  • Thanks to a heads up from Leon, I bought four of these this morning:

    Should be a pretty solid foundation for a tower speaker. I don't think they will play as low as the Eclipse woofers in the Taiga, however. They are probably at least as clean, though. They may even have better cone control - a known issue in the Eclipse drivers (which is why I tuned as low as I did in the Taiga - but that is another story).

  • Looking forward to your data on these. I've been thinking about them.
  • Looking forward to seeing some actual measurements. For the price couldn't go wrong.

    I am remembering ProAc clones and D30 model.
  • Every year I say 'this is the last build I'm doing' and every year something comes along to pique my curiosity and creative juices.  This did it.  Thanks Roman for making these available!  I PROMISE to have a design ready for 2018 Iowa DIY.  
  • BTW it looks like JR's Rhythm drivers are now OOS.  The link is dead.

    Looks like the price may be gone for now, but the woofers not for long.

  • I was able to load four of the RAD woofers in a cart and get to checkout.  $40 for shipping to Chicago. Not buying them though.......Really don't need any more drivers.  Really.  No, really.
    My signature goes here
  • Apparently, I *did* need more drivers. Le sigh.

    If I ever get a chance, I am going to build a metric fuckton of speakers, though.

  • Is Rival acoustics and Rythm Audio one in the same?
    http://rivalacoustics.com/woofers.htm
    https://rhythmaudiodesign.com/

    It looks like they carry the same drivers 
  • Scratch that .... It looks like Rival caters to distributors and not individuals.

    I succumbed to temptation and bought two this morning.  Should be fun!  Sale ends 12/21.

    Dang it Ed, your order is all it took to break me down.  I grabbed four.
  • We can all measure our drivers and see how consistent they are. Did anyone else buy any ?
  • Leon - are there any plans to sell the 5" model via Rhythm? 
    I have a signature.
  • OOPS! I hit that darn "purchase" button.  :s
    ............. could you hum a few bars.

    Rumor has it that they could be available in the Spring. YIPPIE!

    GRT is getting a waveguide as an option. It will be slightly larger diameter. 110mm.
    I will CNC these out of Walnut, Mahogany and a couple of other woods.
    The screw holes are not drawn yet. The guide will most likely attach directly to the face plate with the gasket in between. Mounting screw holes  on the guide will line up with mounting holes on the faceplate.

  • I would like one pair..... Would this allow for the XO to be at 1800? I am looking to cross over to an 8" driver
  • You can cross it at 1800hz now with a high order. just stay within safe voltage/f/

    I am not a big fan of crossing that low myself tho. If it's a conventional design, I'd throw in a midrange. Crossing to 8" driver would be my way of pairing with GRT if it's a high sensitivity build or a full range/ribbon concept.

  • 95+ db sensitivity, 8" mid, 15" woofer 8ohm nominal design. maybe 2k, but i run into directivity issues. not many tweeters that do so well.

    I was considering the satori neo (be / non be) which also has 96db, but somebody on PE said it can't go below 2.5k. Else I'll have to go to a uber expensive Mundorf AMT or maybe the big RAAL ribbon.

    I didn't like the big RAAL below 2.5K either.
  • hmm... need something that can cross to a 8" mid at 1800 or so at 95-96db
  • Horn loaded compression driver?

    I agree.  They're not just for pro sound...

    Would the Bozhen do that?
