Is this a new trend?

yogiboy, Acoustic suspension was instrumental in the early design of small speakers but it is essentially dead these days. Thiel/Small research into the design of bass reflex speakers allowed the design of small ported speakers which are more efficient and bassier although usually with less bass definition. Today the concept is misunderstood and almost everyone including reviewers call any closed box acoustic suspension when it almost never is. Acoustic suspension is a special variant of closed box and all closed boxes are not acoustic suspension. In fact the drivers today have design characteristics for bass reflex and can't work properly in acoustic suspension boxes. Edgar Vilchur must be rolling in his grave after his concept once had 2/3 of the audio market before Thiel/Small.

@viridian has a point. The number of houses I've been in even in my own Gen X that still have floor standing speakers is pretty minimal. Anybody who has anything up from a sound bar usually has a pair of bookshelf speakers. Maybe a sub if they're feeling really frisky. And Millennials and gen Z? Do you think they want to deal with floor standing speakers, especially those who stream most of their stuff?

Most reviewers  have small rooms hence they test small speakers. 

Some of them are bluetooth.kids don't like wires.small house if they can afford it.glad is lived in the era i did.other than covid it was great.best audio ever stream, lp, cd ,tape and you can have it all.enjoy it while you can.
