I'm looking into building an enclosure that measures 34W (left to right) x 18.5D (back to front) x 14.5 in height. The speaker is going to sit on top, port firing back. This is an L port design. The port will be 3 inches wide. My question is, if I want to tune at 33Hz how long would the other part of the port have to be (the one that runs across the back of the box)?

I used RE's calculator for my last box a few years ago and it couldn't catch the lows for nothing, so I know something is not accurate about that calculator.

If someone could help me with this, I'd appreciate it.

Try Torres calculator.

When aero port is selected and you select that it's a flared port. The figure that it gives you for the length, is that from flare end to flare end, or is that just the tube length?
