Entertainment Audio Production Business requires new logo

This is what Logo should incorporate the business name was looking for in their logo design

We require a new logo for our Audio production business based in Melbourne Australia. We would also consider a new twist on the existing logo or possibly for the existing logo to be "polished up" a little.
Our core business is supplying high end audio systems for concerts, gala balls, school concerts, festivals, functions, product releases, corporate meetings and company Annual General Meetings and basically any event that requires someone who is talking/singing/performing to be heard by a mass audience.
We basically supply the audio system(s) suitable for the event, we set it up, operate it, then pack it away and take it back to the factory where it is stored untill the next event.

Please see the current logo for colours we would prefer.
The logo will be used on the website, on invoices,letter heads and business cards. It will also be used on stickers to label our equipment and also to stencil the road cases that protect the equipment. Read more
