3. feed the tweeter The terminals are insulated to prevent any likelihood of electrical shock even when the speakers are used with the highest powered amplifiers and accept a variety of cable terminations to suit most applications Bi wiring is the preferred method of connection and involves the use of separate cables from the amplifier to each pair of terminals The separation of the signal paths improves the resolution of low level detail and allows the user to optimise the type of cable to the frequency range of use figure 2 Should you not want to bi wire perhaps during the initial set up procedure or because you do not want to see a multitude of cables in the room short cables are provided to link both positive and both negative speaker terminals together figure 3 When using the links insert the spade into the slot in the side of one terminal and the crimped pin into the round side hole in the other There is enough clearance to insert a spade connector from the amplifier into the same terminal as the crimped pin Ensure each positive terminal on the speaker coloured red is connected to the positive output terminal of the amplifier and negative coloured black to negative Incorrect connection can result in poor imaging and loss of bass When bi wiring do not use the linking cables Take extra care with the polarity of the connections as incorrect connection can also impair the frequency response through
