What is the Size and Tuning of my box?

[Naledge503 0]

If anyone can help me, it would be greatly appreciated. I had somebody build me a box for my (2) 15" Q's but I think the Tuning is off. Can you tell me the Size and tuning of it? here are the dimensions.

The box is: 35"x25"x25"

The port is: 29"x23.5"x5.5"

Thank you!

How can the port be 25.5"x23.5"x29"? If this is a slot port then how wide and high is the port and then how long is it? Did you mean the port is 25.5 high by 3.5 wide by 29 inches long?

The internal box size minus the port is 8.5 cubic feet asuming 3/4 inch material. If the length of the port is 29 inches then it's tuned to 33hz.

Say mike, just wondering, did you use a program to figure this out or some O.G. wisdom?

I use WinISD version 0.50a7. There is a new version 0.6 but it's pretty buggy at the moment. Version 0.50a7 will get you close enough to what you want to know.

Mike, I have another question. Is the enclosure volume before or after displacement?

Thanks,
