The Steam-Tweeters are a range of cylindircal micro systems designed to fit in the smallest of spaces. Suitable for use in smoke-boxes, boilers, cabs or even as an additional speaker in the tender to bring out more clarity of sound. Some of these systems may even fit well in HO narrow-gage or N scale steam locomotives.
Three systems are available in the following sizes:
Micro: 9mm Diameter x 16mmL x 8mmH
Medium: 11mm Diameter x 15mmL x 9.5mmH
Large: 11mm Diameter x 20mmL x 9.5mmH
If used in conjunction with a tender-mounted speaker, be sure to know that speaker's impedence and wiring accordingly. Soundtraxx and TCS are best suited with 8-16Ω speaker loads, while Loksound is happy with 4-8Ω speaker loads. Showm is a series-wiring diagram using a 4Ω tender-mounted speaker along with a Steam-Tweeter or Boiler-Barker.
These are 8Ω, 1W systems and come fully assembled and tested.
