They won't cancel each other out when they are not wired in reverse of each other. They are 2 DD with diaphragms facing each other. I think @piotrus-g can give us a bit of hint with this config. They did something similar which is really really interesting.

Hehe I can't comment much between NDA and MOT rules. But yeah I've done exact same DD alignment. You want both DD in the same electrical phase and they won't cancel each others frequency - think of this as DD equivalent of dual BA driver.

When I saw the design, I remembered your collab instantly. Thanks for replying, tho and not leaving us hanging. Your presence and contribution here is very much appreciated.

Hey all, I'm sure some of you have seen the new Blessing 3 dual DD configuration. Has anyone tried this? Could two normal DDs be used like this? Cheers

EDIT: Sorry, I was not reading properly. I think the coil is in the middle of the two DDs, so it is one DD coil pulling both diaphragms towards it. However, what would happen if you did put two normal DDs firing at each other? Would most of the sound be cancelled out, but with the change in air pressure being blown into your ear?

This works and it sounds very good. I personally always use this design in my configs, you should try it too!

I also use this type of 2x6mm config in push-push mode and also 2x10mm.

we find this type of mounting also on the AAW canare or the Camelot but no idea if they mount them in push-pull or push-push

I always thought the canary is a push-pull since it's called isobaric.

They talk about push pull it seems to me, but having done tests, the push-push sounds better to my taste

Does 2 12mm DD sound overkill even if I wanted FATfreq Maestro SE levels of bass?

Size sometimes means nothing

They guys which AGAR you use? Or where you buy it ? I want to try it cuz
I use gelatin and glecerin mix.

Soundlink has them. Try inquiring about their stuff.

Is there any other option? Like to buy in US? Cuz Their shipping cost a lot

I have a diy recipe posted in here somewhere…. Its what I still use.

But it is a gelatine mix you use right? That what i use too , just wanted to try the agar agar

Very interesting, thanks for all the replies guys. I might knock up a simple enclosure that looks like that and see how it measures. If there's no magic going on then it definitely sounds like it is worth a try. Cheers
