I bought a couple of 3" x 11" flared ports from parts express on buyout. They are basically precision ports that can't be adjusted.
Flared Port Tube 3" ID x 11" L with 5" Flared Ends
Anyways, I was wondering if a pair of these ports would work for my sub setup. I plan to do a 2.75 cubic ft box tuned at 34 hz for my PG Ti Elite12d. These ports give me that tuning frequency if I use both. I'm just wondering if they will be enough port area. This sub has 3 inches of excursion. If these won't work I will just go with a slot port.
