  • Rs125-8

    Has anyone measured the 2.83v sensitivity of the RS125-8? Is the spec sheet accurate at 87db?

    Also, has anyone compared the RS125-8 to the Zaph ZA14W08 or the SB12CAC for midrange use?

    Thanks everyone!

    Dayton posted specs are usually pretty accurate, at least they've matched up well with what I've personally measured.
    It's been a while, but the RS125 was put into quite a few projects as the midrange. The RS100 also works very well as a midrange, so does the RS150.
    As a mid on a wider baffle, crossed at or just above the baffle step, you should expect the stated sensitivity. And once relieved of bass excursion duties, they render the midrange in a pleasing manner. Dealing with the cone resonance on the RS125 is very easy.

      Typically, 8ohm driver specs should match the FR curve pretty well. (You really need to look at/sim the FR curve to determine the proper answer to your ??)

      Where things have gotten kinda goofed up (AFA Dayton's/PE's specs go) are w/ 4ohm drivers where the "1w" rating (which is only 2.0v, I believe) has gotten mixed up w/the 2.83v rating (which is really 2w - into 4 ohms).
