Premium flat active subwoofer

The T 4000 SW bridges the divide between easy room integration and mega bass playback. An incredibly flat enclosure makes it easy to place the T 4000 where it won’t get in your way. That small space behind the sofa or coffee table is enough. In fact, the T 4000 is so slender, it can even be positioned under most sofas, wall mounted or used to support your television. Its highly robust, reinforced MDF enclosure was designed to withstand the weight of conventional televisions making it the ideal sonic pedestal.

In spite of its highly convenient dimensions, T 4000 is driven by 250 watts for power to spare. A three driver system that is already successfully employed in Teufel’s highly popular System 4 THX model is used here as well. This ensures balanced playback based on THX standards and produces powerful, deep bass all the way down to 35 Hz for home cinema that makes you part of the action. Even very high levels are accompanied by very little distortion thanks to the long throw-drivers used.

The T 4000 is a universal subwoofer that can be combined with just about any home cinema set, even very high-performance models. This means the T 4000 is perfect for accompanying surround speakers or for giving an already complete 5.1 set an extra boost.
