Songer showcased another full size field coil speaker, these sounded to me more refined and engaging than the Jones & Cerreta, but is the system as a whole I was comparing, obviously.
Yes, Songer Audio S1x. I took the flyer below. I loved them too, one of my favorites of the show. That system did everything, full bodied sound with a lot of presence, the veracity factor very high. Might expensive at $45k though.
An educated guess tells me much of that comes from being a full range crossoverless design more than anything else. It’s basically all the benefits of an active crossover and more. Allows for direct coupling of the driver to the amplifier (like with an active crossover) but a simpler signal path because there is not even a crossover further up the chain.
I say this from experience with other full range zero crossover speakers. Somehow the “presence and voracity” (I tend to call it immediacy) lives outside of the factors of detail and clarity.
I wasn’t suggesting it was. Merely pointing out that from long experience with active and crossoverless systems, those qualities of veracity and immediacy are separate from detail and clarity. You can get those qualities on less clear/detailed systems and a much lower cost of the spectrum. I don’t believe it to be related to the driver tech or overall speaker cost so much as the amp coupling.
You can experience this with older Linn and Naim active systems where an active pair of SBLs driven by a pair of NAP180s had more presence and immediacy than passive DBLs driven by 135s despite being less clear and detailed. Ditto entry level Linn speakers active versus high end Linn passive.
Obviously going for clarity, details and presence and immediacy is preferable but one was not a direct consequence of the other. This was the whole reason a person might go active with something like Intros instead of opting to simply upgrade to SBLs - do you want more clarity and detail first or more presence and immediacy first?
I say this as a huge fan of going crossoverless and single point source.
Indeed - it is nothing to do with how the magnetic field is generated per se, as an identical driver having a magnetic gap of the same dimensions and same distributed flux density using permanent magnets would sound the same, and likely no less easy to make (maybe easier).
There is no way after reading that I would be able to resist doing everything it said not to do I’d start with a length or rebar waved in front of the driver. I just wouldn’t be able to stop myself.
The irony of Japanese high end speakers is that they design absolutely gigantic speakers, and have no place to put them other than two feet apart with the listener practically on top of them.
