Classic speakers to hunt down used

I am too inexperienced on hifi to know what my style is - yet. I teach classical music, so I like speakers that are little dark sounding - not too forward. I like old Jensen and Tannoy coauxial 15 incher (too expensive though).

So please recommend any good sounding classics I can get for a few hundred $ on ebay.

I am now listening to an old Jensen alnico magnets, with an old Marantz receiver - and it does it for me. I can't think of modern gears giving me this much joy for this little money - although I don't know too many modern ones to be honest.

I heard so far:

Parasound
Nad
Krell
Arcam

I liked them all.

I am not familiar with Chinese Hifi - but heard good things about them lately - like Cayin tube amps. If someone knows of them, please enlighten me.

Basically, I am interested in any good sounding gears that are good value - I have to put together systems for 1 to 2 thousand $ and offer them to my music students for their education.

They need to hear quality to improve their ear, and refine taste. It's hard to find systems for that little money to do all that - but most parents can't see themselves spending more for hifi (sadly).

Thanks again for all the suggestions - I will hunt them down - my students thanks you all.

I owned, listened to and sold many of those speakers in the early 70's. The AR-KLH-Advent followed a certain lineage of Henry Kloss and the Advents easily outplayed most of the comparable box speakers in the day. The big AR3a was probably a better speaker, certainly better built, as was the KLH 5, but the Advent had a less wooly sound, at least when driven with the mediocre solid state receivers that were usually coupled with them.
AR made a 'big' speaker, called an LST, which Levinson later used in multiple sets- don't know what mods he performed on them. Those would be pretty rare, i think, and probably insanely power hungry. Most of those 'acoustic suspension' speakers were very inefficient, and were mated with solid state equipment which offered higher power and 'lower' measurable distortion.
I am not as familiar with the small Infinities of that day- their claim to fame was the multi-piece Servo-Statik, and later tower speakers with monster woofer arrays.
EV- other than horn speakers, I don't remember much in the way of bookshelf speakers in that era, except for one that was equalized, and actually sounded pretty good at the time. The name escapes me right now.
Best bet, imo, is a refreshed pair of Quad electrostats (aka- 57's) with a low powered tube amp. I switched to this kind of set up in about 1973 and never looked back. (Except recently, when I bought my first large horn set up, go figure). Good luck.

Another classic of yesteryear you may consider is DCM Time Windows.

What is the budget? My wife is a classical musician played professionaly , a violinist. She was quite taken with the corect timbre of a Consonance tube amp we ran across. And I personally like the VR1 bookshelf but its probbly too bright for you my wife insisted on the VR2s which are floor standers. If you have a small room the Omega sngle drivers and thier other speakers are magical with a small tube amp by SQ which is a brand distributed by Stephan Monte if you live near Philly audition them. Otherwise call Quest for Sound an A'gon dealer he will set you up with what you need. He carries inexpensive stuff as well as real High End but don't worry he is a super nice guy not snobby all what you can afford he'll have.

If you have SET's. the EV12trxb will be incredible...Lively, dynamic, with a midrange to die for...and not very expensive. I also have some Tannoy Monitor Gold 12's and they sound great with anything driving them, but are many more $$$$.

The best buy I made in bang-buck ratio is the ADS L-700 and Braun L-810. One of the best tweeters around bar none. They also sound great no matter what I drive them with.
