I'm going to build my next box, and i'll be useing 4" areo ports. I haven't gotten the ports yet, but I need to know if they will fit into a 4" PVC elbow? Do anyone know if this will work/fit??

parts express now sells 'kits' with elbows and stuff.... i don't remember if it's the 4 or the smaller stuff though.

They have a 4" kit with bends, and straights but the 4" flared kit will not work with 4" PVC from what I've heard; They have different diameters...

Thats what I saw looking at them on partsexpress' site. Their male to female, so I wouldn't be able to attach the other end of the port to it. This is why I was asking if PVC elbows would work. If not, then i'll have to put the ports at the other end (oppisite of subs). :cool:

Kind of a rough idea of what i'm looking at doing.

Why not do a single 6" at the side?

The elbows fit for me in the past....

4 inch PVC will mate up to precision ports...you just have to do a little sanding and work with it for a while to get the flares and the coupling rings over the pipe.

^ If you bought precision ports they are held together by a ring on each in. They suggest cutting it to what ever freq you want and glue it. I suggest using wide electrical tape so that you can always retune when ever you change boxes.

I'd do atleast 3 areo's. Your box is going to be over 4 cubes and the 4" are only ~12.5sq.in. of port. So 4 4" areos would probably be best.

EDIT: My math was off...forgot displacement amd wood. Probly ~3.4 cubes. 3 4" will work fine 2 would be ok, but not the best.

Ok, but I was told by "mrogowski" that they would be good with 24sq. in. of port. What would you suggest?

They are his subs...

but IMO you size the port to the box, not the sub.

14-18sq.in. per cube is a good rule of thumb that I try to stick with.

Your box is ~3.5 before sub and port displacement.

How does one compensate for the difference between PVC & areo ports when calculating the lenths? There is a difference right??

The calculator on psp-inc will tell you the lenths of a flared port or a strait one. Its usually ~1" difference.

I think the Aero's are 1" longer...
