Given the size dimensions you specify, there aren't many speakers that are going to "blow you away". Listener magazine just ran a review on small speakers in the $500-750 range, and the speaker liked best by the 2 reviewers was a Reynaud model (see the article for specifics). I would also audition the Sequerra Pyramid MET-7, which sell for about $1000. Richard Sequerra designed this speaker, and it's a jewel. Sequerra sells the speaker direct, and has a Web site.
Best very small Speakers (at any price)?
I'm building a portable system that will fit in a small equipment suitcase. I'm using a 47 labs Gaincard (50w/ch) amp (that has stepped attenuators to eliminate the need for a preamp) and some yet to be named portable cd player. Has anyone heard some very small (maybe 9"x6"x6" or less) speakers that blow you away? thanks
