Description
A 20 mm round speaker (1–2 W) with sound chamber, wired at 4 Ω for higher volume from the LokSound 5 amplifier. The round format suits H0 boilers and small diesels, and the chamber gives it surprising punch for its size.
Fully supported by LokSound 5 decoders, with louder output than a comparable 8 Ω driver.
- Size: 20 mm, round (1–2 W)
- Impedance: 4 Ω (higher volume)
- Includes: sound chamber
- Best for: H0 boilers, small diesels
Brand-new, genuine ESU (Electronic Solutions Ulm). Ships from our shop in Oakville, Ontario.
