This may be a daft question but I'm going to ask it anyway -
If you have a design for a woofer in an aperiodic box and then double the box size and add another woofer does the aperiodic vent work like a normal vent i.e. you just double the area (or have two of them) keeping the length the same (i.e. the thickness of the box wall) ? Plus within reason can I assume the vent shape is immaterial so long as the area is kept constant ?
By way of an example, take the Seas A26 - 28l volume with aperiodic vent 30mmx220mmx19mm (wood depth) with 12g of stuffing. If I use 2 woofers in a 56l box can I use either two ports the same dimensions or a single port 60mmx220mmx19mm (again keeping the filling density the same, 12g>24g).
Sorry, this may be basic but just wanting to understand how this works.

Yes that should work. Do note that the A25/A26 (like the Jordan ARU./ScanSpeak VarioVent) is the cheapest/poorest way to work toward aperiodicity.

Dave, many thanks, just wasn’t sure if they acted like a stick port. You suggest cutting a hole in the cabinet and adding stuffing is not the optimal way to creat an aperiodic vent. Would you like to share a better way and how one would go calculating the dimension/stuffing regime. Just here to learn.
