The RFT B6401 'Cascada' is a compact 3-way floor-standing loudspeaker designed by RFT and first showcased at the Leipzig Spring Fair in 1988. With dimensions of 230 x 630 x 285 mm and a weight of 12 kg, the loudspeaker's cabinet is constructed from 18 mm thick particle board and features a bass reflex system with a net volume of 25 liters. It is capable of handling a nominal power of 50 W and supports a maximum power of 80 W, with an impedance of 4 Ohm. The frequency response spans from 35 Hz to 22 kHz, making it capable of reproducing deep bass sounds effectively. The speaker consists of three drivers: a bass driver (L 2621 S) with a 16 cm diameter aimed at deep frequencies, a midrange driver (L 2464) providing coverage in the midrange, and a high-frequency driver (L 9806) for clear treble outputs. The crossover frequencies between the drivers are set at 1.5 kHz and 4.5 kHz, with a sensitivity rating of 86 dB and an operating power of 9 W. The speaker is available in various finishes, such as brown, black, and anthracite, and features a removable front grille that uses a wire mesh to protect the drivers. Overall, the Cascada has a unique sound profile that excels at delivering deep bass compared to other speakers from the era, though some listeners note a slightly subdued midrange and treble performance.
