Here a few packaging concepts I use, and it usually takes me about 6 hours to pack up a unit from scratch:

- No delicate item that protrudes (knobs, switches, levers, etc.) should receive any contact, in the case of a drop.
- Packaging that is too stiff will simply couple impact forces directly to the unit, so stiff packaging is only good for outer layers for box bracing, or inner layers to ensure the parts to receive no contact are protected.
- Packaging that is too soft will simply collapse until vulnerable parts make contact with packaging walls, or until stiffer parts of the package couple remaining impact forces to the unit (uphostery foam is definitely not acceptable).
- Packaging that will not recover after impact is unsuitable, since impacts will tend to repackage the unit in unpredictable/undesireable ways (bubble wrap tend to pop, so it is good for one good impact, then it does not recover, leaving the unit flopping around loose).
- The primary job of padding is to take the sharp leading edge off of impact forces, while compressing somewhat, bringing a unit to a stopped state to match the package.
- The outer box must remain sharp cornered, since soft outer boxes are harder to handle, causing them to get tossed like duffle bags (handle cuts in the sides of large packages are a definite benefit).
- The compressibility of padding is not what it appears to be at a static state. It will be revealed for sure when the package is experiencing several Gs.
- Rarely will any drop be square with a side, hence packaging must account for units shifting at any angle during an impact (especially important when protecting switches knobs, antennae, etc.)
- Truly and reliably protecting a heavy piece of audio gear from an 8 ft drop is a pipe dream (you might get lucky. You might not).
