I have done this I think it makes a diference
Anyone got any views? (opens can of Worms)

Do you mean electrical or physical grounding? I assume electrical, in which case there may be an improvement in RF shielding to reduce the level of interference fed back to your amplifier. Tannoy do this but I haven't seen any evidence that it solves problems in well designed amplifiers, and I would normally expect the crossover to filter out a lot of RF transmission. Obviously only worth doing if your chassis is die cast metal or pressed steel.
