Rated 0 out of 5

I have the RBH SI-831/R9 Front LCR’s on permanent demonstration in our new Dark room system and they beat anything i’ve ever heard in that and many others rooms i’ve had the pleasure to listen in. Pinpoint audio accuracy, clean uncoloured audio reproduction, these speakers are simply wonderful.


Combining the award-winning performance of its SV-831R sibling with the visual benefits of custom integration, the SI-831R is specifically designed to be discreetly placed behind acoustically transparent screens. The SV-831R employs three 8-inch aluminium cone woofers and an AMT aero-striction tweeter, and is capable of handling copious amounts of power. The SI-831R can deliver paramount fidelity and performance for even the largest home theatre or listening room.
