How Many 4" Aero Ports for single HDC315 sub??

OK, for now I just ordered three, I actually have the room to go with 4 but I will try three first, I can always add one later if I think it needs it, right?

For a daily driving box, I would do 3 4's. 2 6's is too much, IMO.

The beauty of aeroports is you can put as many as you like on there and just plug one or more to try out different amounts of port area/different tuning frequencies.

if your building a box that is 4 cubes you will only need prolly 4 aero's at 12in to be at 43hz or higher, 3 will put you at 38 or somewhere in there. like i said before i have a 2 cube box with one 15 using 2 4' aero's tuned to 42 the ports are 12in each. they are fun to use but remeber on your cutout you will need to cut out 6in for them to fit right an might i add use a rubber plumbers cement an some duck tape to cover up the sides for a airtight seal. but i will be on the lookout for your build log hit me up if you need some help

6in for them to fit right

An easier way is to just trace the small 4" flare and use it for the cutout

Thanks all for the help! I really appreciate it, I have built a few slot port boxes (about6) but this is my first set of Aeros to be used so I am looking forward to how smooth they should sound!

also i see where you guys say keep the port 4" from the walls but how about the sub magnet

Depends on what you can properly fit.
For single 15's the popular combinations are:

1 - 6"

3 - 4"

4 - 4"

I haven't seen anyone do 2 6's yet for a single 15, I've been wanting to try it myself.

i did an 8.5" sono for a 15 but it wasnt flared very well //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
