Spica TC-50 Speakers USED
The Spica TC-50 is a deceptively simple two-way loudspeaker based on a 6-1/2 inch acoustically suspended woofer and a 1 inch dome type tweeter. Its crossover network is truly state-of-the-art, in parts quality, circuit layout and, of course, design. The compact speaker is the result of exhaustive research and the latest technology in computer assisted optimization. Designer John Bau had indeed pushed the limits with tools available for the period, creating a time-aligned design with remarkable imaging qualities. Close tolerances were maintained during production and units were serialized to ensure a optimal left/right matching.
Two-way, stand-mounted loudspeaker. Drive-units: 1″ soft-dome tweeter, 6.5″ pulp-cone woofer. Low-frequency alignment: sealed-box with Q=0.78. Crossover frequency: 2kHz. Crossover: high-pass slope, approximately first-order, 6dB/octave; low-pass slope, fourth-order, 24dB/octave, Bessel; both drivers connected with the same polarity. Frequency response: 60Hz-17kHz -3dB. Sensitivity: 84dB/W/m. Nominal impedance: 4 ohms (3.6 ohms minimum at 4kHz). Amplifier requirements: 25-100W. Maximum power handling: 50W continuous, 100W peak.
