Just announced in the States at Sony's Open House trade event is a trio of new DVD home cinema in a box systems, with two models having wireless audio capability.

The new systems claim 1,000W total power output, and each has an integrated five-disc CD/DVD changer. And in addition to the company's DM Port system, allowing integration with portable and wireless devices, the systems also come complete with an iPod cradle, and an easy set-up disc.

Two of the systems, the DAV-HDX589W (above) and DAV-HDX587WC (below), offer Sony's S-AIR wireless audio transmission, the former having WAHT-SA10 wireless rear speakers and the latter AIR-SA10 wireless multiroom operation.

They both also have upscaling, Digital Cinema Auto Calibration and a range of technologies to enhance audio from both portable audio and DVDs, including Sony's Dialogue Enhancer.

The two systems go on sale in the States this month at around $430 (£300) apiece.

More after the break

The budget DAV-HDX285 system (below) comes with smaller speakers than the more upmarket models, and is 'S-AIR-ready', needing the addition of a transmitter to do the wireless thing. It will sell for around $300.

Finally Sony has a new soundbar system designed to complement its latest flatscreen TVs. There's no player built-in, but the slimline HT-CT500 3.1-channel soundbar speaker system (below), which goes on sale in June, has surround processing and amplification built-in, handles the latest HD audio codecs, and comes complete with a subwoofer. It will sell for around $500.
