Hello, I've been working through this tutorial, which has been extremely great and detailed so far, however, I've come to a point in the tutorial where I'm completely stumped as to what I'm suppose to do next. The section I'm working through is on Page 4 (of 6) and involves creating the High Toner/Tweeter for the speaker set. Mianly in the first paragraph, I'm not entirely sure what I'm suppose to do next after having created the inital cube. What does it mean by after creating the initial cube, 'pierce' the cube straight away? As well, I'm lost with the next bits as well where it talks about creating a rectangle and a circle.

Thank you very much for your time, and help would be greatly appreciated.

Cheers.
