Box build check please.

Hello all.

I built a box for a 15in according to re box calculator.

The measurements are 36in wide x 16in high x 20in deep with a 3.5in port width at the front. The length I'm playing with at the moment but can you check for me what precise size this box is giving me and what tuning frequency as I want tuning to be around 28hz or so.

I haven't included the sub displacement either

Thanks

you'll need 34 inches of length to get to 28hz at 4.15 cubes . I'm putting 0.13 as your sub displacement. Havent accounted for any double baffles or bracing yet so you can do 35 length and add some bracing and get close to 4 cubic feet at 28ish hz.

Thanks for reply.

So that means the length of port running inside the box along the wall ? Is that correct ?

take a look at these designs, its the red line aka port length, not the port wall aka wooden pieces. You should be able to figure out how to calculate it after looking through the designs and reverse engineer the results.

what woofer is it?

50in^2 is low for a high displacement driver.

which driver is it? i came up with the port being 36 long using the given dimensions.. i personally think that is too low though man
