    I ask you having foolishly replaced the 2213h with the 123a-1 in my 4312 first series (with original crossower
    )What should I do ? reverse the wires behind the 123a-1?
    to have a right crossover ?

    thanks for the help luigi

    If the only difference between the two woofers is the polarity, no big deal. Just reverse the wires at the woofer.

    [QUOTE=Mr. Widget;439851] Se l'unica differenza tra i due woofer la polarit, non un grosso problema. Basta invertire i fili del woofer.

    I hope to definitively remedy the mistake of replacing the two woofers

    Very thanks Mr Widget.....

    Yes...Just reverse the wires.

    That said...the 2213H, if in good working order...is a superior woofer to the 123A-1/2212. If someone told you otherwise, you were lied to. The ONLY thing that might make the 123A-1 "more valuable" is the AlNiCo magnet, which is also removable from the frame, and which carries a mystique that ceramic does not have, but the ceramic 2213H is a better performer.

    questo... la 2213H, se in buone condizioni di funzionamento... un woofer superiore al 123A-1/2212. Se qualcuno ti diceva il contrario, ti hanno mentito. L'UNICA cosa che potrebbe rendere il 123A-1 "pi prezioso" il magnete AlNiCo, che anche rimovibile dal telaio, e che porta una mistica che la ceramica non ha, ma la ceramica 2213H una performance migliore.

    thanks for your answer,
    yes in fact and 'went so' I advised to replace the 2213h with 123a-1/2/3 in alnico because' better from a sound point of view so' also the 5/12 with le5/2 in alnico ...
    In addition 'without making any changes to the crossover,
    In practice now I have a 4312 hybrid .. which I believe has no one...
    unfortunately I can't go back buying the original drivers would be too expensive for me.
    Thanks again for the support
