I considered the services which Sowa Entertainment offers and tried to incorporate them into the logo's image. Using a speaker-like icon represented by a rectangle containing a small circle above a larger circle, like the high and low cones on a speaker. I added in the film strip coming from the bottom, quoting the action of film coming from the photobooth.
The colors degrade very gracefully from color to greyscale. It also works at various sizes.
Thank you for your entries. Unfortunately, I don't want to emphasize the tools used to create the end product. In my sales and marketing I work hard to emphasize the final service that we deliver (the fun party, high-end service) rather than the equipment we use (speakers, computers, lights, equalizers, microphones, music, headphones, film, etc.) so please keep that in mind that our tools (music, speakers, computers, lights, microphones, etc.) are not what we want to emphasize in our logo - we want to emphasize the FUN and ENERGY that we create through our HIGH-END SERVICE.
