external aero port

[ToNasty]

im experimenting with enclosures since i have time off work. the next one im going to try is a external aero port. if i need my box at about 2 cubes, how do i go about doing the external aero. thanks

try using bass box pro makes things pretty easy

If you need a 2 cube box net. Then build a 2.1-2.2 cube box(depending on the woofer displacement).

External aero ports don't take up any space inside of the box, obviously.

see i thought that since it was attached to the box that the port was also part of the box volumne

nop, it doesn´t take any room if it´s completly external, external aeroports are the best thing out there lol, you can change port area, re-tune, etc etc and its always a fair comparisson since the internal volume of the box is not changing any, my last box was for a single loudforce 85 series 12" on a loudforce 2K wired at 1 ohm, single battery on front, i was burping a 147.1 @ 46 hz and also played amazing on music, i installed that box in a trunk with a DD m1b just for fun and the car was doing a 144.5 @ 45 hz, here´s a video of that box

so what diameter port would be sufficient for me. its actually about 1.9 cubes after dsplacment and its an sa12

[fecupe2001]

Depends on your goal, my 85 series love bigger ports, while the 80 series loves smaller ports for music and bigger ports for spl, the SA its definitely a great sub, but im pretty sure that a single 6" aeroport would give you a "peaky" box, with 1.9 cubic feet and a full lenght aeroport you could end up tuned around 38 hz and a higher peak, bandwith would be kind of small, if you love to play loud only from like 37 to 47 hz then a single 6" aero would work AWESOME with a great output, if you are looking for a flat respond and more SQ then a single 4" aeroport would work just fine, if i were you, i would start with a 4" aeroport , test, re-tune, etc etc, and if you are satisfied then get a 6" aero, i LOVE how the box on the video sounds, yes is a smaller bandwith but i didn´t want to play any salsa or trance music lol

[ToNasty]

im more sq than anuthing. and i listen to a variety of music. so i guess ill start with a 4" port.

[fecupe2001]

yeah, single 4" aeroport would sound very nice on music, you can use pvc and flare it, but for the price of a PSP i guess i would get that one, definitely need some sexy nice flares to eliminate any port noise...

Gonna give you some advice. I don't understand people who have 1 12 and wnt to tune to 25hz because they like "lows".

You're not going to get massive lows with a single 12 on 1k lol.

So I advise you to do what fecupe said and do a full length 6" port. So you can at least have a loud 12 in the high 30- mid 40hz range. People will be surprised.
