Hello,
Typically an amp will increase wattage when driving lower ohm loads. A 100w amp might go to 160w at half the ohms. It doesn’t always double, but it usually increases. I don’t think power is an issue unless you hear clipping at higher levels. The rock wool could be a little too much if It is really thick. You are drowning out the mids and highs. And the drapery could be too little. Especially if it is not symmetrical. Room treatment is an art. You could be absorbing too much of the highs and those treatments you talked about do very little for bass. Plus the left side should match the right. You might want to switch or add defusers so you don’t kill your highs. At low levels your 7” drivers are balanced or barely keeping up. When you turn up the volume they could be drowning out your mids and highs. I think you need to test with near field listening. If your speaker wires are short get some cheep longer higher gauge wire and put those speakers in a 6’ - 7’ triangle to you. Remove some of the sound of the room. If it sounds really good it’s not your amp or the speakers. It’s the room. Redo the room treatment. Last but not least. Get two subs. My speakers are rated to 25hz. I still have two REL 9t subs. MC has four in his room and he has monster Tekton Moabs. Subs balance out a system and make it seam like your system is a 1000 times bigger even at the lowest volumes. Like I said your 7” drivers might not be moving much at low volumes but a sub can. When you rock out the sub can take over every thing below 50-80 hz. To do: Near field listening to determine is your equipment matched, balance absorption by removing or less thick rock wool to balance curtains, diffusers instead of absorption in some areas. (GIK.com), last but definitely not least a sub or two (sealed and 10” driver/s) stay away from ported subs- too sloppy in most cases.
