Buying Tips

The Multi Disc Resume function memorizes the stop position for several DVDs, so that the DVD player will resume playback from where you last stopped. The DVD player can resume playback even when the disc has been removed from the DVD player.

The major factors to consider when buying a Home Theatre system include required volume levels, connectivity options and speaker placement. For the best listening experience, the speakers should be placed at least two feet from room boundaries.

The Centre Speaker should be placed above or below the TV at ear level. The Front Left and Right Speakers should be 5 to 11 feet apart, at an angle of 20 to 30 degrees with respect to the Television. The Surround Speaker should be placed above ear level, slightly behind the listener.

My First and Best Home Theater

I have Been Using These For 2 Weeks Now and I Must Say That They Rock!!!

Their Volume Output is Great and Come With Multiple Input Options Like USB and AUX..Even A FM Tuner Is Built In ..

Total Output Is 1000 W But They Sound Much More Than That if You Have A Sony Bravia TV Then Don't Think Just Buy Them !!! They Both Work together Just Like They Are Made For Each Other...

If You Are Thinking To Get DAV-DZ340K Then Consider An Upgrade Of 3k as It Would Be The Best 3k Spent On A HT !!!

Wow man...!

I'm using the same stuff for over 10 months, still the guy is booming and breaking my house! Even the windows use to vibrate when it plays. The only defect sony has is after a certain high sound and increased the bass wont increase as the volume. Any way in short i love to say "Paka Item"
