What is the best full range Speaker ?

Vmps will always be considered full ramge, will work good in your room I bet and will look cool in there for sure.

Of the many speakers that might work for you, the fairly efficient Devore Fidelity Gibbon Nine's might be worth your time to audition. They are impressively dynamic for their size, are quite detailed, image well, and have excellent bass and upper ends with a superb midrange. And they are in your stated price range.

Just thinking aloud here....

If you liked the Focus, then why not try for the Legacy Whispers? Especially if you are putting them on the long wall. In spite of their eff rating, it is my understanding they work better with decent power supplies & good amps.... 200+ wpc.

Finding a pair of them for 6500 should allow you to corral a good high powered amp, like a MC602 keeping you close to your budget of $10K... but that's buying them preowned.
