Warm and accurate bookshelves that can handle volume

Diapason adamantes or music culture rl-21. 
both very difficult to find on the used market. 
some of the best 2 way monitors for the price you can buy. 

Thanks much for all this great advice. Just want to answer a few of the questions:

1) the room is 15 x 20, but the speakers are about 6 feet from the back wall. On one side wall behind one of the speakers there is a 6 foot opening to the rest of the house.

2) I misused the word accurate I guess. I meant that they were able to reproduce the timbres of instruments. I can really hear the difference between oboes, clarinets etc. Massed strings are not just one mess. (I like rock and roll and jazz, but really hearing the nuances of classical music is the ultimate for me.) 

3) Re the subs, I have heard that it is best to use a crossover on the sub itself and let full spectrum go to the satellites. Others have said you can help your satelittes by shunting all the low frequency to the sub. I use a second preamp out to go to the sub amp, and there set a low pass at about 50 Hz. The speakers have good output until about 50. 

4) I go for about 80 or 85 as loud

Thanks again! Enjoy the music.

Human Speakers model 81-DK... 

Or, the venerable Epi 100 w new crossover-capacitor from Human ... it's a "timeless classic" for a reason.  

If you really want output you need surface area to push the air - a single larger driver and a horn loaded compression tweeter. In other words, a JBL Pro-style studio monitor. A model 4349, with a 12" woofer and 1.5" compression horn tweeter with a large format horn. As JBL says, "This combination delivers music with authority and accuracy not possible with traditional loudspeaker designs." For comparison, an 8" woofer has an area of about 50 in2, and a 12" 113 in2. The smaller driver simply has to work a lot harder - and requires more power - for a given output. There's lots of other variables, of course, the basic physics remain. Big output requires big speakers, big power, or both.

Lintons, LOL Love mine. You had me a warm and accurate.
