More Information Brand Train Control Systems (TCS) Item Number 1695 Type WOWSpeaker (DCC sound speaker) Size 32 mm (1.26") round, 5.1 mm deep Impedance 8 Ω Condition New FAQ 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.
