ported boxes:
4 cft. NET volume after accounting for the port, driver and bracing.
Two ports 4.5" wide 1.5" tall and 25.8" long
box outer dimensions are 18" wide 26" high 21" deep.
port volume at 435 cubic inches
bracing at 200 cubic inches (plywood strips)
driver at .12 cubic feet
i come up with a max rear port velocity of 24.97 m/s at 17.87Hz.
SPL with 300 watts is just over 104 DB at 18Hz. HPF at 17Hz.
