Most you'll likely want two different kinds of Twitter accounts: one for yourself as an individual and another for you company or its major offering.
For instance: @DougLucy is for Doug's individual opinion, perspective or advice and @AdLinea is for Doug's company's topic-specific advice and tips.
People will be following each Twitter account you create and expecting a certain kind of posting in each. If you simply create a personal account and post a mix of personal status updates, personal opinion and tips about your home theater business, the people following your Twitter accounts may like hearing aboutone of those, but not the others.
If you consider "what kind of information and value will I be delivering?" and create one Twitter account for each type of infomratin or each market segment that info will appeal to, you'll increase the value-to-noise ratio in your Tweets.
