JR Yonts Posted January 8, 2017 Report Share Posted January 8, 2017 Would a 1:1 port ratio sound better than a 1:4 for 2 sa 10's? Link to comment Share on other sites More sharing options...

ShadeTreeMechanic Posted January 8, 2017 Report Share Posted January 8, 2017 The port area is too small on the middle one. As far as the shape, I'm not sure if they would sound any different. The square port might be more efficient I don't know. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted January 9, 2017 Report Share Posted January 9, 2017 What vehicle is this going in and what amp are you going to be running? Input power is going to be a big factor is how much port area you need. 3 common wall slot ports are the easiest to build and help strengthen the box. As long the port aspect ratio won't be over 1:5 that would be my suggestion.

I was just wondering if a square port would sound better than a rectangular port. The box is going to be similar to this..... Link to comment Share on other sites More sharing options...

As long as the port is sufficiently sized and the aspect ratio doesn't get above 1:5, they are all going to sound the same.

Trit, when you exceed that aspect ratio, are you more likely to have port noise/chuffing? Curious why that ratio is important.

Curious why that ratio is important. Yeah port noise/chuffing is part of the reason. High aspect ratio ports have a higher amount of internal surface area than a lower aspect ratio port does. This increases air resistance which can lead to port noise along with port compression. Its bad.
