High quality 20x20x7mm speaker in a fully sealed enclosure for DCC sound models. Its a small speaker which will fit many models, it's 8 ohm so works with Loksound 4, 5 and Zimo and TTS decoders. If you have the space you can also attach two of these in series to one sound decoder. These speakers may be small but offer a big, powerful sound. The second photo shows two fitted to a Bachmann class 47.
More speakers available in my other items. I offer a fitting service for people who don't want to fit speakers on their own.
