Tetra 505-C

The center of attention

During the past few years, technological advances in TV viewing like HDTV, plasma/LCD screens and large-scale projectors have revolutionized what we see at home. Unfortunately, while most enjoy hi-resolution video, they settle for low-resolution audio. At Tetra, we want to complete the picture for you.

Introducing the 505-C. In a surround sound recording, the center channel is the key to optimizing on-screen voice intelligibility and the sense of being there. The 505-C employs a 2.25" dome mid-range driver capable of accurately reproducing the human voice and dispersing it in a wide angle.

With the 505-C you don't have to sit in the middle to hear what is being said on screen. The end result is a listening instrument capable of impeccable realism and clarity. Mix and match any Tetra Listening Instruments with our 505-C and you have a true hi-resolution home theatre audio experience. It's so good in fact that Tetra owners are known for listening to their stereo records in 3, 5 or 7 channel. It's that good! In fact, we like to say our 505-C is the best center channel you'll never hear. Until you turn it off, that is. Find out for yourself why the 505-C is the 'Center of Attention' for so many.
