        That Vifa/Peerless semihorn silk tweet I noted above can do 99 and one may still need to tone it down a little for the 15" Pro Kappalite.

        Listening to a recording of speakers is something I have zero experience with...I have no idea how it translates, how much of a difference the mic, positioning, SPL (how closely do they need to be matched?) come into play. That's where my distrust comes from.

        I meant the above as a compliment. Having heard the RF7 yourself probably helps, at least it would give me something to correlate what I'm hearing.

        I honestly never would have thought there was much of value in a recording of speakers until your post. That's why I initially asked if you were being sarcastic...it was true curiosity.

        My bad for not trying to be more clear since you don't know where I'm coming from.

        Don't worry. Yes. It's not the same thing as the real deal. But it gives one some idea, specially if two speakers are recorded the same way and one is familiar with one. IMO.

        I sold truckloads of Forte 2s back in the day. Never heard a F3. As an option, I bet if you picked up a used pair of 2s you could hotrod those to meet or exceed the 3s. Paul Klipsch was a genius.

      Today I read somewhere that class A was the sex cuz no crossover distortion. Note the operating region of a device is approximately linear.
      1. ultrabike
        ultrabike
        So no, there is still distortion. Particularly compression can occur. So even in the absence of cross over distortion, the system can be made more linear with some negative feedback.

        I figured you might find it useful, it’s too much of a pain in the butt to mess around with clip leads and external loads...and it also allows you to use a headphone as a load. We use these boards internally, so I figured we should build some up and share them. Marv and AtomicBob got boards too.

      Seems 2i2 DAC outputs are good, both balanced and unbalanced (away from clip). Headamp is mediocre (as heard). More SR1 learning needed.
      1. ultrabike
        ultrabike
        Looking at 100 dB THD+N balanced full scale, and about 98 dB THD+N unbalanced a bit shy of full scale (onset of clip). Headamp is more like 77 dB or so. This correlates well with what I heard. I drove higher end headamps with the 2i2 DAC, and it becomes apparent that the headamp is limiting performance. Somewhat of a haze. Lack of clarity. It's not that bad though considering all that one gets.

      RS28F-4 + RS180-4? Appears to be almost perfect. Too good to be true. That tweeter is no longer around?

        Just gave it a try: crossing the three tweeters. It is possible but I needed 3rd order all over, and not feeling confident about it. Proly best to keep it RST28F-4 + RS180-4, or if 3-way go for the 2" midrange.

        How much do you really gain from the ND13FA-4? 16KHz is about it for me, so an RS180-4 & RST28x-4 would be really tempting. 11 litre sealed box for use with subs, and there's a shallow faceplate for the RST28x-4 that's only 3 1/4" tall, so could make a center channel with vertical alignment that's only 12" tall. Avoids the comb filtering of an MTM center

        It's not high frequency extension what you gain with the ND13FA-4. Is dispersion characteristics. A larger sweet spot (45 degree +) and a more omnidirectional response all the way to 16 kHz. In general, I don't like MTM configurations. But for center channels and practical considerations, sometimes it can't be helped.

      Man, that RS180-4 driver is all kinds of awesome in a 32 lt. No need for a sub with that. Salivating on an Amiga like build.

        Yes. The DX25 can produce SPL down to a 1.5 kHz, but it is not recommended perhaps due to distortion and maybe resonant impedance. I did look at the RST28F-4 and it is the top contender for a 2-way design. It is not straight forward. The RS180-4 almost begs for a 3-way design with an RS52AN (ZDT3.5). But that would require some distance for driver integration. Still thinking about this.

      3. ultrabike

        All that aside, I took a look at what can be done with an RS180-8 vs. an RS180-4. I like the RS180-4 a lot more than the RS180-8. It has lower compliance volume and can go down to 26-29 Hz with the COTS enclosure by Parts-Express cleanly. It fits like a globe and an incredible deal.
        Sep 27, 2018
      4. ultrabike

        Again. I agree with @Ardacer that the new RST28F-4 is the way to go for a 2-way design. With all the compromises, that and switching to the RS180-4 with some slight crossover modifications would likely yield a small step over the Amiga and Core 2-way. I like that better than the TRS-80. And it may integrate and play better than even the ZDT3.5. Hell, I'm actually thinking of 3-way with RST28F-4 + TD20F-4!
