THX announced the launch of the THX Certified Home Theater program for custom home theater installations and new residential developments. We met with John Dahl who explained the certification process to us in detail. The THX Certified Home Theatre program provides designers and system integrators with audio and visual specifications for the design of dedicated home theatre rooms. For the first time, THX will afford homeowners the luxury of having a certified state-of-the-art THX home theatre environment, a level of excellence previously reserved for film industry professionals. The certification comes with a serialized plaque that can be hung on the wall, designating the theater as THX Certified.

By leveraging the company's more than 20 years of expertise in film post-production, commercial cinema and studio design, and consumer electronics, the THX Certified Home Theater program provides an optimized setting for experiencing films and other multi-media content in the home. The program will serve as an extension of the THX Certified consumer electronics and professional mixing studio programs.

"Home theater rooms with the THX Certified Home Theatre plaque on the wall will deliver an exceptional level of audio and video performance," said Joseph Lias, president of THX Ltd. "Because the THX brand represents superior quality, we are confident that the THX Certified Home Theater program will be embraced by the professional designer and integrator communities, as well as home theater enthusiasts."

The THX Certified Home Theater specifications will include strict guidelines for room layout and design, acoustics, lighting, background noise, and equipment positioning and installation. To roll out this new initiative, THX will be partnering with the nation's leading system integrators and custom designers, as well as its manufacturing partners in the consumer electronics industry.

The new program is almost certainly guaranteed to be a success with all of the high-end home theaters being built around the country (and the world for that matter). This is an idea and concept that has been long in the making (and was highly requested in the past). It's great to see THX expand into the home theater market in this way and add a whole new dimension to their line of certifications.
