Ok, so the wife has decided to live with the old speakers a little longer before looking to replace them So we still have the Denon AVR-2310 with Mission M74i. M7c2, M7ds and M5as attached exactly as they were in the old room. The new room however is much smaller, probably half the size, though in the old room there was a large space behind the main listening seat in the new place there is a moderate space to one side and almost none behind. In the old room normal listening volume tended to be at about "-50" on the amp for normal TV and "-35" for DVD/ BluRay. Using the same kit/ sources etc I am now finding "-30" is needed for TV and "-20" for movies. Whilst I dont play anything VERY loud just to interest I pushed the amp to maximum and it was much quieter than it used to be. The auto room EQ was run in both and whilst distances etc are all different etc the ± on each speaker is almost the same as it used to be with an average of probably +0.5. Any suggestions whats going on? I would have thought the same speakers in a much smaller room would have sounded louder rather than quieter, especially with the loss of a "void" to fill.
