As I know Brax better on amp, but speaker not sure..... I think U need more exposure in ICE field..
Scanspeak is OEM, they make alot top model speaker for several Brand but follow their spec..
a) Alpine F#1 (Z15M,Z18T) base on Scan Revelator & Ring Radiator
b) Alpine F17T base on Vifa
c) Xetec top series/model
d) etc
Just for info only.. to member who own/using Xetec amp, kindly be noticed The Xetec Germany is no longer available & now Xetec GMBH under 'LIQUIDATION'
