Teufel Concept C 300 Wireless review

Taking Teufel's Concept C 300 wireless out of its box is a challenge in itself; the subwoofer is massive and weighs a back-straining 18kg. Thankfully, it doesn't need to be placed next to your computer because it includes a wireless transmitter for cable-free audio.

An antenna on the back of the subwoofer communicates with your PC through a USB adaptor; this simplifies setup but it also means you won't be able to use a dedicated sound card if you have one installed. With no cable restrictions, you can hide the subwoofer in the corner of a room for better acoustics. Devices other than computers can be connected to the subwoofer using the stereo phono input, but where they can be placed will be determined by the length of the cable used to connect them.

The mug-sized left and right speakers connect to the subwoofer using traditional speaker wire, although none is included in the box. The benefit of this is that you can buy the lengths you require to position the speakers anywhere in a room. Both speakers come with small stands, but you can swap them for others or wall-mount them with compatible brackets.

Power, volume, bass and input selection are all controlled by the wireless remote. It uses radio transmissions rather than infrared to communicate with the subwoofer, so you don't need to be able to see it to change settings. Unfortunately, without a visual indicator for the volume and bass levels it's difficult to tell how loud it will be when turning it on. You also can't change the volume through Windows; the only option is to use the wireless remote.

Throughout our testing, music sounded warm and well-rounded. Acoustic tracks were incredibly clear, with all the smaller details preserved. We had to raise the bass setting for our heavier tracks, as they didn't have the strength we would expect at the default level. Once we'd changed it however, it was enough to fill our test room with rumble.

Teufel's products are often expensive, and the Concept C 300 wireless is no exception. It sounds fantastic, but the wireless functionality will only appeal to those that don't have the room for a subwoofer next to their computer. Anyone that does have the space has little reason to choose this over a cheaper 2.1 set.
