Полочная акустика — Fischer & Fischer KLEIN

The Fischer & Fischer KLEIN is a compact two-way passive loudspeaker from the German maker known for cabinets built from natural slate. It is a bass reflex design with an external crossover.

Key specs that matter

The KLEIN covers 60 Hz to 30 kHz within 3 dB, nominal impedance is 4 ohms and sensitivity is 85 dB at 1 W and 1 m. A 100 mm long-throw paper cone woofer works with a 22 mm fabric dome tweeter. The slate cabinet is 220 mm high, 130 mm wide and 200 mm deep, and each unit weighs 7.1 kg.

Engineering and use context

Slate is used because it is highly resonance-free, so the enclosure needs no additional internal damping. The second-order, impedance-corrected crossover sits in a separate 165 x 85 x 200 mm box outside the small slate cabinet.

Alternatives

The larger slate two-way SN/SL 70 is the other compact model in the Fischer & Fischer range.
