    Dayton PM-180 Alternatives

    I've been eyeing the PM-180 for high efficiency designs for some time now and I like
    most of the features, the smooth response at least up to about 2K etc.
    Any alternatives from say B&C, Faital etc. that I should be looking at, must have a
    smooth response to 2K, preferably 3K and 94 dB/2.83V preferably 95 or 96, and less
    than $150 each. Need an honest 94 dB/2.83V or better.

    Liking this very much but not sure if I'm up for slicing them:

    Scanspeak 15M/4624G Discovery, 5.25" Midrange
    https://www.madisoundspeakerstore.com/approx-5-midrange/scanspeak-15m/4624g-discovery-5.25-midrange/
    Scan-Speak Discovery 15M/4624G-00 5.5" Midrange in 4 ohms. The Discovery series offer traditional design, superior sound, a solid construction, and a wide range of variants. Combining these elements - plus a wealth of technical features and finesses - gives our customers the possibility of acquiring a tailor-made Scan-Speak solution with very good performance at a reasonable low price point!

      I do often go for 4 ohms, but I need 6 - 8 for this application.

        The Discovery 5.25" midrange is quite a different driver IMO. 4 ohms, low xmax, high Fs, smaller - Its a dedicated midrange speaker where the PM180 is a midwoofer.

        The Dayton PM series is a bit of a unique speaker, somewhere inbetween a home speaker and a PA speaker. Comapred to PA speakers they have above average xmax, and lower than average Fs, and much lower power handling. There's a lot of PA speakers you can look at, but you'll find most are less capable on the low end but have a lot higher power handling capability. If you're looking for more of a dedicated midrange, from PE there's B&C 6MD38, and PRV 6MR500-NDY. The B&C 6NDL38 is a good contender however is a few dB under your sensitivity goal.

          Eminence Alphalite 6a is quite good and capable.

            I don't need all the volume displacement or the low end, 250 Hz in a midrange enclosure is good enough.

            I'd take the Dayton over the 6MD38 from what I see so far was it tested in Voice Coil?

            Like the B&C 6NDL38 but as you say it is far below the sensitivity goal, really just need a midrange.

            It _does_ need to be smooth.

              Do we have tests anywhere? Factory spec looks okay, but it does not seem to have
              any advanced features, high inductance for example. B&C 6MD38 also seems to have
              much higher inductance than the Dayton.

                I completely trust the specs from Eminence and I have heard this driver on a couple of occasions. Every driver I have tested from them has been spot on and I have done quite a few now.

                    In your price range, you're going to have a tough time finding exactly what you describing. Whether it's inductance, budget or efficiency, you're going to have to budge somewhere.

                      I'm fairly certain that the goals can be met if the PM-180 specs are accurate.

                      What did you have in mind say at any price?

                        The PM180 specs are pretty reliable. Jeff B has measurements too.

                        I wouldn't worry about inductance too much if you're limiting excursion.

The 6MDN44's powerful neodymium magnet reduces driver weight while maintaining superb efficiency, complemented by a short, low-mass aluminum voice coil. An aluminum demodulation ring in the motor circuit reduces distortion.

                          If not, the PM180 seems like your best bet.

                            CAn't use an 8, Dayton is still on top.

                            Thanks to all for the input.

                              That looks like a nice low cost driver but, "Far better driver" what is the basis for this conclusion?
