Ok members, i need help ... i am surveying around some 3" ports for my 12" subwoofer project for home use (target f3 = 30Hz which was close to the Fs of the Driver) box will be about 60L (not inclusive of Driver and port) ...

As a result ... i came across these ... (1) Standard Flared Port (2) Dimpled Flared Port (3) Aeroport

What are the difference of these 3 ... ? Does the Dimpled flared port and Aeroport offers better performance (in terms of port noise handling / chuffing) compared to the standard ones? if yes the difference is significant or not? Assuming all of them have same length, flare radius and diameter. Each with sample photos

Because of the cost of each different so much ... i need to make sure i get the correct ones for my application ... TQ
