Thanks for the interest and replies.

The room is approximately 15' x 12'

Tellurium Q black cables (bananas)  swapped out occasionally with LAT International (spades). No clue on what criteria to look for to create synergy. 

Also I plan on using an existing B&W PV1D sub if needed.

I have read this in a number of different forums (Agon, AK, even the slanted HUG forum mentions degrees of sibilance). Thanks for letting me know that you have not experienced this. Do they require a large amount of power or are they easy to drive? thanks
