I have two APM speakers wired up to one connection and they sound great together.

I’m glad you’re getting a chance to enjoy them. Not enough people seem to. Thanks for watching and commenting!

I have a pair of APM-20ESs, they actually sound pretty awesome if they are connected to the right amp. I am using a late 80s Technics new class A midi system and the addition of super bass really makes these small speakers come alive. They have the 4 coil design as the woofers have four dust covers in a square pattern on the woofer. I believe some of the larger ones had five. I've also got a couple of Aiwa systems with flat diaphragm woofers and AFBS (Acoustic Feedback System), which actually mikes up the speakers to ensure what's coming out of them is the same as what is going in. I found the description of the "advantages" of FD speakers interesting, as I have noticed the sound is excellent when equidistant, but quickly loses bass if you move from the centre position or are elsewhere in the room. Perhaps there are advantages to _not_ having all the sound reach your ears at once, although I am comparing against newer, floorstanding models that are no doubt superior.

Thanks for sharing your experiences as we all have so much to learn from each other. I'd love to find a pair of ES's sometime. Thanks for watching and commenting!

@@new2uspeakers I found an article on the 66ES speakers that shows the back of the woofers, turns out they use a single coil with the diaphragm supported by several posts. I won't link as YT will probably delete the comment, but if you search "amazing sony apm-66es" the first results should be the Sound Oddity blog. 😀

Sony in driver tech & bose in Enclosure tech are the legends of audio industry which don't get the reputation they deserve.

I also see three things in common with both companies. 1) Technology and innovation, 2) outstanding marketing. And I think those to lead to 3) Longevity. There are probably some lessons to learn in that. Thanks for watching and commenting.

If only Bose only had even halfway decent drivers, a real tweeter, and a crossover they'd be pretty decent. As they are, they're utterly crap-tastic. Same with Sony's enclosures and crossovers - cheeeep n crappy.....

There is a small Japanese-based company that carried on the APM speaker design but really elevated them.

Crazy, I’ve got a set of fostex drivers with dual coils/mags per cone, oval shaped but the ES reminds me of these, can’t find anything on them.

Since Fostex is still in the business , they may be the best source of info. It can't hurt to reach out to them. Many Japanese companies love their history and may have some support. Thanks for watching and commenting.

Compared to what Sony invested in the mid range and woofer, there’s certainly nothing special in the tweeter to put them at the top of any listening test. But they are interesting. Thanks for watching and commenting!

I really didn’t hear significant problems with the drivers, although the tweeter is nothing special. If they don’t sell soon, I was thinking of actually repurposing the drivers into a newly constructed box. I think that could improve them a lot. Thanks for watching and commenting!

🟥Those are not planar magnetic drivers.🧐 I've heard these speakers, not that good sounding.

@new2uspeakers

You are absolutely correct, they are not "planar magnetic drivers" as can be found in many headphones and some other driver manufacturers. I rechecked the video, and I'm pretty sure I didn't state that, as I would not not want to confuse anyone. Hopefully you learned a bit about the Sony technology of the planar honeycomb using a traditional voice coil as described in the patent. Planar magnetic driver technology is a good idea for another video, and thanks for watching and commenting!!!!
