RS-II is a 2.5-way speaker system equipped with three active drivers: one high-frequency and two low-medium. A pair of identical mid-bass drivers sound in the low frequency range, in the midrange only the upper speaker works. This solution provides a large area of radiation at low frequencies and a wide pattern at medium and high frequencies.
The slot-type reflex port has a large cross-sectional area, placed vertically along the rear wall of the cabinet with an outlet in its lower part. This port design contributes to the high efficiency of low frequency radiation, provides a fast attack and depth of the bass range.
