i have a pair of royd apex`s and they are biamped via 2 linn lk280`s. i have long known the royds can be made active, and it says in the instructions: " active: unplug 4 wires from the back of the speaker. connect bass amp to yellow and black sockets in cabinet back. connect tweeter amp to red and blue sockets in cabinet back. crossover frequency of amplifiers should be 2700Hz to 3500Hz. no equalisation is required." does this mean i do not need any form of active crossover, just plug the speaker cables in from the power amps as it says???
