Description
A twin-driver sound kit pairing two 11 × 15 mm speakers with ESU's modular Soundbox enclosure system. The interlocking enclosure pieces let you build a tuned chamber matched to common large footprints (28 mm, 20 × 40 mm or 16 × 35 mm), so you can fit the biggest sound your model's space allows.
Two drivers move far more air than one, giving louder, deeper H0 and small-0 sound. Works with any ESU LokSound decoder.
- Drivers: 2 × 11 × 15 mm
- System: modular Soundbox enclosure kit
- Best for: louder H0 / small 0 installs
Brand-new, genuine ESU (Electronic Solutions Ulm). Ships from our shop in Oakville, Ontario.
