The Exile XM9 Hybrid Tower setup blends form, function and performance in a way that no other configuration can. The sound stage is both deep for the wakeboarder -(XM9's) and wide for the wake surfer/ party cove - (SXT65q's). The collective midbass accousitc signature is jaw dropping at 80 feet and beyond, yet smooth enough inside the boat and or out at wake surf distances. Power wise, the XM9 configuration requires a dedicated Harpoon amplifier for the SXT speakers and another dedicated amplifier running the XM9's. This system requires proper tuning and and is advanced in its setup. If you want absolute highend, the Hybrid is for you!!!
