Best monitor for bookcase ?

Add KRK Systems to your list,they have active and passive and sound very good...Bob

Allison Four or Allison CD-6. If you find a pair of either of these classic systems...grab 'em! Nothing else can beat 'em at any price!

Better 7 1/2 years late than never :)

Polk Audio LSIM 703 monitors are AMAZING !! I listened to a pair of these today and I was just blown away with any kind of music that was playing and I was shocked when I seen that they had these speakers hooked up to a cheap av Receiver and a cheap blu-ray player !....

To my ears, these speakers are one of the biggest bargains in all of audio... of all time !!...

Sonus Faber Toy Speaker (monitors) - they deserve to be on the audition list. They are small, inexpensive, and beautiful sounding. I am listening to a pair right now and they do a great job of pulling me away from typing to listening. They are in a small room (about 8.5' x 10.5') which helps. The speakers are rear ported and proximity to the rear wall helps in their case.

They are driven by a 30wpc tube amp, fyi.
