What are some of the most underrated and overrated loudspeakers you’ve auditioned?

For me personally the most underrated speaker would be the Alon II. It's an ugly duckling, needs plenty of space. But the sound coming out of that speaker is really special!  Soaring highs, boogie factor and good bass. Also the prices they go for.... If people only knew. It stomps on a lot of competition. 

Overrated is difficult. I would say Sonos. Yeah I know. Also those Jbl 's mono things. They can go loud sure....... B&W 800d3 didn't do it for me either

#Offtopic: Tidal! Just compare Tidal VS Quobuz in sound quality. I was shocked and canceled my Tidal subscription instantly 

Paradigm Atom v3- I bought a used pair for $20.00 recently and they sound fantastic in my small bedroom. I can't imagine a $200.00 pair of small bookshelves sounding better, even today.

I didn't care for Klipsch Heresy of unknown vintage I bought used off Craigslist. These were easily the worst pair of hi-fi speakers I ever owned.

The Audio Note AX-Two was a good used speaker for the $300.00 ($549.00 new) I paid in 2007. They now have more than doubled in price at $1200~. I think these are overrated based on all the hype I read about them on AudioAsylum back in the mid 2000's and my ownership experience.

I wanted to add I agree most psb speakers I’ve heard have been pretty good. The Stratus Mini has been my favorite small speaker for awhile now.

It seems like alot of the speaker companies I’ve heard can’t get basic musicality right, which psb does (and the Paradigm Atom v3) so easily. Many companies go for a "analytical" and accurate sound at the expense of being unmusical and uninvolving. With these type of non musicalspeakers I never forget I'm listening to a pair of speakers.
