Do I need a subwoofer to improve the sound of my speakers?

Most of our floor-standing speakers can also be used without a subwoofer, as they are very broad in frequency response. Smaller speakers, in particular, benefit from the support in the low-frequency range provided by a subwoofer. The load capacity of the speakers increases when a subwoofer takes over the low-frequency work and the bookshelf speakers are relieved of these frequencies by a high-pass filter in the amplifier. As a result, the small speakers can play more freely and often reward this with improved spatial imaging.
