Our Pioneer Elite X-SMC4-K shipped to us double boxed. We discarded the outside package since it was quite dirty from shipping. The inner box is a typical Pioneer brown box.
There is not much to see, but you do get an idea of the size.
The inner packaging was very good and used form foam inside of four bags that keep the foam pieces from dusting the inner components. The main unit was wrapped in a white closed cell foam sheet.
You receive a full printed manual in the package, a warranty paper as well. A FM antenna is also included as is a power brick and power cord for the brick.
