Hey man,
Here is the initial idea I came up with for Cooler Beat's logo #11. I took the look and feel of the actual speakers themselves and incorporated that into a round emblem that is identical both right-side up and upside down. So, if you are branding certain things (turn tables, coolers, records, apparel, etc.), people can read your logo no matter how it happens to be oriented when they see it.
Let me know what you think about the idea and the colors, and we can work this over until it's exactly how you want it.
Thanks.
