    Did some quick videos so you guys & gals can hear how they compare in sound, Lol you can hear the poor recording on the first video with the emim, with the polydome you can barely hear it as it's muffled, emims will bring out all the good and bad out of recordings.

    Wow thanks for sharing. The domes for sure have a warmer sound where as the Emimm have a flat and more accurate sound. The domes I recognized the sound signature right off the bat since both my speakers have them. I can listen to these for 8 hours a day no problem. I’m not sure with the emimm. Maybe others can chime in if they are more fatiguing.

    They certainly sound very different, but it is hard to draw conclusions without knowing more about the test procedure: crossover used, level matching, etc.

    Crossed over with a single cap at about 550 Hz, used a single coil that crossed them both over at about 7500 hz, didn't have a coil to cross them over lower (4500 to 5000 hz) I believe the HE-EMIM needs a steeper slope to cut out the highs like it's crossover does in the speakers that it is installed in, if you play both drivers without a coil/choke the HE-EMIM goes higher in frequency, the polydome is slightly louder but I didn't adjust the volume so you could hear the difference.

    Okeeteekid thank you again for taking the time! I've never heard the emims standing alone until now! I have to say I like them so much better than the other Polydome possible replacements in your videos. The clarity is immediately apparent. I do agree with @Bahamayellow about potential fatigue since the Kappas have none it would be interesting to hear your, @okeeteekid , impressions about clarity and listening fatigue using the emim in a complete speaker. It doesn't seem too bad in harshness in the videos. I still think the polydome in its proper enclosure and with its complementary drivers is magical. I doubt I'll be able to acquire anything with an emim so PLEASE @Bobbyd38 PLEASE do the polydomes justice and help us resurrect our failing wonders.

    Excellent videos!

    Thanks,

    Mark K.

    EMIM's sound incredible in the speakers that have them, if you have a good recording you're in for a treat but if the recordings are bad/poor you will hear it, the kappas are more forgiving of bad recordings.

    Can you compare one of the polycarbonate cone mids from the RS-II to the EMIM and polydome?

    btw from the videos, the kappa mid sounds just awful .. thanks for sharing

    I agree, the emims are amazing. It must have been solely a cost thing why they didn't 'trickle down' to the kappa series.
    I thought the Polydome was the best midrange I'd ever heard, until I heard Emims.

    well, emims, and magnepan's magnetic planar midrange, and of course, Magnepan's true ribbon. My pair the 2.5r are a 2 way with the ribbon taking much of the midrange frequencies.
    I also adored the sound of the CLS III, that sound largely got me into this search for perfection.

    Now, everything else (with the exception of electrostats and true ribbons) are an 'also ran' for me.

    Dipole planar drivers are the only way to go.

    I’d take the polydome/emit-r or emit k combination over the he emim/ he emit. This is where I was having trouble on longer listening sessions. Fatigue.

    ? fatigue?

    I gotta say, that's one word I've never used with infinity speakers I liked, and that especially goes for those equipped with EMIMs. something else up the chain that the EMIMs or EMITS are being fed, I can believe.

    fatique?

    wow, those words I never expected to hear from you, dave.

    Thanks for the side by side compare. Kind of eye opening that they are so different but both nice in their own way. This simply reinforces my ongoing troubles passing along speakers that sound a bit different from each other, but are both nice lol. I have the Kappa domes in 6.1's but nothing with the emims.
