Some multi-channel receivers allow you to use four of the available amplification channels to independently power the upper and lower sets of binding posts. Some audio enthusiasts feel that bi-amping improves the sound during more demanding moments of music or movies. Essentially it is like having four-wheel-drive when going off road; on rough, rocky terrain it is often better to send power directly to each of the wheels. In your sound system, when the sound is more demanding, sending power to each specific speaker can produce sound that feels less constrained.
Another benefit to this setup is that it gives you the option of buying multiple amplifiers to power your speakers. That way you could look for amplifiers based on sound quality, without having to worry so much about the amount of power the amplifier can produce. The process of bi-amplifying your speaker setup is almost identical to that of bi-wiring.
The only difference is that after you have two sets of cable coming from each speaker, you attach each of these sets of cable to its own set of binding post on the amplifier or to different amplifiers if you want. The differences offered by these solutions may seem minimal to many listeners, but true audio enthusiasts could find one of these techniques well worth the extra effort. So if you have the right hi-fi components, you can try out bi-wiring and see for yourself. However, it is important that the hi-fi components are designed for this: The amplifier must have at least two connections per speaker channel.
The loudspeaker must also have the appropriate connections, as shown in the picture:. On the picture, you can see the back of the Ultima 40 Mk2. The small gold-plated metal clamps are the speaker bridges. You can find these on the current model of Ultima They are the standard and are always installed so if you want to do bi-wiring you will have to remove them. But even here there is room for improvement for the HiFi fan.
Although, as with bi-wiring, no actually measurable difference can be determined, high-quality cable bridges are still very popular. A cable bridge is basically nothing more than a very short HiFi cable that is used instead of the speaker bridge.
These are mostly high-quality cables, usually, gold-plated connectors are used. As is so often the case, the opinions of hi-fi disciples differ, but many experts believe that a good cable bridge would make a noticeable difference in sound — there is talk of a significant improvement in the sound, of more brilliant highs and more powerful mids.
The market for hi-fi cable bridges proves that these opinions cannot be completely taken out of thin air. These are available in a variety of different designs and price ranges.

Therefore they do not traverse the hi frequency cable. Aerobat , Aug 30, Location: Eastern Tennessee. The key to the point in the original post wording is that he says " The energy being transferred is changed. It is truly basic electronics. And explain why some hear differences and some don't. Assuming they've actually experience trying it and not just using internet folklore for their "knowledge".
CoolJazz , Aug 30, Location: The Cascades. I've only ever read reviews whereby bi-wiring has improved the sound quality however slightly , never how it was detrimental. A large number of charges build up here and these charges have only one function in life and that is to find their way to the black amplifier terminal.
If a path or circuit exists then the charges will start to move towards this terminal creating an electrical current. If during this journey they move through a loudspeaker coil then they can do useful work for us by creating sound.
The amplifier is a power amplifier because within its capabilities it can provide all the current demanded of it by the loudspeakers and still maintain the same potential for current to flow at its red terminal. Note that this current is demanded or taken by the loudspeakers and NOT sent by the amplifier. It can be useful to use every day examples to help us picture how the current flows.
Charges do not flow round the circuit one at a time; rather they behave like a nose-to-tail traffic jam on the motorway. A single charge anywhere in the queue will only move if the one in front moves, so if there is no path to the black terminal for a charge right next to it then a charge all the way at the back of the queue just emerging from the red terminal will be stationary also.
Now imagine the charges provided by the amplifier are divided into low frequency and high frequency ones or slow and ponderous trucks and fast and agile motorbikes in our traffic jam analogy.
Once the circuit is made all the traffic starts to flow out of the red terminal of the amplifier using the single speaker cable, into the red terminal of the loudspeaker where they get separated by the crossover, do the work in their respective loudspeakers and then join back up at the black terminal of the loudspeaker and use the single speaker cable again to reach their ultimate goal — the black amplifier terminal! Note that in the above example both types of current, high and low frequency have to use the same speaker cable.
As soon as the green light is given traffic is already flowing at the black amplifier terminal. It has four terminals instead of two, one pair for the HF network and one pair for the LF network. Two speaker cables are used to connect the HF terminals and the LF terminals to the same pair of terminals on the amplifier. Consider the above circuit before the amplifier provides any potential at its output terminals. Nothing is moving. Suddenly the amplifier gives the green light.
In the HF network are a set of bollards too close together for trucks to get through — only motorbikes can slip through. So in speaker cable 1 only the motorbikes will be moving. In electrical terms only high frequency currents will be flowing in speaker cable 1.
