Square port vs. Round port

[king ranch 5,000+ posts]

In the last year I have had no less than 10 boxes that I and the DFW crew have built. I will never do another slot port EVER

why

I thought port velocity was dependent on port area.

Umm NO!

how do you flare the pvc and is there any difference in using pvc compared to psp ports

 

[bigbirney420 10+ year member]

why

Not as efficient, more port noise, and bigger overall boxes

Why is that? port noise? Tuning issues? Please enlighten me...

what would u recomend for 2 12's l7's for net vol and what tune and what size port and how many

consider they are on a kicker zx1500

I always use box notes and winISD.

Kicker recommends slot ports.

Sometimes I use this. http://www.subwoofertools.com/forum/ported-box.asp

The x-mas determines the port width for that calculator.

yes it does. a round port has the best perimeter vs. area ratio.

Which means nothing in a daily box.

aero's are way more efficent

True I should have stated regular pvc.

[king ranch 5,000+ posts]

and that makes no sense u said aeros have less port noise and sound better

This will be install dependent. Also you wont use as much area for an aero port as you will a slot port.

If you have a round port box build correctly and a slot port box built correctly (note not necessarily the same port area if using areos) you will be hard pressed to hear a difference.
