The Usher Grand Tower

With new US distribution, by the Katli Audio Co. from LA, the Taiwanese Usher loudspeaker manufacturer premiered its Grand Tower flagship ($37,800/pair) at CES. Combining Usher’s diamond-dome tweeter with two in-house 7" midrange units and two Eton 11" woofers, the Grand Tower weighs 500 lbs and has a claimed low-frequency extension of 24Hz, with a 90dB sensitivity. My experience of a percussion recording suggests that both specifications are valid!
