VOTU has two 10" (254 mm) drivers that deliver bass from the very bottom up to 800 Hz, then a 3" soft dome emitter comes into play, covering the entire critical midrange range up to 4 kHz, and then a powerful 34 mm soft dome tweeter takes over. The MF dome is located above the tweeter to improve their integration.
