How to Use Bi-Wire and Bi-Amp Stereo Speakers

Spend less than 20 minutes enhancing speakers for enhanced sound

Those who are serious about sound tend to consider all the possible ways to customize speakers to achieve the perfect sound. Small increments can certainly pick up, which often turns a good system into an excellent one. If you have the right kind of hardware, you can choose to perform extra performance through bi-wiring and / or dual amplifying stereo speakers.

How to bi-wire

There are some potential benefits to bi-wiring, although this is not guaranteed due to the subjectivity of sound. But before you start, make sure the option even exists. Much newer, often high-end, speakers offer a bi-wiring / amplifying connection. These models have two pairs of binding posts on the back of each. Thus two- pivotable involves the connection of two lengths of speaker wire to each speaker, one to the woofer section and the other to the midline / tweeter section.

Bi-wiring a speaker can be a relatively inexpensive way to improve the overall sound quality. Ideally, one would feed two identical lengths (and type and size) of two-conductor wire to each speaker. One wire handles the tweeter and the other the woofer for each speaker. Sets of bi-wire speaker cables can be purchased and used for the same effect. What bi-wiring can do reduces the negative effects of the impedance differences between high and low frequencies moving through a single wire. And having two-wire speakers with separate wires can also help reduce the interaction between the two signals and thus improve the overall sound quality .

  1. Look for the right terminals. Not every speaker can be bi-wired. A speaker must have separate terminals (two pairs of binding posts) for the woofer and midrange / tweeter. Sometimes they are marked with the designation ‘high’ and ‘low’. Sometimes they are not marked at all. If you are unsure, it is advisable to consult the operating instructions for further information before attempting to contribute the speakers.
  2. Remove the shortlist. If you used your speakers normally (single wire), you may have noticed the small accessories that connect the positive and negative terminals. Once you have eliminated this, the speakers are ready for bi-wiring. Be sure to remove them before connecting the speaker wires to prevent possible damage to the speakers or amplifiers.
  3. Connect the wires. Plug each pair of cables from the amplifier / receiver to the terminals on the speakers. Since the cables are identical, it does not matter which wire pair goes to which transitions. If you happen to use banana plugs, make sure the connections allow you to attach a wire from the side. Otherwise, you will be left with endings that go nowhere.

How to strengthen

Now if you really want to go the extra mile, dual speakers can offer a different level of customization and control over sound quality. However, this can be a more expensive option, as it often involves buying separate amplifiers . Some multi-channel receivers have multiple amplification channels, eliminating the need to purchase new equipment. But the advantage of dual speakers is that it allows the system to further isolate the frequency zone with separate amplification channels. This way, specific requirements can be met without overworking the hardware and can lead to increased distortion.

For more noticeable results, some recommend using an active crossover setup rather than the passive transition built into the speakers. The previous method divides the signal into high and low frequencies before conducting it in separate amplifiers leading to the speakers. The latter sends the full range of signal to the amplifiers, which then forces the speakers to use internal filters to block the appropriate frequencies. One disadvantage of bi-amplification (besides the additional cost of amplifiers, crossovers and cables) is an increase in cable connections and system complexity.

  1. Connect the high frequency first. Assuming you have already connected all your speakers to two devices, disconnect the cable clips that are plugged into the source. Connect it to the amplifier designated to handle all the high frequencies.
  2. Connect the low frequency. Now repeat the above step, but with the cables and amplifiers designated to handle the low frequencies.
  3. Choose passive or active bi-amplification. If you are going with passive bi-amplification, connect both amplifiers to the source output. If active bi-amplification is your goal, the two amplifiers will first be connected to an active crossover unit. Then connect the active transition in the source output.
