Hi Luna,
The batts inside the walls are good. The muddiness in the mid-bass can be cleared up with a product like ASC tube traps (I am a dealer) or other brand bass traps.
Jim Smith's book is a good read, even for knowledgable audiophiles.
Liveliness in the room can be a number of things. First thing I would assess is are there any very absorptive materials in the room that may be contributing to lack of livliness?
good luck, hope that helps
