Optimized low-frequency response.

The Bass Control is a polyethylene plug designed for use with bass-reflex speakers with a 70 mm diameter bass-reflex port. The Bass Control closes the bass port, thus turning the speaker into a closed box with about 3 dB reduction in bass level. If, for architectural or aesthetic reasons, the loudspeaker cannot be set up in an optimum position to achieve flattest low-frequency response, the Bass Control balances the bass surplus caused by room acoustics.
