Прочие устройства — Line Magnetic TA-4151

The Line Magnetic TA-4151 is a large field-coil loudspeaker driver with a 13.3-inch diaphragm, part of the maker's range of components for building vintage-style horn and baffle speakers. Line Magnetic specialises in reproductions of classic Western Electric drivers, and the TA-4151 belongs to that family.

Key specs that matter

Nominal impedance is 8 ohms and the frequency range runs from 40 Hz to 7.5 kHz, a wide band that lets the driver cover bass and much of the midrange. Power handling is 15 W. The unit weighs 20 kg.

Engineering and use context

Its motor uses a field coil rather than a permanent magnet, so the driver needs a separate DC excitation supply to operate. The low power rating points to high-efficiency systems powered by low-output tube amplifiers, and the limited upper range means a separate high-frequency driver and a crossover are needed to complete a full-range loudspeaker.
