If you're in a dedicated studio building (or a detached house!), an active subwoofer is the perfect way to give you an accurate reference for your bass and low frequencies when mixing and making music.
Usually filtering frequencies below around 300hz, these active studio subwoofers allow you to tailor a 'cut-off' frequency and independently tweak the volume and output of your bass, depending on your room size.
Typically, most active studio monitors are made to be as 'flat' on the frequency response as possible, so a subwoofer is a great way to reinforce your bass so you can always reference the full range of sound, especially for Electronic musicians, Hip-Hop producers and DJs.
