All of our Level THREE Bookshelf, Center, and Tower Speakers include two pairs of 5-way gold-plated binding post connections. Two pairs of binding posts allow for a standard connection (shown here) or a bi-wire or bi-amp connection (read more). 5-way binding posts allow for your cable to be connected by either: 1. bare wire (shown), 2. spade connectors, 3. pin connectors, 4. individual banana plugs, or 5. dual banana plugs.
About 80% of our customers connect using a standard connection and 20% prefer to bi-wire or bi-amp. With a standard connection, you simply run good quality 2-conductor cable to each speaker.
With a standard connection, the gold-plated jumpers (included and pre-installed with every Level THREE speaker) are kept in place to connect the top binding posts with the bottom binding posts. One of the two cable conductors is connected to either of the positive (red) posts and the other conductor is connected to either of the negative (black) posts.
It is important that the cable maintain polarity between the speaker and its amplifier channel, i.e. maintain positive to positive and negative to negative. If two speakers are connected and one speaker is wired with reverse polarity (called "out of phase"), most of the sound from the two speakers will essentially cancel each other out, resulting in a weak or "thin" sound.
