  • Using Different Speakers



    How good are the internal speakers of a Hammond M101? Yesterday, I freecycled a pair of Wharfedale 70 speakers built in the early sixties, and they have awesome tone with a really full low end, sort of like organ speakers. So, then I thought about unplugging the internal speakers of the Hammond and sending the signal to the big Wharfedales....</p>

    is it worth it?</p>

    Well, I'm not an expert, but I ran my Schober Recital Model through a pair of Wharfdale speakers (with 15" woofers) for a while back in the 1960s. I never had a problem, as Wharfdales are rated for quite a lot of power and the sand-filled walls of the cabinets really stifled any resonances. I'd guess it would make a difference which particular Wharfdales you have and what their power rating is; also how low a frequency is available to drive them.</P>

      It's certainly worth a try. Just keep in mind that the frequency response may be different on the Wharfdales vs. Hammond's internal Jensens. It may make the keyclick and/or crosstalk louder, if it has good high end. But I'm willing to bet that you'll like that, since you like the dark gritty vintage sounds.

        Speakers are very subjuctive. It all depends on what you want it to sound like. I have a custom Digital Pipes organ. Every voice goes through two to 8 separate channels (tibia has 8, viol 2, others 2 to 6 channels). Depending on what speakers are connected to the viol (as an example) gives a great viol, but different qualities. The only thing I can say is try different speakers and stay with those that give you the sound you like. </p>

        Just like pipe organs are voiced per the person in charge of the organ, the style of music being played and the venue..... select speakers that fit your preferences for voicing. </p>

        I really think there is no right or wrong speaker. For me, one set of speakers gives a bright principal and accentuates the chiff (nice for classical playing). Other speakers accent the fundamental and there is no chiff (great for theater playing). So use your ear and pick what you like.</p>

          Also check that thetotal impedance of what you're using is close to what the Hammond's amp expects to see.</P>

          It's not what you play. It's not how you play. It's the fact that you're playing that counts.

            Whoa whoa whoa... .he's absolutely right... you see... this M101 is basically a large thermonuclear reactor......</P>


            andyg is right David Eugene... you need to find out what the impedence of those subs are before you hook them up... I'll assume their 8 ohm but it's always wise to double check with a multimeter *even though the reading will be in resistance and not impedance, it will be close enough*. In fact.. if you could stalk the Theile-Small parameters for your subs or derive them manually *always a fun project*... you will find that the value you measure using a multimeter will be the same as the Re value in your specifications. Also... when taking this measurment.... be sure not to disturb the cone or suspension/compliance system as you will alter the resistance by moving the voice-coil through the fixed magnetic field *magnet*..... as a rule of thumb in having worked with car audio for over a decade... a normal 4ohm driver will read somewhere between 3.3-4.4 ohms.... so a good rough and ready way to give you an idea of the nominal impedance is to measure the DC resistance across the terminals and multiply your result by 1.3 ;)</P>


            Good luck :))))))))))))))</P></BLOCKQUOTE>
