The Subwoofer

The subwoofer extends the existing bass below 80-120 Hz. Since our ears have problems in locating low frequencies, one subwoofer is sufficient in a stereo or home cinema set-up and doesn't need to be positioned in front of the listener. Most subwoofers have a built-in amplifier to allow the individual adjustment of volume and low bass equalisation.

The subwoofer's driver(s) should have a solid basket, a rigid cone and a strong magnet.

Alcone by RCM

The following Alcone subwoofers have a strong magnet ensuring highest possible precision in reproducing bass. The cone is extremely rigid guaranteeing bass without dissipated power.
