Repl. 6R Spkr w/ 8R

Discussion in 'Electronic Design' started by Luke Stafford, Jun 7, 2008.

  1. I have two large bookshelf speakers with blown woofers. The label on
    the speaker enclosure says it is "6 Ohms". Can I replace the 6 Ohm
    woofers (can't find any) with new 8 Ohm ones of the same size and
    quality without affecting the sound? There are rwo smaller speakers in
    each enclosure and a crossover network.

    Thank you for any advice.

    ** The original woofers would have been of nominal 4 ohms impedance
    ating - the 6 ohm figure is a weighted average impedance of the whole
    system over the audio band. 8 ohm woofers may indeed be OK to use - but it
    all depends on their sensitivity ( dB /watt/metre) and how the x-over
    network is configured.

    The gotchas are that the new woofers may simply not loud enough to match up
    with the other drivers and/or the system impedance falls well below 6 ohms
    over some band of mid frequencies due to series resonance in an LC network.

    You could probably use any similar looking and fitting speaker with
    only minor changes in the sound.

    BTW the woofers are not 6 ohms, the complete unit is.

    They would do so much less harm.
