Ported or sealed box?

Recommended Posts

I am wondering if I should make a ported or sealed sub box? I would be getting one or two 10" Kicker CompVR and I mostly listen to rock music. I would also be basing my amp off the recommended power so power is not an issue.

Also would using 1" MDF be better that 3/4" for the outside of the box?

You'd want a bit more power than needed for headroom especially with rock music.  You wont see any audible differences going 1" instead of 3/4, Those kickers do not produce the amount of sound pressure needed to warrant extra strong reinforcement. If you dont know how to design a proper ported, go sealed. Or if you are willing to learn or have someone do a design for you, then definitely go ported. A bit smaller and medium low tuned is decent for rock music.

In the manual there is a recommend design for ported

Before I get two deep into this is there another sub you would recommend around $100

Does the box volume not include the volume of the vent in WinISD? I can't find the answer anywhere else.

Say I had a 2ft^3 box and my vent is 2x10x20 (0.23ft^3) (pretend the vent walls are paper thin for simplicity) the total internal volume of the box would have to be 2.23ft^3, or does it include the vent?

After messing around this is what I got (Red) over recommended (Black). Should I try and move the dB bump to the left or right?

In the design you need to add the vent afterwards. The internal volume will be much higher. So you want to design the box to get a 2 cubic feet net volume first after accounting for bracing and subwoofer displacement then add on the port afterwards for proper tuning.

Red will be smoother overall and play deeper which will be better for a wider variety of genres. Black will hit a bit harder, less overall sound quality but definitely punchier.

So the volume of the box on WinISD is 2 cubic feet and I would need to compensate for the size of the sub, braces, and port to get a box size closer two 3 cubic feet.

yup basically.   If you want to skip all that, download torres box calculator, it includes all displacements in its formula for you.
