2x12" Dcons in 3.8 net. 500-600rms.

Want advice on whether or not 2x3" PSP Aeros will suffice or if 2x4" should be considered necessary.

Thanks.

A pair of 3" aeros should do the job.

I would go withthe 2x4" ports. I have a 3" aero on my single 8" and it has port noise.

2 3" aero's should do but personally I'd use a single 6".

Yeah I want to use a single 6, but it'd look like a chimney because the length required is longer than the box has room for...Plus they're $40 whereas the others are ~$10 ea.

Not sure how I feel about having a chimney....

Looks like I'll go 2x4" or 1x6" but i'll be stuck with chimneys...(external sections...) not very clean looking...want a better option if I can find one.

what are the dimensions you're working with? what are you tuning too?

Subs back, port(s) up.

16"height external, 14.5"height internal. Tuning 30hz.

Box is 16h x 17d x 39w with an amp rack alcove that takes up 16h x 4d x 22w on the rear,right side.

Purple area is empty space for amps. grey circle is for port(s)

why not tune to 34-35hz and get a higher db gain and be able to fit a 6" aero port. you a not losing much if anything by tuning 4-5 db higher.

4-5hz higher can make a pretty big difference in the low end.

True, though trying not to spend on ~$100 on port pieces lol.

Yeah. ~32 would be the highest I'd want to go with these, and that's pushing it. Though can't argue with db gain.

i would go with two four inch ports i used to psp in a recent set up for two type rs 4.0 cubic feet tuned to 32 hz and it performs flawlessly. i would not advise the 3 inch ports over the four.
