The Perfect Home Theater?

Posted April 08, 2009 8:15 AM

Sit back and close your eyes. Now, forget the recession for a minute; dream about the perfect home theater. Just this week, I heard about flat flexible speakers while another publication suggested ways to hide your flat screen HDTV when not in use by sliding something in front of it. If only the sky were the limit, what would you envision being in your home theater?

The preceding article is a "sneak peek" from Display Technologies, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Display Technologies today.

Well, I might comment on the flat, flexible speakers. This sounds like a slightly more compact version of electrostatic speakers. Electrostatic speakers have a nice advantage of cone speakers in that they produce a very broad range of frequency from a single driver. This reduces a lot of phase distortion and time alignment issues between conventional woofers, midranges, and tweeters. Sound coming from these speakers is very clear and "imaging" is excellent. They are relatively easy for the home builder to make if anyone would like to try.

The downside is that a single sheet driver does very poorly with bass and treble. Bass requires a lot of air movement and you need huge areas or sheets to move the volume of air required to get deep enough bass. Large area sheets also tend to beam the high frequencies, so if you move slightly off-axis of the speaker sheet your treble goes away.

Martin-Logan works around some of these problems by bending the electrostatic sheet into a slight curve and then adds a conventional woofer for the bass. This addresses some of the bass and treble issues, but is not a perfect solution.

As for the flat display technologies, I would like to see how bright it actually is. I would assume getting anything that is extremely thin to radiate enough lumens to be a considerable challenge. I still use a projector to get a large screen display, which rolls nicely into a hidden cove of the wall for me.

However, the single most challenging aspect for home theater is not reproduction of sound nor clarity and brightness of image, but program content. I'm getting a little tired of every movie turning into a fantasy shoot-em-up with impossible human feats of stupidity.

Well what else is there? You can have sex and violence or violent sex or more of the same. Soloman is reputed to have said "there is nothing new under the sun".

Some of the better flicks, to my mind are those based on true stories. It's just to bad they even try to spice those up.

A friend of mine made those, with added sub-woofers for the low range and even the amplifier is one with radio-tubes, it is an amazing sound experience. Making them is not easy.

There are a lot of good independent movies, but for good drama or moving stories, you hardly need an over the top sound-system.
