I just bought an IDQ 12 and was trying to build a ported box with a slot port for it. Image Dynamics recommends putting it in a 1.25 cu. ft. box tuned at 30 Hz. What length should the port be to get it at 30 Hz? The box will measure 16 3/4" x 15" x 19 1/2" with the port being 1 3/4" wide x 13 1/2" tall. Also, will this box work or is it too small or too big?

that box is gonna be way to big if you are going for 1.25! I would do more like 15x15x15 after speaker displacement you will be right around 1.25 and for the port size I am sure sean or someone else with a box building program can help you out I dont have one.

No, please dont do a 15X15X15 box. You'll get a really bad response from the driver. A cubic box is not very good. Coz of the waves moving inside...
