Name 3 classic mini-monitors worth keeping- Why?

Anyone can name any 3 classic moni-monitors which worth keeping? and why?

I don't know if this quite qualifies as a classic, but I will nominate the discontinued ProAc Tablette 50 Signature. I own a pair of these tiny gems, and if fed with a good upstream signal they sing loud and gloriously. For such little speakers they exude a very large soundstage and presence. If I ever do decide to upgrade, it'll be to the soon to be classis ProAc Response one SC. Oh, and yes, I think the ADS 2002s were pretty darn cool in their day. It would be neat to have a pair of those.
Paradigm Studio 20 an excellent budget speaker. Fairly hard to top in that price range
I hear (and thinking of buying) Tylo speakers are great products. I've been talking to Ty and he is a great guy to work with...honest and helpful. I hope his speakers are as good as I hear people say they are.
Alon Petites. Because they sound great!!!!
Roy Allison (forgot model name!!!!). Also sound great and were a great price.
I don't have a third, yet.
1. PSB Alpha A/V, where else can you get that much sound for so little money?

2. Rogers LS3/5A (or equivalent), lots of high quality fans for 30 years.

3. Harbeth Compact 7ES-II, not really a mini-monitor, but so good, I don't see mine ever leaving me.

Celestion SL6si. These little speakers are still sounding great after many years of enjoyment. I gave my son the choice of the Celestion's or a pair of Spica 50, he chose the SL6si because of the balanced sound. My son summed it up best, the Spica's sounded good on some music, but the Celestions sounded great no matter the type of music.
Don't forget the Spicas. Such great little speakers for the time. And Fried Beta.
I agree, the PSB Alphas are pretty amazing for such a humble speaker. An outstanding value.
I heard the ProAc Super Tablette's years ago and fell in love, so no doubt the later Tablette 50 sig's are awesome too!

Rogers LS3/5a's

Celestion  SL6

No one does it like the Brits when it comes to 2 way bookshelf speakers.  ProAc, Epos, Spendor, KEF, Mordaunt Short, Castle, Monitor Audio, Wharfedale, Mission, B&W all have a place at the table, IMHO. 
Spendor SA1 from 2009.  Fantastic tonal speaker, sealed-box (acoustic suspension) so usable in applications where the much more widely used base reflex ported speaker would be problematic (e.g., close to walls or in cabinet, among others).
Technics SB C700 monitor, Diapason Adamantes, Omega RS8, Tekton IM, Norh 9.0 marble Speakers...I own all of them, I still have them, Alnico Omega as well...
This is a very loaded question what constitutes classic? Currently in production or not?

If Classic means greater than 10 years or older:

Spica TC 50
Celestiion SL 600 and 700
Harbeths most smaller models
Proac Tablette and Response monitors
Monitor Audio Studio 10
Kef Ref 201.2 
B&W 805

Most of the above speakers are nice but not classics. To start with most above are not 'mini' monitors and to be clear I'm not denigrating any of them.

Arguably the Rogers LS35a *does* fit that description though.

Possibly also the Radio Shack Optimus ProLX5, which used the Linaeum tweeter and played *well* outside its price bracket as a result.

To be fair, it might help to know what is meant by 'classic'. Older? or something more than just old?
Celestion SL6 are really good monitors but needs power.Sensitivity is like 82db so you need at least 100watt amp to drive these.One of the few  monitors that sounds better as it ages.
I have had most of the great small monitors over the last 45 years: LS3/5a, Double LS3/5a, Braun Output-C, KEF 101, Celestion SL6, Spica, ProAc Tablette, Reference 3a mm de Capo, Silverline SR-16, and I must be forgetting one or two more. Any of these are "worth keeping" if you have them matched to appropriate amplification, but I also must point out that if you want or need a small monitor, there are a few modern alternatives that outclass every one of these in every way. Well, the current Ref 3a deCapo is in the realm.

1/ Audience ClairAudient 1+1 v3. Simply the best truly small monitor ever. No crossover, so it sounds impeccably coherent. Neutral but rich in tone; fast, transparent; expansive imaging and can output reasonable bass alone. Everything vintage will sound by comparison choked and small, however tonally neutral one might sound.

2/ If you don't have the $2800 or so for the above, the ClairAudient The One gets you the same basic attributes, with less scale and foundation, for a less than half that. And it fits in your palm.

3/ Zu Cube. A full Zu FRD with coaxial supertweeter, no crossover, stuffed in a 10.5" cube. Also intrinsically coherent. Very high resolution. These cost, depending on finish, between $1000 - $1400 pair but they demand no skimping on the amp. All the Zu essential virtues in a compact, sealed cube, with bass rolling off below 60Hz. 98db and robust, so power them with 2 watts or 200. They'll rock either way and won't break the bank.

B&W Silver Signature: Nothing like it anymore.  All that silver, with Slate Stands

Totem Mani 2: The most bass I ever heard in a small speaker

Sonus Faber Extrema: Best looking, best sounding monitor I ever had
Many have heard of the Platinum Audio Solos which most seem to agree was a fine monitor but I have the Platinum Audio Reference One's Circa. 1997-1999 which are a  more refined version of the Solos.  I'm as amazed as I am baffled with how much bass these produce for their size as well as the other typical audiophile attributes.  They do need alot of clean power to sound their best  but will play very loud all the while maintaining their coherency.    Still a little uncertain what qualifies as "mini monitor" though
I am letting all my "extra speakers " go except the Spica TC 50's. They look cool, sound great and give me lots of memories of the good old days.
