Tiny, but very powerful speaker including two resonator boxes. I can not express how exceptionally good this little speaker is. Released in 2025, it is as good as the classic 'Sugarcube' speaker, but then much smaller. Great choice for small model trains in scales N, 009/H0e and OO/H0. The sound is so loud, that when in use at home, you'll prefer to turn down the volume for a more realistic experience. Size speaker: 8 mm x 13 mm x 2.6 mm Size resonator box 1: 8 mm x 13 mm x 6 mm Size resonator box 2: 8 mm x 13 mm x 3 mm Efficiency dBA: 90 Frequency range: 400Hz ~ 20kHz Power - Rated: 800mW Power - Max: 1W You get two resonator boxes, but choose one which fits your model the best. The chosen resonator box has to be glued on the speaker side, not on the rear, metal side for maximum result. If you have any question, please ask! I'm happy to assist.
