What is the best full range Speaker ?

Vandersteen 5 and Quicksilver V4 Monos
The most important thing to have with full range performance is top to bottom coherence.
The room compensation feature in the Quatros and Five series makes this a reality.

Your room is not that big so you should find many practical high end choices that you might afford depending on your taste and preference.

From my discussion with Bill Dudleston, the specs of the Focus HD are 20Hz - 22kHz +/-2dB. I reviewed the Focus HD for Dagogo.com

my recomendation would be the jbl 4430 or jbl 4435 studio monitors...very dynamic. coherent, excellent power response, low distoration, great base, great efficiency (not sensitivity)excellent imaging and they can take all the power you can give them...an all around great full range speakers. driver quality is second to none. but like any other great speaker correct set up is important. and on the used market you wont have to spend $7k...and by chance you dont like them you can get your money back as they hold their value quite well. best of luck!

John if you can find him a 5A for $5-7k then let me know and I will buy them first!
