Namaskaar Janos 🙏 Greetings from Bhaarat (India)! First, my sincere gratitude to you for sharing your realistic insights and experiences on high fidelity speakers. Being myself given to minimalist design, single wideband driver speakers hold a great appeal! I do have a question regarding whizzers. Do whizzers integrated with the larger cone imply a mechanical crossover? What would be the order of such crossover? And does this integration/transition between the two cones cause a phase shift around the transition frequency like it does when using a capacitor for a tweeter? Your guidance would greatly help a novice like me! 😊 Thank you in advance! 🙏 Warm regards, Sujat
Did you ever tried an Abacus Amp (made in Germany, Nordenham)? I´m using them after I tried a lot of others. I use an old one Abacus-Rieder 60-120 from the 80th an a newer one Abacus 60-120c, the old one with Phönix-Klangsäulen and the newer one with AMT1D. I think, it would be an experience to hear such an amp with a single driver. BR Roland
@@realworldaudio Oh, your are living in Hawai? Such a beautiful place. You can goole it with abacus-rieder or look to the site of abacus-electronics to see, what they make. It´s an interesting way to build amps. I have two of them, but not the newest ones, one from the 80th and one from about 2013.
Hallo Roland,…ich hatte den kleinen Ampino von Abacus in Kombination mit einem Lowther PM 2 A. in einem Acousta Gehäuse. Im Grunde ist die Schaltung des Abacus ja einen Röhrenschaltung, nur eben ohne Röhren und Übertrager. Der Wirkungsgrad dieser Verstärker liegt bei über 90%. Da der Lowther 98 dB Wirkungsgrad hat,..geht das ab wie Schmitts Katze schon bei kleinstem Dreh am Pegelsteller. Ich kann deine Hörerfahrung somit nur bestätigen,…Abacus und Breitbänder ist eine gute Kombination,,.High End für relativ kleines Geld.
unfortunately all actual available Fostex FE 20X XX drivers (206NV or 208NS/EΣ) have no way such nice flat frequency curves like those we saw on Your iPad, it seems the development is targeting in a new direction. (The actual EN 208 Σ has no whizzer cone as well)
Very acute observation! That's why I stalled to replace the FE204 with a newer Fostex... I think they focus on higher excursion and higher power handling. (Another casualty of loudness wars.) Then I got the opportunity to try the Fc8. It's not as dynamic/efficient as the FE204 was, but much easier to match to room and very easy to get powerful and deep bass which the FE204 just flat out refused to do when it did not like the room or system. Although very expensive driver, but it delivers every penny of the asking price. (Please note though that I received it from CA as a gift, so that technically can be a bias.... yet, they did not ask me to review it, nor to talk about it, so I'm doing it because I found that it delivers, simply, by far the best FR I ever came across.)
Keeping scales the same, it is by a very long shot far flatter than any single drivers plot I have seen. What it can do, is simply astonishing (I was). Not just from a single driver, by any loudspeaker technology. What it can do with a 1 cuft cabinet should be impossible, yet it isn't. I have not heard 2-3-4-5 way systems with far larger cabinets, at x20-50 the price have a natural realistic sound like it; (of course I heard some that do, but the vast majority of that performance range not even close.)
@@realworldaudio I'm a fan of fullrange/ wideband / single driver speakers and have a few. Something I also like to highlight is that a fullrange speaker probably makes for the best midrange driver in a multi driver setup where they can operate in a smaller spectrum of their capabilities, far from breakups and just in their midrange lovely region where they tend to shine the most.

Sold those speaker to a friend.................indeed very fine sounding units !!!!!!!!!!!!!
Once again... KILLER thumbnail👏😈
I generated the female figure with AI (Nightcafe), and then Photoshopped it with a Fostex driver :)

Hi Roland, sadly, never heard of the brand... none made it over the two oceans to Hawaii : (

@@R0W57 Abacus ist echt toll, bei Saba wurde mal eine ähnliche Schaltung verwendet.

@@realworldaudio Thanks for Your estimation, they are offered in Austria/Germany as well, so I will consider them later!
The diatone frequency plot is far from detaild. Its 10dB between the lines. With that said, its probably a awesome driver!
