Hardware, 3" 8 Ohm Speaker unavailable in Egypt, Substituted 4 Ohm

[ForrestErickson]

Describe the Failure / Bug
A clear and concise description of what the failure / bug is. Describe the problem NOT the fix.
Short Summary of the expected behavior:
We wanted to build Krakes in Egypt with 8 Ohm speakers (78x78 mm)

Short Summary of the buggy behavior:
Only 4 Ohm speakers were available.

We chose to use it but this requires that for these units the volume must not be set higher than 20 out of 30.
AKA about 66%
