In short, home theatres have never been so inexpensive or hassle-free. Research firm GfK on the first six months of 2015 show the consumer electronics market is booming but growing in new directions. In televisions, ultra high-definition screens are the fastest growing market but their popularity is merely consolidating after the FIFA World Cup last year sparked soccer fans around the world upgrading their old TVs. Television screens continue to grow in size, however, with GfK reporting the average size of TVs in Europe during 2010 was 79cm and is now 97cm, even though the prices of new televisions have dropped. When it comes to sound systems, the trend is for simplicity and wireless connectivity, with all-in-one soundbars the growth market. The research firm’s figures show more than 11 million soundbars were sold globally last year — 64 per cent more than 2013. This year, GfK forecasts that figure will rise again to more than 14 million soundbars. Soundbars with external subwoofers are particularly hot items, according to the company, and Bluetooth connectivity is the key factor in purchasing decisions as consumers increasingly opt for the simplicity of playing music from smartphones and tablets. For consumers, the good news with all of these trends is that creating a home-theatre or listening to high quality music throughout your home doesn’t need to cost a small fortune. Here are five tips for creating a home theatre on a budget. 1. Cheaper big-screen TVs: Televisions are not just getting more advanced, they’re becoming cheaper by thousands of dollars. While the first OLED (organic light-emitting diode) televisions cost $10,000 when they launched in Australia in 2013, but this year LG launched an ultra high-definition 55-inch OLED TV with four times the pixels for $4000 less. Similarly, Samsung has dropped the price of its 78-inch Series 9 SUHD television by $3000 since its launch earlier this year, now selling it for $9000, while a more modestly sized 48-inch SUHD TV costs $3300 -- $1700 less. 2. Adding smarts: If you’re not ready to upgrade your television, there are still ways to get apps and streaming content to show on the biggest screen in your home.
