DCCS - "Thunder Twin Short" High Performance Dynamic Speaker 11x15mm

One of our most popular and best-selling speakers, the “Thunder” has been around since 2013. It became the speaker of choice, popular with modellers installing sound, as they were impressed with the quality and sound output from these small dynamic speakers.

Now it finally gets some new additions to expand its line-up.


The DCCS – “THUNDER TWIN SHORT” consists of two Thunder speakers installed in a precision engineered side-by-side short format single enclosure. The orientation of the speakers is that they are joined on the longer side, creating a shorter but wider sized speaker, enabling it to be installed in locomotives where this type of space is available for a speaker.


Don't be fooled by their size, as these speakers show a significant improvement in sound quality over other speakers on the market and will provide an outstanding sound performance.


This twin speaker format is designed to be wired in parallel to provide 4-ohm impedance perfect for ESU LokSound and Zimo* decoders or can be wired in series to provide 16 ohms, allowing it to be used with most brands of sound decoders.
