Few years ago, I am started to change my speaker Ramsa to Yamaha. The Yamaha DXR series is great and I am waiting for the passive series.
The CBR10 have a great sound quality as same as the DXR10, but it is UNPOWERED PASSIVE!! The spectrum is smooth and flat, even the high or low end and easy for tuning.
Just the power is less then DXR, and the low end is little bit less then DXR10(Maybe it is because of the amplifier). But it it enough for the small stage monitor, even for the Main.
