My TV is a BeoVision 4-103 driven by a BeoSystem 3; my front speakers are BeoLab 90s and my rears are BeoLab 5s (which may be upgraded to BeoLab 50s at some point).
My issue is that the BeoSystem 3 won't recognise BeoLab 90s (or indeed 50s), so I've had to assign all four external speakers as BeoLab 5s. This means that the BS3 doesn't recognise the BL90s' 100-millisecond latency, so when I watch films or listen to music in surround sound I get an echo effect between the centre, front and rear speakers. I can correct this by switching the BL90s to low latency, but it seems a pity not to enjoy them to their fullest effect.
A BeoSystem 4 would solve the echo problem, but create other issues, as I believe it cannot control my TV's stand or ACM. Is there a way around this?
