May well be, but the active reactive force cancelation push-push gives dramatically lower box vibrational load.
You couldtake all the same pieces and rebuild the box push-push and get even better performance.

True, but in most cases it is an “opposed” physical arrangement. Push-push on the other hand is a descriptoin that covers any arrangement of drivers where the reative force is (mostly) cancelled.
It is most often seen in sets of 2, physicaly opposed, i have seen it (Martin Logan), and done a design that uses 3, but i expect drivers tightly coupled and mounted on the faces of a regular polygon could also be done.
Even numbers are easier.

No, it does not refer to any cancellation of motion. Push-push means 2 drivers operating normal polarity with typical mounting of magnet within enclosure. Just because PPSL normally refers to opposed slot loaded woofers, does not mean it's an accurate render of the acronym.

As far as i know i was the first to start using the term push-push and i would suggest that my use of it is significant and that maybe you have mis-thot your interpretation.
Hard to make sense of that. Typical mounting? Wouldn’t that be 2 divers on the same baffle? That’s not push-push. And push-push while most commonly pairs of drivers does not need to be as illistrated above. Drivers in push-push need to be in acoustical phase and mechanically “out-of-phase”.
You can make a push-push system push pull as well, but it is harder to buildas well as reduceing second. If you takeit below the third that is not so good so i prefer to use good drivers magnet to magnet.
This is typical

Push-Push does NOT define drivers being mechanically out of phase. It defines that both drivers' positive half-cycles operate as outward from the enclosure. The reason I said it was conventional mounting as well, represented sometimes by being on same baffle, is that it would be Push-Pull if you reversed the mounting.
I repeat, Push-Push does not designate mechanical opposition without actually stating that they are opposed. This is basic english.
I can have a TMWW tower with Push-Push on the same baffle, as they operate that way.
I've even seen others say PPSL means push-pull-slot-loaded with the drivers both at cone out and typical polarity. Thing is that this is not push-pull, but push-push is the reality.
I don't think you can be that gung-ho, nor be the supposed trend-setter of the term, when the definition is not described by the nomenclature or jargon involved.
Push-Push simply means 2 drivers operating in the same phase, and cone-out. That's it.
Best regards, and in no way am I being hostile,

Define it as you will (it is completely bogus AFAIC), i will continue to use the term as i have for at least 2 decades and is the common definition on this forum. I’m pretty sure i started using the term in the mid 80s.
Here for example:
Recycle Woofer
Why give a special term to convential use. Usually, 2 x (driver X).
But i will not get into a further ******* match.
