Alpines website suggests .75-1.75 per sub. I will be building a box soon for one 12'' tuned to 32-33 hz. They give these dimensons (external) for each sub 18x13.5x16.5 that will leave you with 1.7 cubic ft after vent and sub displacement. You can always use the box calculator on Reaudio.com. If...

Ride what? A motorcycle of sorts? I can barely walk sometimes.

It's important if you want the box tuned to a certain Hz. Use this to figure out the port length. LV= [(1.463 x 10^7 x R^2) / (Fb^2 x Vb)] - 1.463xR Fb - is the desired tuning frequency of your enclosure in Hertz. Lv - is the length of your port in inches. R - is the inside radius of your...

Good to see another CT fella. I'm in the same boat new to this site, I'm about 5 days old now. West Haven

Ascitiesburn, I have the same situation as you. Same sub and I want the same size box with around 33hz. I used RA also, did you calculate the box then subtract the sub displacement after you did all the calculations? I noticed there is no spot to plug in the subwoofer displacement. I personally...

Hey I stumbled upon this website during my internet journey. Reaudio.com I used the calculator on the site and got different numbers but not by much. Just wondering if anyone has used this and if it worked out good for them?

That .75 is the thickness of the mdf not the port. The port will be 2'' x 28.8''. The measurement of 28.8 x .75 x 14.5 is the vent wall that will be in the shape of an L.

Just signed up. Some nice setups and advice here.

I figured out the box size I think. I came up with roughly (internal) 21.25x13.75x14.5 = 2.2. I then subtracted the sub displacement .071 and got 2.1 cubic ft rounded off. I figured out the slotted port length at 28.8'' at 33hz tuned To get the vent displacement I did as follows-...

I have a 12'' Alpine type r, swr-1242d dvc sub. Alpines website suggested .75-1.75 cubic ft box for a slotted port at 33hz tuned. They gave these external dimensions 18x13.5x16.5 and after vent and sub displacement the internal gross volume would be 1.7 cubic ft. The vent length they give is...
