Deals or Advertising budget for hi fi speaker companies in india

Well, i am little surprised at all the hi fi speaker companies which sell their products in india regarding advertising. Only some of the people really know about these companies. People are willing to spend on hi fi gear, but they don't know where to find the best deals or best speakers in their budget.
i did not see any adds or any deals around the diwali or new year from these companies. Are these companies are really serious about doing business in india.
Is there any company which has set aside certain amount of budget for advertising.
i want to know the responses from commercial members.
