Aeroports or slots?

[pro-rabbit 5,000+ posts]

I like areo's in boxes but it would be nice to know how big he can go. If he has like 8ft of useable space he could go very big with the aeros.

He he has the space available, I would just go with slot port in most cases. He will likely have an issue with the port length if he goes with a large amount of port area. That has always been a huge issue with them. Most enclosures are never more then 15-20 deep so that is rather limiting in port length.

for refrence im using a 3" aero for my 8" sub. 18mm Xmax, ~400W of power... 1.1 cubes with a 14" long aero

He could fit longer ports if he went ports side sub back and did like a 16-20" deep box couldn't he. Something like 20"d x 35"w x ?(h). Of course you need to remember I'm not a designer lol. I guess it all depends on the area he has to work with and the desired results.

It is possible if he has the room for a side port.

I have max dimensions of: 35" wide, 13" tall, and 18" deep. And i do want 3.0ft^3 @ 30Hz. I'm open to whatever designs would work, ex: single chamber, aeros, separate chambers, etc.

And i have 850w rms to each sub. If that matters...

you have 3.68 cubes to work with. using a single 6" aero 22" long will net you 3.09 cubes for your subs and give you 30.55hz tuning. add in the aero flares and you should be at or just below 30hz.

Is the 35" total width or does that leave room on the sides? If it leaves room then how much?

 

[mat3833 10+ year member]

oh, and i used .2 cubes as sub displacment. forgot to take into account bracing. so you may end up with slightly less than 3 cubes and have to add an inch to the aero. but im sure someone will factor all that in.

I am using a "flared port" (Precision Port) in my setup. I was thinking about using slots but for my enclosure, a flared port worked due to size restriction.

 

[N9ne Millahhh 10+ year member]

Yeah i'm gonna use Precision Port too for my application, if that's what i end up deciding.

Matt, My sub displacement is 0.14. is that for the single chamber and port on the side running the long way? did you use torres?

I was hoping to get port and subs facing back, unless it wont make a difference?

Omega, The 35" is total, because i need to fit it in my trunk....lol so there is room on the sides for sure but not enough to actually build with.

is this the design you were tellin me Matt? i don't know if i got all the numbers you used plugged in but it's close. is there any way to do a single box with two separate chambers?

yea i used torres. subs back port side. single chamber for seperate chamber just cut your width in half and use that measurement. give me a sec and ill figure it.

i dont see how you can use an aero if you want seperate chambers. usnig a 4" aero you need like 20" of port length. yu could make it an "L" aero, but id just make it one enclosure and use a 6" aero.

Matt

EDIT, im guessing the sub displacment is .14 PER sub?

Matt

 

[N9ne Millahhh 10+ year member]

yessir. 0.14 displ. per sub.

is it still gonna be as loud as if i had slots firing back?
