Multi-room streaming via Bluetooth opens up a whole new world of music to enjoy, with direct control via Spotify Connect and in-app services. It is also possible to play from a personal music collection via USB mass storage devices or local networks.
The One S (£219.99) is perfect for use in smaller rooms, such as the bathroom, office or bedroom, where there might not be enough space for larger speaker sets.
When the One S is not enough, but there is no room for separate stereo speakers, the One M (£449.99) comes into play. With four tweeters, two mid-range drivers, a woofer and two additional passive bass membranes on the sides, this compact, all-in-one sound system is extremely powerful.
The shelf-streaming Teufel Stereo M (£879.99) speaker pair will satisfy even the most demanding of audiophiles. Each speaker is equipped with a woofer and a coaxial driver developed by Teufel in Berlin, which combines a mid-range driver and a tweeter. For all three outputs (high, medium and low frequencies) there is a separate, built-in Class-D amplifier.
The elegant, floor-standing Stereo L (£1599.99) speakers deliver the best Hi-Fi stereo sound with enormous depth. Coaxial drivers provide an almost perfect time correlation between high and mid-range frequencies, and give the Stereo L superb precision. Six high-quality Class-D power amplifiers drive the tweeters, mid-range and bass drivers in each of the two speakers, together producing a remarkable 500W total power.
