Going to try to build my first box ive ever built lol.
Gonna be a daily setup thats does good db numbers on music

My dimensions:
Aq hdc3 18
18"Hx
33"Wx
20"Dx
comes to 6.87cubes(before sub displacement)
1-8" sonotube aeroport tune it 40-42hz(have not decided on tune or lenth)
sub up port back,
port on driver side,
sub on opposite side of box from port (passenger)

but curious. i see alot of ppl using these sonotubes but dont "flare" the ends of the tubes.
i tried to look through the search but found no info or reason. anyone know why they dont
flare these?

How much power? Pro-rabbit was telling me AQ's like huge boxes on reasonable power. so if you're running 1000-1500, you could probably bump that up to 7 cubes after all displacement. If you're running higher power though 2k-2.5k he recommended 6.5 as a MAX

yea ima be running 2k-2.5k. so my total for cubes is 6.87 before sub. so after im figure about 6.5 give or take

are you set on the 8" sono tube? Cuz you get a bit more port area and flared ports on the aero's

Pro Rabbit is right, and you'll find that the suspension is the main determining factor in how much volume each woofer prefers. The smaller/stiffer the suspension, the more volume the woofer will need.

so should i start with 7cu before sub displacement instead of 6.87(before sub)?

I'm guessing you have the aluminum coil since your gonna throw 2.5+ at it?

You can throw 2.5k on the copper coils, you just have to be careful, it's what I'm planning on doing, and it's what dozens of other people have done too, no biggie.

.13 is not going to change it one way or the other. Your closed fist probably displaces more than that.

I would shoot for 6.5 cubes net and while you asked my opinion, I would not use an aero unless it was flared. There is NO benefit to it without.

The terms NET and GROSS are used all the time so I'll define them because you'll need them throughout your life. GROSS = Total amount with no deductions factored in.
NET = Total amount after all deductions are factored in. So let's say you get your pay stub and you make 10 dollars an hour and worked 40 hours that week. You GROSS 400 dollars a week. After all deductions etc you might be left over with right around 300 dollars NET.
So in this case, NET would mean after port displacement, after the wood displacement, and after speaker displacement and any bracing etc.

Cutting corners already best of luck to you.

Yeah I have to agree. I've seen a lot of people try to make their own aeros and people rarely get it right the first time.

not really cutting corners. someone brought them to my attention and i thought they looked kinda cool, and pretty easy to do. i havnt started building yet. just getting info. i wouldnt have started a new thread but i cant find the last couple that i started for some reason
so i figured i would ask about them.

i didnt know this til just like 5 mins ago. he has a 10" flared aeroport in his garage that he forgot about.
he said i could have it for free. would a 10" be to much for 1 18?

and this is a actual 10" aeroport, not sonotube

ok. i found a guy and i got a 8" flared aeroport how exactly do i tune this? or calc the port area or watever

When tuning a "flared port" you have know how they are flaring and all the dims of the flare. Other wise it is just a guessing game to what you will be tuned to.
