    Hi there,

    Is it best to wire with one long run thats jumpered or two long runs to each speaker??? Am I right in assuming that the amp is looking for a return from each driver and keeping these seperate is what causes the sound quality difference??? Please see attached bad pic for an example of what Im blabbering on about!!

    Thanks

    Dave

    Hi

    Its worth doing a search in this subject as it has come up a number of times, some people prefer it, others dont, some say it improves sound quality, others dont etc etc

    Its also been an argumentative subject!!

    The best thing you can do is try for yourself and see what you think.:)

    cheers

    Based on your diagrams, the first is not really bi-wired. It is effectively the same as single wired speakers with bridged speaker terminals. The second looks like bi-wiring assumming the cables are twin core ie each has positive and negative runs. You're right, your diagram could be better.

    One thing I can assure you on is Bi-amping makes a difference.

    As to your question, is it possible to try it with the speaker cable you have at present on one speaker?

    I agree, the first one is single wired. However some peple recommend replacing the metal links with two (short) jumpers instead - supposingly improving the sound. But it's not called bi-wiring then.

    Am I right in assuming that the amp is looking for a return from each driver and keeping these seperate is what causes the sound quality difference???

    No, the amp will not "look for a return" and neither do low frequencies flow in the high path nor a high frequency in the bass/mid path. As well they do not just "dissappear" (e.g. as heat).
    Instead the 'opposite' frequency will be blocked by the x-over components in each path.
    This results in a seperation of the low and high frequencies over the entire cable length which theoretically gives a better sound. At least so some people claim.
    Opinions on this are however very much divided and some speaker makers don't even support biwiring like e.g. Dynaudio.

    Which really leaves only one thing to do: try yourself and see.
    You may also consider just doubling the diameter (without opening the link at the speaker terminals), I would be interested in any opinon comparing bi-wiring vs. increased diameter (using the same cable).

    LOL!!

    Thanks for the replies all, sorry about the diagram >.<

    Hmm reckon that I better get a demo of the Q1s bi-wired and not, could save me £50 in cable (unless I go the CAT5 route ;) )
