Looking for new speakers for large audio room

I have a pair of customized Tekton Double Impacts with ribbon tweeters in a large room and couldn't be happier. Tremendous bang for the buck. 

Are you replacing the Avantgarde uno series two? Thought you were just looking to upgrade. Those are some great speakers. Can you afford some Avantgarde's with bigger horns and 4 subwoofers?

Audio satisficer I did not know Tekton double has ribbon tweeters? 

The Persona 9h would do the job. I had the 7f and was floored by the bass passive speakers could put out, sure the mid and tweeter need to be matched to component en to by ear, but when they are oh baby!
A used pair of meridian dsp 8000’s will cure any bass problems and if you can get a special edition pair they really are very good. 

Seems like your amp is really the limiting factor.
