This 16 x 9 mm "sugar cube" WOWSpeaker is a cell-phone-style driver that disappears into the tightest installs. It needs a sealed baffle or enclosure to perform, but once mounted it delivers surprisingly big sound for its size — perfect for space-restricted N and HO projects.
Pair it with a sound decoder from our DCC Decoders collection, browse more DCC Accessories, or shop the full Train Control Systems lineup.
What decoders does this work with?
It's an 8 Ω speaker that works with TCS WOWSound decoders and virtually any other DCC sound decoder rated for an 8-ohm load.
Do I need an enclosure or baffle?
Yes. Speakers need a sealed enclosure or baffle (or a sealed cavity in the shell) to move air and produce full sound — mounting it in open air will sound thin.
What scales can use it?
Any scale with enough room to mount it. Smaller drivers suit N and HO; larger round and high-bass speakers shine in HO, O, and G.
