    Ya, I think I'm going to snag them. I wish I could get my Unibox working so I could sim an enclosure. (hint-hint)
  • I think they'd be a great midrange.

    I'm thinking small TM, maybe computer speakers.

    The Fs is pretty low, but we don't know xmax yet.
    So far, I agree with Wolfie - nice mid for some 8 /10/12 inch woofers.
    Those Rival designers really know how to get a flat FR with low distortion. Nice.
    Don, Donno, or "Hey you" all work for me, But never "Mr Johnson"

    Xmax is 5mm. I don't have any plans for a 3-way. If someone has future 3-way plans and thinks these will help fit the bill I will offer them to you.
  • 5mm is pretty good for 5" woofer
  • low distortion good upper extension looks like a great use for a nice planer or ribbon tweeter to make a hifi desk monitor. 5mm xmax should make it work well as a TM and give you a slim box that will increase the ever important WAF.

  • WOW! I love these little guys. I've got them playing open sitting on top of my Celestion 44s. Yes, I'll be keeping them. <3

  • Darn it! I can't keep them. If anyone wants them they are for sale $80 for the pair.
  • Darn it, if it was 4.5" I'd jump on it. A bit large for a 3 way mid.
