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

For me, some of the most underrated, or least heard and appreciated, are the old Apogees - particularly the Duetta Signatures and the somewhat smaller Stages. Both the Duetta Sigs in a medium to large room and the Stages in a small to medium room (when driven with adequate power and set up properly) present the accuracy of timber, the detail, stage and intimacy of the Quads with the fullness, harmonics, ambiance and dynamics of a live performance.
Very close would be the Sound Labs Electrostatics - 545s, 645s or 845s, depending on the room to fill and your budget and of course, the Magnapans.

For me the most overrated would be most $25K box speakers that have all the dynamics of a live performance but detailed to the point of being etched and lacking in the air, ambiance and timber of a live acoustic performance...Jim

And just because a speaker is 20-30k... doesn't mean its good.

I'll take the top end Salk's (9.5, SS10, SS12) all day long over the Wilson Yvette, any Paradigm Persona and a few others all day long.

To me, the Wilson Yvette is merely "ok" and way overpriced.  Now the Sasha 2, with the soft dome tweeter, used at 20k... that's a damn fine speaker.  At 36k... ah that's overpriced.

We get you think Salks are "merely" ok... but it's really really hard to find a thread on any page, or a review by anyone that doesn't think the world of what they get for the money, which to me accounts for an "underrated" classification by many.

At 20k plus... I would EXPECT a speaker to be phenomenal (though many are not).  Heck, the Persona's to many fall in that category.

Now in the stuff you endlessly push out here, I think the Legacy Focus SE is a heck of a speaker, and for what they can be found for used can be a great bargain.

I think the ATC stuff sounds damn good, but it's just so freaking expensive for what you get.  The 50's (both active and passive, but particularly Active) are pretty amazing. 

Fun topic, but meaningless.  Sure, I have my entries in both categories (overrated KEF ls/50, underrated Vandersteen 3A  Signature), but like all else in audio (and the world) it's a matter of personal taste.  Vandersteen is never going to sound great to millercarbon, while they do sound great to me.  Both valid views.  Maybe the real takeaway from this discussion is the highly variable reliability of professional reviews.

Another example:  Wilsons don't make music for me, but apparently very many people love them.  I'm not about to dispute their taste, and in fact am glad they enjoy them.

As I am reading this I am enjoying my overrated B&W 802d playing an excellent Led Zep II on my vinyl rig.   I have no plans to ever change them.  Why?   I love the sound, already have them and they are too damn heavy to change out easily.    Of course I am curious to hear other speakers  with my setup but I love the music and enjoy them every time I listen.     Jumping around seeking “better” isn’t always so satisfying.
