    I would hope that the AMT2-4 would be good to at least 3kHz or even less, provided the distortion is still ok there since it is a smaller AMT. I personally wouldn't want to crossover above 3kHz with a midwoofer of that size even if the response was ruler flat, simply due to the narrow directivity (beaming), leading to a speaker that may be difficult to create that seamless interaction between mid and tweet, and with a smaller sweet spot.

  • I used the 2-4 to about 3.3k with a 4th order electrical. Distortion started to rise pretty quickly at 2k iirc. 
  • I was just informed that we only have 2 left.
    Solen is still running a great tweeter sale.https://solen.ca/products/on-sale/

    I've had good results with large format tweeters crossing to mid-woofers up high.  I surmise that it's due to the tweeter's falling off axis response matching the mid-woofer's narrowing response.

    Also note we're not talking about head in the vise narrowing directivity, a 6 inch piston, -6 dB angle is still over 60 degrees at 4K.

    I've got some Wavecor tweeters from Solen, but if Wolf is using them I have to do something else :)

    I assume the CP is on clearance because it will be discontinued?

    I'm told that they are not discontinuing the model but there will be changes in the coatings. The CP has three different layers and each layer coating is different. It looks like they have reformulated the coatings and will be using two layers on the new ones. I don't know yet if it will be still called CP or some new designation.
  • I have the P-8, not the CP-8.

  • May try a TL tweeter.

    Get them while you still can! A few weeks ago, TLabs basically closed its doors, according to Cristian Nedelcu himself.

    Out of business if you read Pete S's last post on PETT

  • TL tweeters have been on sale at Solen for quite some time. Get them while you still can!

    You won the Cap Pack? NICE!
  • I did - pretty sweet bonus, actually. Also got a bag of resistors. I am a sucker for collecting crossover components.

    Nice looking caps, too. Ill post a pic in a bit.

    Congrats!
    For some strange reason we sell more of those to Europeans than Canadians or Americans.
  • Nice score JR.  I like collecting round shiny things and can't seem to pass up a deal x-o parts

  • Well if there's anybody certain to use 30 crossover parts in the next 24 hours it's JR!  Now go buy the Maynard Collection!

    I got a sneak peek at their 8'' Alu/Ceramic drivers today and asked if I could take a picture. The picture doesn't do it justice. The cone is a warm black and the frame is a little different that the others. Just to confuse me even more, they have 3 versions of these drivers. No specs yet, but here's a boo.

  • Those a pretty ok looking, I like the the look of the inverted dust cap better. Looks like a Klipsch but without being ugly orange.

  • Here is the 7''.


  • That matte black looks good.  I got my CPs today they remind me of mini usher woofers.

  • Like 'em, please get them....!

    Here's the little feller. 4.5'' R120-ACB-08 & R120-RCB-04

  • re: 4.5'' R120-ACB-08 & R120-RCB-04

    Good size for a pure mid, and I know the motor will be strong.
    Looks like this are Alu cones?  Any chance of Paper or Kevlar/Paper cones?
    But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!
  • edited January 2018
    They have a few versions of paper cones that are proprietary formulated. Some are made in Canada and some are made in China. I think this 4.5'' is made offshore. There is also a woven carbon hybrid in the 4.5'' that looks interesting.
  • I see allot of people comparing the Rival paper driver to Usher. Well, I had a little time to kill before the kids get here and thought I’d play a little. This is not gospel but here is a general comparison between the Usher 8945P and Rival R176-P-08.  Doesn't really mean much, but fun to do.

    Everything about these photos says Wavecor to me. The motor looks exactly like Wavecor balanced drive, and even the label on the motor, you could literally replace the Rival logo with Wavecor. This is good news, as the retail cost a Wavecor WF182 is a lot more than the sale price of these Rival units.

    I've been thinking of what to build with my pair of Motus tweeters. Realistically I want to use the nice underhung Motus woofers, but they carry a pretty high price tag, or do I cave in and buy a pair of the Rival drivers at the current sale price? Decisions, decisions...

    Here's some photo of my WF120 for comparison.

    And the motor:


    Have you ran any measurements on those Wavecors?
