  • New Dayton 6.5in Drivers - GF180-04/08 Glass Fiber

    Just noticed new Dayton drivers are in stock. 8ohm, 4ohm.

    OOPs !

    That Vas value MUST be in liters ...
    (about 0.55 cu.ft.)

      15.5 cu ft.

      The cone would fall out if you turned the driver over . . .

      I laughed out loud!

      :D

        I guess yellow glass fibre (fiberglass, lol) is out of fashion.

        8ohm response looks good except for the peak out b4 5k.

        really good price

          ^ Definitely.

          Making the Wavecores look . . .

            I just wish the sensitivity wasn't so low - seems to be the norm these days . . . but we have cheaper class D & T amps . . . 200 Watt class D for the mids!!

              The advertised response of the 4 ohm looks like they will require less BSC than most drivers. They would likely end up 80-82db when implemented, which is pretty much typical for 6-7" 2-ways.
              Don't listen to me - I have not sold any $150,000 speakers.

                But the listed specs say the 4ohm has a sensitivity of 90.7db...

                  . . . at its peak break-up mode - the rest of it is around 84 db or less . . .

                    "peak sensitivity" would be more accurate, that value is a sad joke if you define sensitivity as the average sensitivity through the useful passband. Using the metric PE have used for this driver, the RS180-8 is a 98dB sensitive driver.

                    PE needs to ditch the mismash of metric and imperial units. When all other units are in metric, use metric for volume as well. You'll find this will match up with any competent spec sheet.

                      Typical of an 8 ohm 2-way. To be fair, these drivers are a on the high impedance side, the 8 ohm is really a minimum of 8 ohm, and the 4 ohm is a minimum of 4.4 ohm.
