Yes, this was a truly extraordinary system, end to end. Come see us at one of the shows, we'd love to host you for a listen!

@@songeraudio24 I will definitely try to get to one!

Cheers, they certainly did... top marks from Jason and his group two years in a row at this event, pairing with different systems no less. Amazing. Our next show is in Seattle in September, we'd love to see you there!

Sure, Dale. The power supply is variable between 9 - 12.5 VDC. The design is proprietary courtesy of Whammerdyne Heavy Industries, and you can read a little more about it here: songeraudio.com/products#ps1 The power supply doesn't produce much heat, and what is does is well-managed by syncing to the aluminum case. The field coil motor never becomes more than a little warm to the touch in the open baffle S2. In the S1, it's a good practice to just turn off the power supplies overnight and at at the end of listening sessions.

Feel free to call or email us, Keith. I'm sure we can find a way for you to listen.

The spider is actually quite linear. I can't comment on electron charge versus electron spin. While I have read that as well, I agree it may be irrelevant to the performance of the driver. The difference with a field coil is simply attributable to the permeability of the magnetic material, not anything new to magnetism. The higher that figure is, the stiffer the magnetic field, and in carbon steel or permendur that number is very high. Even when a magnet is very strong, as is the case with neodymium, the permeability is similar to ordinary ferrite and the accuracy of voice coil modulation suffers as a result.

@@songeraudio24 A fact that you as a designer can select a field strength, could help to get better numbers. With no doubts. I will monitor a situation with FC drivers. It would be great to find this market growing.

@@sc0or Cheers, and thanks so much for your comments. They are always most welcome, and appreciated.

Thank you, Everard! The DAC is spectacular, and also outside of my budget; but if you can afford it I highly recommend it. I have a Mola Mola Tambaqui. It may not quite share the rare air the Poseidon occupies, however it is also staggeringly good.

Stephen, I regret I didn't see this comment much sooner. Hopefully this objective review of the S2 from Marc Phillips, Editor-in-Chief at Part-Time Audiophile will paint a picture of the dispersion characteristics: parttimeaudiophile.com/2024/03/08/songer-audio-s2-loudspeakers-review/

I know, right? Come see us at THE Show in June... ;)

Thank you for the kind comments, @Full Ranger! Even though electromagnetism may offer the greatest potential, it's only part of the story - lots of great loudspeakers in the world, and only a handful are field coils. Many use neodymium! In our driver, the materials, the soft suspension, the lightweight moving mass... each plays a part, as well. Cheers.

Not yet, Anne - we're focused on the S1 and S2 for now. We likely will in the future, however - another year or two is a good bet.

@@songeraudio24 well I start saving my nickels then 😁 would be lovely if someone did a comparison of your driver and something like a voxativ on an ob application. Any audio CZcamsrs lined up to do content on s2?

Cheers @@annebokma4637. On CZcams, The Audiophile Junkie has covered us a couple of times at the shows in this debut year and said some really wonderful things, especially in his CAF wrap up content. I think I may be the only person who has auditioned both a Voxativ and our driver in an open baffle... :) Here was the Audiophile Junkie's visit to the CAF room: czcams.com/video/C_BsmpQinEk/video.html

@@songeraudio24 very nice content indeed. Thnx for pointing me to that. Would love to hear what people like Steve and Thomas think of the s2. I am already very impressed with the look of the driver, how it sounds from this distance over CZcams remains an indication. Maybe an European show in the future? 😁

In our current design, there are a little under 1600 turns.

I hope you'll have a chance to hear them, one day! We'll be at T.H.E. Show in Costa Mesa in June, and at the 2023 Capital Audiofest in November this year. Cheers.

@@songeraudio24 will you be at Pacific Audio Fest?

@@cliffordthompson5778 We're still thinking about it! There are only two weeks between THE Show and Pacific, so... it'd be an awfully tight turn for us. I'll try to circle back and let you know in a couple of months though, as the picture gets clearer.

Thank you, Bolse!

Thank you Bruce! I'll be documenting a client build of a pair of S2s on whatsbestforum.com soon, please do feel free to read along when I begin the thread, it should be fun to share.

Hi Everard! A magnetic field may be very strong, but not stiff as it responds - neodymium is a good example of that. Another good analogy to illustrate the concept is a car jack. A strong jack can lift a lot of weight (tesla), but if it's sitting in mud, it sinks and slips as it lifts the car. The stiffness is the surface the jack is resting on. If it's sitting on concrete (high permeability), it will remain precisely where it is as it raises and lowers the car.

@@songeraudio24 Thanks Ken for the additional clarity. So it is not just about higher the tesla number. That stiffness is also a consideration. What is the unit measure and I wish that manufactures would report off of the data.

@@songeraudio24 could this also be described as a type of temporary “decay” in the field strength under a specific “load” IE the movement of the coil due to the signal?

@@polkiju7 I don't think it could be described as a decay in the field, per se. Permeability is conventionally a property associated with the material of a permanent magnet, and it indicates the degree to which the electrons in that material are spinning in uniform alignment with one another, at least as I understand it. An electromagnet can at it's limit achieve saturation of the material, which in low carbon steel, pure iron, permendur, etc constitutes a very high number. What you're describing is a bit like parasitic inductance. But bear in mind, a degree in physics is NOT among my qualifications. :) My education is ongoing... a big part of what I love about this work.

Thanks for the elaboration. Certainly more complex than I imagined… like so many things!

Thank you Carl!

Cheers, I'll be looking forward to making a pair of them for you!

How much are these How low do the go

​@@cesargutierrez4999 The S1 is $37,000 with power supplies, and are available in a wide variety of wood species and finishes. You can expect excellent response to at least 30Hz. In a typical space however, bass performance rolls off to -6dB in the mid-20's.

Cheers, Alan!
