Description
An 18 × 35 × 12.0 mm speaker with a passive radiator, wired at 4 Ω for higher volume. The passive diaphragm gives this compact driver deep bass beyond its size, while the 4 Ω impedance maximises loudness from the LokSound 5 amplifier.
A punchy, small-footprint option for H0 models, fully supported by LokSound 5.
- Size: 18 × 35 × 12.0 mm
