The Horizon i-DS3 has a built-in 100W amplifier, driving dual 9cm woofers and 13mm tweeters.
The wireless subwoofer is a downward-firing, ported design, with a frequency response of 35Hz-150Hz. The built-in 2.4Ghz wireless transmitter means it can be placed anywhere in the room.
Boston's Horizon i-DS3 accommodates any iPhone or iPod with dock connector, and the mini remote control gives easy across-the-room access to the usual iPod commands.
If you want to show off your photos or videos on your TV, the unit is equipped with S-Video and composite video outputs. And the dock can be fitted with a range of optional grilles in different colours.
You'll be able to buy the i-DS3 in the UK from March for around £450.
