Another strangling from Rival

edited March 2019 in DIY
I received some initial info about two 5.5'' drivers from Rival that look intriguing. It was suggested to me that the specs are close but may not be exact.
This cone is coated Kevlar/Pulp. 39mm VC - 120mm magnet  :)

Revc=  3.7  Ohm

Fr=  42.000  Hz

Sd=  108.000  cm²

Vas=   14 L

Cms=    1.16 m M/N

Mms=   12.20  g

BL=    6.46  T·M

Qms=    6.716

Qes=    0.287

Qts=    0.275

Le=  0.085mH

SPL=  90 dB (2.83V/1m)

Linear excursion=  ± 4.5 mm

Continuous Power = 60w (IEC 268-5)

    Strangling? Not sure what is meant by that. I like the coated carbon fiber!

    Strangling meaning they don't usually release these for public consumption. :) I was surprised to get this yesterday. I'm waiting for the fr etc.

    +1  that coated carbon fiber looks greats.

    I'm listening to the coated carbon now, open air. It sounds very smooth with Eva Cassidy playing. I'll find out how many he has and willing to let go. :)

    Here is the 7'' but no specs yet. There's also an 8-3/4'' one.

    That makes more sense.. 'strangEling' not 'strangling'

    The 8.75" one sounds interesting too!

  • rjj45rjj45
    Nice high QMS on the 5.5 inchers. Promises great detail.
    But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!

    Gowa! Get out of my head!.............oh well, just let me know when they're available. 😉
    ............. could you hum a few bars.

    I'm interested in the CF as well.

    R152-CFC-04 - 5.5'' coated carbon weave

    If anyone is interested in these drivers contact me at rhythmaudio@rogers.com
    Warning: these are not cheap. :)
    These will be gone in no time.

    Resistance is futile..... really.

    Wow, that's a smooth FR, no break up?!
  • jr@macjr@mac
    Welp, guess I needed a couple more Rival drivers. Pair of the 5.5" CF on the way. Sexy bitches from the pictures.

    Wish I could have swung a quad of the 7" CF as well, but I have a lot of 7" drivers around as-is so... 

    I can finally start building pretty soon, have to clean up my yard - what a fucking mess this winter left behind. 
    I have a signature.

    First look-8 3/4'' R223-cfc-08

    The 5.5'' R152-CFC-04 sold quickly as expected. Just one pair left. :)

  • jr@macjr@mac
    I'm going to tell you right now I want a pair of the 8".

    Reading my mind....... curse you!

    Same, I want a set of 8's
  • GowaGowa
    The 7'' R176-CFC-08 carbon drivers sold out very fast. :) I'll have to check on the 8-3/4'' to see what's available. I'll be at the Rival facility on Tuesday. B)

    Is the 8-3/4" actually larger than what other manufacturers call their 8" ? Or are they measuring differently? I know some of the dayton RS for example drivers claim a large diameter compared to their actual SD

    Many are measured to the outside frame edge, not the true cone diameter.
    ............. could you hum a few bars.
  • GowaGowa
    Rival measures theirs by the frame diameter.

    Here we have the 5.5''  Kevlar/Pulp coated driver. It doesn't look as good as the carbon one.
    1/24th. Opinions?

  • CivitCivit
    Those still look pretty excellent. I didn't know Rival was making such superb midrange units; these look fantastic.
  • GowaGowa
    Rival also has a series of traditional type paper drivers. They use either carbon fiber or Kevlar fiber in their pulp formulas. 
    Paper 5.5''

  • 6thplanet6thplanet
    ....so where's the 8's....🤔
  • GowaGowa
    We are working on the 8's but they are not a priority for me. More people want small mid-woofers, so those will be first place. Starting in May we should see a variety of 5.5'' drivers and then the 8's and also working on the 10''.
