Goblenator Posted October 11, 2017 Report Share Posted October 11, 2017 Ok I have two V1 Fi Audio Ib3 15's and I have an idea. I'm gonna build a 4th order for them and my box designs map out really well on a response graph but i've never built a 4th order bandpass before. the port i will be using is a "Bigassports" 10" aero port. Will that be enough port? Port chamber will be 2 cubes with polyfil Link to comment Share on other sites More sharing options...
06RTCharger Posted October 11, 2017 Report Share Posted October 11, 2017 A single 10" aero gives u a port area of about 78.5square inches. Is that all u need for two 15s? Link to comment Share on other sites More sharing options...

Triticum Agricolam Posted October 11, 2017 Report Share Posted October 11, 2017 How much power are you going to be running? Whats your ported chamber tuning frequency? You don't want to put polyfil in your ported chamber. Putting it in the sealed chamber/s is fine.

Goblenator Posted October 11, 2017 Author Report Share Posted October 11, 2017 Will this be enough port to not have port noise? Aero's are more efficient so i'm hoping this is enough cause there isn't room for more port. Link to comment Share on other sites More sharing options...

Triticum Agricolam Posted October 11, 2017 Report Share Posted October 11, 2017 Your 10" port should be more than enough.
