I am hoping someone can explain bandpass and how the port tuning works.
I recently had a friend give me a bandpass box with a kicker cvr 12d2 in it...
the box measures 15"h 20"w 8. 5"d both sealed and ported side having these measurements. 2 tube ports 3.875" What i don't understand is way it sounds for the ports it has???
According to every port calculator iv used its tuned at 95hz! Am i measuring port frequency wrong or does bandpass create a different port frequency that is measured differently.
Also can someone explain bandpass and how you tune one.
I AM ASKING, CAUSE THIS BOX SOUNDS AMAZING DESPITE THIS QUESTIONABLE PORT FREQUENCY!
Im building a subwoofer enclosure for 2 12' type r subs (2kRMS) and wanted to know what size enclosure i should use. I have depth of 17 height of 15 and width of 35 max.
I was thinking around 5.5 cubes
I want to tune the box to around 32 hertz and want very low bass.
What diffrence does a larger enclosure make over a smaller one?
Also how big should i have my port i will be using a slot port but wanted to know if a port which its height is less and width is more is better than a port with a larger hight and smaller width. I was thinking a 4' wide and around 9 heigh is thw width fine?
All help appreciated
Ok so i have seen many different answers on this and I am wondering on what is the correct answer. so my head unit is a pioneer FHX-520ui
now on the head unit there is a bass Level, not bass boost but bass level it goes from -24 to + 6 its default setting is 0 when i am DD-1 tuning my set up should i set this at 0 or+ 6 or somewhere in between, i'm assuming this is Gain from the rca outputs, and if it does not matter what are the beniffits of tuning at 0 or +6 i just want to tune it for the best possible output, what i am currently running is in my signature as well, I also plan on upgrading to an AVH deck with 4v pream outputs because i feel like i can get better bass response out of these subs.

I've been mainly a lurker in the audio world and figured maybe I'll finally do a build thread to show my Daily Driver. Here is my 2002 Mitsubishi Galant. Being a college student I don't really have the money to go totally all out with audio, but I do what I can haha. All pictures can be found below.

This car has come a long way since the first set of shitty 10"s, then 2 15" kicker CVRs. Its still not done, I.E. It still need the interior of the trunk put in and the subs box still needs a little facelift, but Im happy with the overall sound quality of the build. I'm hoping for 145+ dB but am not sure if im quite there. I'll get metered sooner or later and I'll post up my results. I have another build with a 1990 Civic Hatch on plate for the next semester. I've started a car audio club/ team at Virginia Tech and that will be our demo car for the spring. Thanks guys for the look and I look forward to try and be more active here and other audio forums.
