Re: Dual Alpine SWR-1242D Ported Box Help
the box looks good but i wouldn't use re, you have to look at the total port length, not port length 1 and 2 they only add to 18.75 which would tune your box way higher than 32, im not on my computer to go on winisd to check if its accurate, but i would make sure the total port lenght is 24 when you make that box so you keep that 32hz, i use to own those subs, and i had a box around that size it was 4.4ft^3 at 32 but take away sub displacement and it was around 4cubes.
it sounded pretty good too.
carpeting does nothing more than make the box look better it doesn't change the sound or anything.
