Прочие устройства — Line Magnetic LM-594

The Line Magnetic LM-594 is a compression driver intended for horn-loaded loudspeaker systems. Its passband spans both the midrange and the treble, so a single LM-594 can take over both the midrange and the treble in a suitably designed horn, reducing the number of crossover transitions a multi-way build needs.

Key specs that matter

Nominal impedance is 16 ohms and rated power handling is 25 W. The frequency range of 600 Hz to 20 kHz defines where the horn and crossover should place it. The 16 ohm load is higher than the 8 ohm figure common in domestic speakers, which matters when calculating crossover component values and when choosing the output tap of a tube amplifier.

Pairing

The LM-594 needs a horn whose cutoff sits comfortably below the lower limit of the driver, plus a crossover that hands the lower octaves to a separate bass section. Its modest power rating fits low-power tube amplification of the kind Line Magnetic builds itself.
