What'll Be Louder

[dbwesz]

hello i've a question.

what will be louder.

an big round aeroport or an square port same inches etc etc and same freq.

i've an 18 cub box..2 MT 18's and 4 t30001bd's

my port at this moment is like the build in size of an 18' SX im using that hole as an port an maked it a lil deeper but is not loud enough on music.

will it be better if i make from that hole an square port ??

[dleccord]

hard to say. only way to know is to try. some will say aeros over slotted/squared ports, vice versa.

if that aint loud enough on music, try a different tuning, possibly a lower one. also, it might be easy if you build those boxes with removable ports.

i honestly dont think there would be a diff in spl. i guess its worth a shot though, you could try it.

SUPPOSEDLY you can gain 3 db by going areo. But I don't know how true that is.

[Slinky]

im glad you put the SUPPOSEDLY there cause that is def not true.

i highly doubt a 3db gain by switching to aeros. i have heard that aeros are more effiecient with the flow of air, so maybe a tenth, or a few tenths at the most...if any gain at all. but try it, maybe u will suprise us all.

yeah, 3 db is a lot of diff. it takes twice the power to gain 3 db. your not gonna gain 3 dbs just by an aero port.

SUPPOSEDLY you can gain 3 db by going areo. But I don't know how true that is.

depends on the application, I have heard of people getting louder with areo's, then slot ports, or squared ports.

it's really hard to tell you what will be louder in your application, you have a wall correct? I only know of a few people that have used round ports in a wall, I tried round 2 6" round ports in my first wall, I didnt care for it, they werent areo's though.

its gonna be a test and tune type of deal, build, tune test, retunes test agian.

goodluck, keep us informed on your project.

i would def like to see how it goes though. i could be wrong here so i would like to see you try it.

keep us informed.

thnx for all the info..

but i forgot to tell its already tuned LOW like 34 hz port freq and 44 hz car freq

i wanna tune the square port to 27 hz or an aero port to 27 hz but a want a lot of air moving what will be the best then and maybe the loudest ??
