    ... speakers/amp are biwired but 'links' aren't removed ?

    Would this damage the amp and/or speakers?

    If so... how would you tell if they were damaged?

    What actually happens 'technically' if the links aren't removed?



    best regards

    Doc.:eek:

    Nothing.

    No.

    You would hear it - distortion, crackling, missing highs etc.

    Assuming you use the same cable to bi-wire (just adding another run of the same) you have technically doubled the cable diameter, i.e. there is no difference between 4x2.5mm2 bi-wired and 2x5mm2 single-wired.

    My understanding tells me that there is no technical difference between bi-wiring or single-wiring (same cable type and resulting diameter assumed).
    Most claims to hear a difference is probably a result of the fact that the entire cable is replaced, which usually also results in a different diameter. That can cause audible differences, not necessarily something which qualifies as better but a bigger diameter results in less resistance and that in return "produces" more bass (compare 2x.075mm2 to 2x4mm2).

    In fact since you risk no damage removing or using the link you can easily try it out yourself.

    Agreed. One good length of cable is going to be better than two poor lengths.
    If you do try to biwire with the links in make sure that you wire everything up correctly. If you wire the tweeter and bass unit out of phase then you will short out the amplifier and probably damage it.

    The point where you will damage the speakers & amp is if you bi-amp. With bi-wireing as stated it will do no harm.

    What I have seen recommended before is to remove the links and replace them with a short piece of speaker cable and then only single wire from the amp. This is claimed to improve the sound.

    Can we afirm this (about bi-wiring)?

    1st: Speakers need to have 4 inputs (2 left (black) and 2 right (red)).

    2nd: The amp/receiver only needs the "normal" two outputs, so any amp/receiver can be bi-wired.

    3rd: Using a bi-wiring cable of 4x 2.5mm2 or a single-wire cable of 2x 5mm2 produces "virtually" the same music quality, on same speakers, same amp/receiver, same brand/model of cable.

    4th: A bi-wiring cable runs a pair (2) of dipoles from the amp/receiver to 4 (2 x 2 dipoles) on the speaker end.
    (2 ------------------------> 4)

    Now a question: What type of connectors (4) are on a bi-wirable speaker?

    Thx and sorry

    1. Yes, your speakers need to have 2 pairs of binding posts - 2 black & 2 red with the 2 red & 2 black posts connected by a metal strip that should be removed for bi-wireing & bi-amping.

    2. Yes again! You twist together the 2 '-' & 2 '+' cables at the receiver/amp end and connect individually at the speaker end.

    3. I would assume so, but have never tried.

    4. 4 cores of cable run in a bi-wired setup as per '2' above.

    So bi-wireable speakers will have 4 binding posts, perhap (but never seen them) 4 spring clips.

    Ok, thx. The question I asked was about what the 4 binding posts were called, but I now know they are Low Frequency Left/Righ and High Frequency Left/Right. Thx:smashin:

    Yeah, heard that before. But similar is claimed about bi-wiring itself. ;)

    IMHO the metal bridge makes sufficient contact and has a decent cross-section, so I can see no reason why changing the wiring on the last 2-3 inches would make any substantial (audible) difference.
