I'd much rather use a single 8" port than try to mickey mouse with a bunch of smaller ones, particularly if they're going to be crowded together.

I think you'll be OK with 8" flared port per sub. Won't be optimum but by the time you had port turbulence you'd never notice because they'd be so loud, and when you're really pushing on the small side I find box volume > port area particularly for daily/music.

Nice sub's, box size and what are you going to tune it to?

I was leaning that way HIGHSPLS. After many hours of research what is pushing me towards the multiple four inch ports is that is whats modeled on the TC SOUNDS enclosure recommendation. They have two sealed enclosures, three vented, and a couple PR set ups modeled. All vented enclosures use 4" ports as there baseline.

Funny thing is, before I read that on there website, I built a 4 cube sealed box, listened to it for a day or two, then decided to port it. I threw together four 4" inch ports and tuned it to 32 hz. That box sounded good! I was figuring if I added 12.5 more inches of port area with another port and also added a cube it would all sound even better. With my space constraint I really do not have enough unloading room or space for a single large port anyway. I think the multiple fours are gonna work better for me.

Obviously I have no issue building and trying boxes......so, if I build this box with five 4" ports and don't like it, I will just try another! I CAN NOT imagine having to pay someone to do all this for me! That would def price me out of the game!

SIlver n black, thanks man! Are you referring to T line box in pics or new box I am getting ready to build? New box will be 10 cubes after subs, ports, and bracing. Tuning 30hz.

Adding two runs of 3/0

The right tool for the job!

I was referring to dual setup so 10cf? Reason was asking is i'm also going to run 2 18's TC5400. Just having a hard time on finding information, I have around 19cf.

Yes, ten cubes after sub port and bracing disp. It is on the small side but you can go even smaller. Going to tune to 29 or 30.

Are you using precision ports? I have a shameless sale plug if you are.

No worries bud.

And the plug: I have 3x new dimpled 4" precision port kits sitting here that I'd like to sell.
