The TrAx50 adds a .75-inch alloy tweeter to the wide range 5.25-inch ACAD driver build specifically for this series. The addition of the tweeter adds sparkling high frequency details and a broader sonic range to these models. The result is excellent high fidelity performance from compact and unobtrusive speakers that can be installed just about anywhere. Stereo sound from a single driver assembly makes this model ideal for locations where people are moving about or may not be standing/seated in “the sweet spot”. The possibilities are almost endless including the ceiling in a bathroom or stall shower, hallways, foyers, workshops, garages and so many more. And the best part is you simply don’t have to worry about the temperature or the weather.
