[oxsign 5,000+ posts]

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). //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Why not do a single 6" at the side?

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.
