I have a silly question, I have speakers that require .75cft and the box I found only has .60. Will this work? Sorry don't know much about stereo equipment.

Provided the drivers physically fit into the box, it will be lacking low end. You can help, but not solve the problem by stuffing the box with a bag of polyfill (doll stuffing from a craft/sewing store or Walmart) or two.
