BeachJoshua Posted June 13, 2010 Report Share Posted June 13, 2010 1st. What's the big difference between PVC and Aero? 2nd. Whats the big difference between using a HUGE port like the ones where you can fit a kid in, and smaller port that you could fit like a house phone in... 3rd. Aero Squaro etc... Rounded edges with ports, why? What does it do? Basically, all the info I can get on ports...

bobonit Posted June 14, 2010 Report Share Posted June 14, 2010 I can answer number 1, the Aero comes with pre-made flares, pvc does not have flares. Without the flares, you can get turbulence and port noise. However, you can make flares for pvc, its just extra work. I'll take a stab at number 2, I know that if you make the port too small, you will get port noise, like a whooshing sound as the air travels in and out of the port. As the port gets bigger, that noise goes away. But I'm pretty sure, as the port gets bigger, you get a narrower response (more of a peak), where as a smaller port can give you a flatter response (less of a peak). Rounding the ends of a square port does the same as having flares on your aero/pvc ports. It reduces port turbulence and noise.

n8ball2013 Posted June 14, 2010 Report Share Posted June 14, 2010 aero ports are preformed and bought. you see people using pvc as a cheaper alternative. PVC may also induce port noise depending on install. 2 it has to do with port area. a larger box typically shou;ld have more port area. the squareo port as you call it has the ends rounded for increased air flow. it can be done a multitude of ways. kerf cuts is one way.

So if I use a router and round off where I put a PVC for a port, it will be an aero? aero ports are preformed and bought. you see people using pvc as a cheaper alternative.

What is a kerf cut? boxs with those huge ports are fart boxs aka burp boxs. Designed to play a certain freq. loud as hell So like those people running 2 12's in a CRX with multiple big ass aeros coming out of it.
