Hello Wizards, I wanted to pick some brains (whichever are willing) and get an opinion on what I plan on doing to tell me if this is the correct way to go about it. Gear Old Sundown Zv3 magnet, New Sundown Zv4 Basket and soft parts (DVC 1ohm, plan on running at .5ohm), CAB 1600.1 (run @ .5ohm), and a 6th Order Bandpass I have designed and plan on building. 6th Order Design: 3/4" Plywood, Double Baffle Sub Wall Magnet Side: 3cbft, 30Hz, 1 Aeroport 4.5" diameter x 12.51" length Flared both sides Cone Side: 1.5cbft, 50Hz, 1 Aeroport 4.5" diameter x 8.09" length Flared both sides I am using WINisd to play around with box and port sizes and I really like the transfer function this design is providing. I have measured the size of my woofer accurately but have used the baseline testing of a Zv4 12" as the Woofer data into WINisd (should I not do this?). Of course this doesn't account for port displacement, woofer displacement, and bracing but I will optimize the box shape and size to make sure I end up with the cbft stated above on each side of the sub woofer. Do the Aeroport sizes/design sound stupid? Does the cbft Ratio sound weird? Does the HZ Ratio sound stupid? Should I trust WINisd? Is there anything I should keep in mind or watch out for? All comments are welcome, thank you for the knowledge.

So i made an earlier thread and decided to just make a single larger aeroport. originally it was a puny 4" with a shit rigged set up. so i went to Lowes and picked up a 2' tube of 6" PVC pipe and here's the difference. now the green PVC is just the left over pipe and the rest is of course installed. i had a 40"x16"x16" box, and a gross with displacement an overall ~4.5ft^3 box. now with that puny 4" this called for a 4"x~4.5"(35Hz) aeroport. this was horrendous with port noise and low output. i changed out to the 6" which called for a 6"x~14.5"(32Hz) aeroport and it made a world of difference. it was much louder on lower volumes, and before i could only feel the bass in my hands when they were vibrating with the rest of the car. with the 6", i can literally feel my throat caving in(not really) and my ears having sharp pain. now this was just a box upgrade(doing the Big 3 upgrade with 0AWG and a Kinetik HC1800) but it was felt almost twice as loud!!
