Using ports that arent flared...

If I put a straight piece of pvc as my port what will happen? I see everyone talking about aeroports and flared ends.

It will "work" just sand the edge to make them smooth.

I have done it on a box for 2 15's. I used (4) ports out of the bottom and it worked well.

no flare = port turbulence = distortion = ****

Would a normal slot or tubes with no flares be better?

That is a bit of a generality. I've heard plenty of home audio subs that didn't have a flared port and had no port noise. Port noise is a actor of port area and the ammount of air moving in and out of the port. A nice big flare will reduce turbulence and the likelyhood of noise in a marginally sized port. If the port is large enough for the sub and the power going to it, there is no real need for a flare. Break the hard edges and you should be good.

I have two 4 inch ports in a 3 ft^3 enclosure. The driver is a 15" rl-p. Should I look into some flared ports?
