Name 3 classic mini-monitors worth keeping- Why?

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'll second the Proac Tablette 50 sig's. Love mine!

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.
