Q-Logic subwoofer question

[wulff]

I bought a Q-Logic Model: QLH-1.2512 (this is the inclosure that allows you to use it as a sealed or a ported sub).

Anyway, on the inside where the vent enters the middle slot the edge of the wall (where the slot is in the box area) I noticed the edge has sharp edges. I have always known that in a vented box with round ports they should be rounded off on the inside to prevent noise, does this hold true for rectangle ports? I was going to round them off but thought I would check to see if anyone has any information on how the inside rectangle port should be finished off.

if it gives you a noise problem, if you are really bothered by it, round it off and see what it does

when i build boxes for home use, i put a curved triangular piece in the corner of the slot vent to get rid of a lot of the noise.
