Concentric drivers that cross-over at 120hz, 700hz and 17khz made me scratched my head. How does it suppose to sound? This is more expensive than the MBL just reviewed here. I don't think it is even comparable or it performs anywhere near the MBL. HK$39.8萬, gimme a break.. I am more used to seeing one big concentric driver speaker system from Tannoy.
