So half the speaking length... David Ilvedson, RPT Pacifica, CA 94044 Original message From: Erwinspiano at aol.com To: pianotech at ptg.org Received: 1/3/2008 2:30:47 AM Subject: Re: duplex position Hi Frank Although you are correct about this for many pianos, the Steinway B's rear duplex string length doesn't follow this. it's an octave higher Dale David, et al, I cannot speak to the specific make, model, and era of your piano, but typical of pianos with this type of duplexer, the distance from the back bridge pin to the duplexer at note 88 is equal to the speaking length. One can go a step further, and after stringing, nudge the duplexer in or out, to "tune" the duplex length to sound in unison with the speaking length at note 88. Whether one believes that "tuning" the duplexer is effective, it was probably the design intent, if you find that the original position of the duplexer suggests this relationship between the duplex length and the speaking length.
