Looking for a good full range floor stander

You have the power and room size for 10.7 Maggies.  Elizabeth often posts about hers.

I almost bought a pair when I bought my 3.6s, but my room was too small.

Just food for thought.

Von Schweitzer’s  mk3 arec very nice 

You didn’t say anything about budget, so I’ll throw a couple out there that could handle your room size. Legacy, Focal Utopia, Magico come to mind. 

Tekton Pendragons or Direct Impacts. 
I can highly recommend both speakers. 
You also save a good amount of money because you buy directly from Tekton / Eric Alexander, who is the owner, engineer, and designer of the Tekton line of speakers. 

I went to last year’s RMAF.  I visited Jim Salk at Salk Audio.  I listened to his Song3 Encore towers priced at $6,00/pair and they sounded better than a pair of $60,000 speakers down the hall.  Can’ imagine what his more expensive speakers sound like.

Jim sells direct.  He told me he was not willing to use inferior drivers and cabinet design in order to sell his speakers at a discount so dealers can make all the money.  As a result, he uses the most expensive high quality drivers.  I promise you, they are the best speakers you will ever hear.

i am sure the dealers who participate in this forum are rolling their eyes.  And no!  I am not working for Salk Audio.

Call Jim Salk and tell him Larry Edwards sent you.  You are in for a treat.
