Hey guys,
Im looking for a set of box specs/plans/cut-out sheet for a ported box.
Subs are Audioque HDC3 15" Dual-1 Aluminum coils. Ill be using (2) 6" Precision Ports for the box. The box wont be fancy, just a straight foward
rectangular box with subs facing upwards at the hatch and ports firing to the rear.
Thing is, I dont know if I really have enough internal box space for these.
Outside diameters that I have to work with are: 15.75"H (.75 for the second baffle) 34"W X 32" D.
Looking at 36 or 38Hz for tuning

Would I be able to pull it off?

thx!

If your going to use them ports I'd use 3 cut to 20.75" Double flared. If you use your max dimensions you'll have just over 6cubes.

20.125" if only flared on the outside.

You might want to think about only one 18" or one 15" in a large enclosure with more port area. What amp are you going to power these with?

Flares for the ports. Either on both ends or just the side the exits the enclosure.

Audioque states you can use the 15s from 3-4.5cu.ft net. You have 7.75 to work with. so it could be tight with the ports, you may have to have them half internally and half externally the box.

So, with the dimensions I have and those ports, its almost impossible?
I thought by buying those types of ports that it would help on air space over using a slotted port. I read they are more efficient that way

Make the enclosure 6.75 cubic feet after sub and port displacement.

Then make sure each port if 13" in length.

You'll be tuned at 36hz

I forgot to add that each port, if cut to a length of 13", had a displacement of .2 cubic feet.
