Just got a Loewe Mimo 28 with DD upgrade and Tremo speakers. My problem is this... When I go to set up the speakers via the TV I get the option to set up Concerto speakers or BOSE but not Tremo. If I use these then the volume is very loud and uncontrollable - the neighbours won't be too happy. I can use the 6 channel setup but its obviously not Dolby. What can I do to fix this?
