How To Bi-Amp And Bi-Wire Speakers!

What is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but separately connecting that power source to a woofer and a midrange/tweeter on a speaker.

Bi-amping is using two separate power sources (amplifiers) and connecting one amplifier to a woofer and the other amplifier to a midrange/tweeter on a speaker.

How do I bi-wire?
Your speaker must have two separate positive and negative connections (one set for the woofer and one set for the midrange/tweeter). Connect one wire between the positive terminal on the amplifier/receiver the positive terminal on the speaker. Connect the other wire from the negative terminal on the amplifier/receiver to the corresponding negative terminal on the speaker. Remove the jumper straps connecting the two sets of speaker inputs. Repeat this process for the second set of terminals on the speaker, connecting them to the same positive and negative terminals on the receiver/amplifier. Repeat the steps for each speaker you wish to Bi-Wire, connecting them to the appropriate terminals on your receiver/amplifier.




How do I bi-amp?
Bi-amping is similar to bi-wiring, but involves separate amplifiers: one for the woofer and one for the midrange/tweeter. Passive bi-amping involves a direct hookup between each amplifier and the speaker terminals. True bi-amping involves hooking the preamp to an electronic crossover that replaces the passive crossover network in the speaker. The active crossover then connects to multiple power amplifiers.

I have Xavian xn125 speakers. How do I connect them in a bi-wired or bi-amp


Bi-wiring basically works wtih one amp. You need a crossover network and a signal doubler to use two amps (bi-amping). There are many diffent ways to bi-amp (horizontal, vertical,...) This link: - -http://www.soundstage.com/synergize/synergize031998.htm-- explains them all. Bi amping is usually not worth the extra price and complexity when used on smaller speakers.

Bi-wiring does nothing but make you use twice as much speaker wire for the same electrical effect. Bi-amping assumes there are deficiencies in your electronics that must be worked around, again by using more speaker wire and separate amps.

Do some reading on the web about "bi-wiring".

SMCCARTY,
The idea behind bi-wiring speakers is to get the highest quality of sound by getting the sound from two separate sources doing separate jobs. Lower frequencies are harder for an amplifier to produce than higher frequencies. So it is common to give these frequencies to two different amplifiers so each can produce the highest quality of sound. By removing the low end from the top end amplifier, it provides the top end amp more headroom thus reducing the chances of clipping. Clipping can easily be heard from the tweeters destoying not only the sound but your speakers as well. It is common practice in pro and car audio to use separate amps for subbass, low, mid and high; four amps working together to their corresponding drivers (more or less depending on the system and type of audio being produced).

In your case, getting the two different sources from basically the same amp (power supply), would not accomplish the full intent of bi-wiring; it would just make more wiring for the same end result. However still a good thought on your end. Onkyo receivers are great because of their beefy power supplies. Not very many other brands have such strong power supplies. Denon's are close but not equal.

how do i bi amp sx 1250 to get both channels of each side to work together


you are actually not bi-amping the unit, you are bridging the amp. this really only works as long as all channels produce equal power. next the bad news is that typically home stereo amps are not wired internally to bridge channels.

bi-amping a speaker refers to connecting on channel to the highs and on channel to the lows. the receiver would need to be be able to process the outputs via a crossover network to split the frequency range in half so the appropriate frequencies went to the correct speaker.

bi-amp


After examining a picture of a 5802 ( I have been servicing adcom for over 20 years ), these are not bi amp posts, but bi wire posts.

Bi-amp means that 2 amps are being used, one for highs, one for lows. This means that you have no crossovers in the speakers, instead, you have an electronic crossover between the amps and the pre-amp. The highs and lows are separated in the electronic crossover. One amp handles the lows, one handles the highs.

Bi-wire means that you have the crossovers still inside the speakers. The amp handles the full range of music ( highs-mids-lows ). Different kinds of speaker wire produce different results. If you have bi-Wire terminals on your speaker, they come with shorting wires, that tie the tweeter + to the woofer + on the back of the speaker, and the tweeter - to the woofer - . When the shorting wires are removed completely, you have now electrically separated the tweeter and woofer from each other, while maintinaing the crossovers ( inside the speaker ) for each.When this is done, you can now bi-wire the speakers and amp, and use different kinds of wire for the lower frequencies and the upper frequencies, depending on your ears ( everyone hears a little differently, thats why there are so may makers of components, and wire ).

Why do we have crossovers?.....the tweeter voice coils ( the things that make the sound ) are made of hair thin wire. This wire cannot handle much power and if you were to put bass in to a tweeter, you would burn the tweeter out almost instantly. A tweeter is a very light, fast moving device which can react very quickly to high frequency sounds ( symbols, triangles, guitar strings....). Woofers are more rugged. They have voice coils made of heavier wire and are designed for larger movements that Bass demands. Subsequently, woofers aren't very good for high frequencies because they are slower devices.

So what do we do ?.....Keep the lows away from the tweter and the highs away from the woofer.....thats the job of the crossover.

In the event that your speaker has the crossover OUTSIDE the speaker box, you should check ( as always ) with the manufacturer of the speaker to see how it can be changed to suit your needs. Remember to always read and follow your owners manual. Good luck....Rob
