speakers for classical music

What are good models and manufacturer's for actives?

Genelec 8050A - you may find these at your local music or guitar shop - they will probably be close to the best of the active near fields mini-monitors you can audition at a pro music store (where they sell musical instruments an studio gear)- try to listen and see if you like them - I think they are better than Mackie's - if you do then there are a few others I would add which are difficult to find for an audition and even more expensive and will essentially play louder for far-field listening - so it is probably best if you check these Genelec's out first and see if it up your street. (You may not like the neutral sound -many don't)

What are the downside to actives and why do are there so few active's as opposed to passives?

This has been discussed on other threads but basically you are limited for "tweaking" through choice of your own amp - especially important to tube lovers - as you won't find a tube in an active speaker (due to microphonics of tubes)

Most any maggie, assuming you have the room to let them breathe, but that is true for any speaker. You need a good size room and room around the speakers to develop a proper sound stage. Add to them powered sub. Better still biamp and add a Behringer CX3410 crossover. Now you will hear classical as it should

My ultimate reference for what a system should sound like is live performances.

When I owned Maggies ($900/pair new in 1986) and was able to have them set up properly, they never disapointed with classical music. What I heard was a most accurate reproduction of what I heard when attending a live symphony.

The only other speakers I've owned that I can say that about are my current Ohms.

My ultimate reference for what speakers should sound like is what live performances should sound like. . . in theory. Unfortunately live performances I have attended never sound like what they should. But then, my experience is limited by the Teatro Alla Scala, the Sala Giuseppe Verdi at the Conservatorio DI Milano, The Royal Albert Hall, The Basilica Di San marco in Venice, Notre Dames in Paris, and the Tomsom Hall in Toronto. . . although I do admit that the 16th century portcature in Groznjan (Istra) near Trieste comes very close to sounding right.
So in the end. . . I just follow my ears and hope for the best.

I disagree with those who have said Quads ESL 57 are the perfect choice for classical music. I own a pair of them, I just love them, but I think their limit is that they can't play symphonic music right (meaning, reproducing as closely as possible live performance). I am not talking about chamber music...they are just sublime there. I am talking about symphonic pieces that require a fair amount of air to be moved. That's what you feel in real life concerts, at least in my experience, and this is Quads' main limitation, again, in my experience. Too bad: apart from this, they are just perfect speakers. My two cents.
