    Bi-wiring La Scala's

    in Technical/Restorations

    Posted

    Anybody having experience with biwiring - not bi-amping - La Scala's?

    Is there any positive effect that is worth the effort?

    Can I blow the midrange/tweeter if I feed them bass frequencies directly?

    I'm using a 2x2W SET amp.

    Thank you for any efforts,

    La Scala wiring diagramm

    in Technical/Restorations

    Posted

    I was satisfied with the sound I get from my La Scalas for quite a while until

    I checked the wiring of the drivers after a phasing test via phono indicated improper phasing.

    I found the midrange driver on one speaker to be connected just the opposite way than that on the other speaker.

    The red cable from the (AL-3) crossover was connected to the right terminal (when looked from the rear of the cabinet) of the midrange driver, the black-red cable goes to the left.

    Both other drivers are connected red to left side and black-red to right side.

    Reversing the cables on the midrange (now all drivers in both speakers were connected red to left side and black-red to right side) had a negative effect of the system's sound so I returned to what I had found.

    I now reversed the cables on the other speaker's midrange to get identical wiring in both speakers and the effect on the sound was positive - better staging of voices and instruments.

    Just to make sure: Does anybody have a wiring diagram or a description of the wiring of La Scala's drivers as intended by the maker?

    Thank you for any efforts.
