Wiring up a pair of speakers with 4 speaker outputs?

Hi,

I was thinking about it today. Are you able to bi-wire a speaker by using two different left (for eg) speaker outputs on the amp? If so what sort of affect would this have to the system?

I think you're talking about bi-amping?

So your saying using Speaker Output A for the highrange drivers and then Speaker Output B (on the same amp) for the lower range drivers?

Hmmm dunno :rolleyes:

if the speaker didnt have the four plugs (inputs) then it would sound no different as the two separate signals would be coming together right at the speaker itself ?

One of the reasons to do that is to bypass the crossover circuit, so the low and high frequency parts of the speaker have their own independent signal source that hasn't needed to be split.

if you are talking about an amp that can drive 2 sets of speakers and using them to bi-amp a single set i was told years ago that it wouldn't work - something to do with doubling the impedance. separate amps are needed for bi-amping.

er, i think.

Like this below image to make it completely clear.

if you are biamping from two seperate channels then there is a definate benefit. if you are trying to do it from 'speaker a' and 'speaker b' then you will hear no improvement as they are both the same channel in the amplifier. in other words speaker a = speaker b, its just a way to add a switchable set of extra speakers to an amplifier.

I guess in that method you are effectively just bi-wiring the speakers?
