A soundplate is a sound centre that is suitable for setting up your TV. The Steenssen soundplate has a built-in subwoofer, so you don't have to place a separate subwoofer in your room and you also don't have the hassle of tidying up wiring.
The subwoofers in the Steenssen soundplates ensure that the sound waves pass through built-in walls with a detour through the cabinet and leave from the bottom of the soundplate.
Often a subwoofer has to be placed separately from the other speakers because the perfect sound requires a number of nanoseconds between the different sound sources. With the soundplates of the TT Grand series and the ACTION series, however, the subwoofer is built in expertly, so that everything is processed in one sleek unit.
