I want to build a box that will be 1.5 Cu FT

I’m lost on how to figure out how big the port should be want it to tuned to 35hrts

Is they a good site that can tell me how to figure the port size, and that Could tell me if the measurements I have would make it to be 1.5 C.U Ft

Also What is the equivalent measurement to 1 C.U FT

Thanks looks like everything has to be 15" to get the 1.5 I need ofcouse one wall will be slated so its not a a complete square box

But I still haven't found out what size the slotted port needs to be

Any help on how big the port should be

thanks for those links

What is the equivalent measurement to 1 C.U FT ie how many cm

Ok, there are roughly 2.5 cm per inch. so 12 inches would be 30.5 cm .now for inside dimension they would be 30.5 x 30.5 x 30.5. Outside dimensions would be about 32.5 x 32.5 x 32.5. That allows for the thickness of the MDF, that is if you use 3/4 in. MDF. Also, for the port, do you want it to be a slot port, or do you want to use a round port?

What sub are you using, and are there any size limitations of the area the box is going in.

with only 1.5 cu ft you are better off using a 3" piece of pvc about 8" long.
