@OP. You need to measure the room. An excessively absorptive room can result in some fairly serious frequency response anomalies. Its more likely to cause suckouts - but the absence of one frequency can seem like an excess of another. A set of test tones and an SPL meter will tell you a lot.
Room Too Dead
Hello All,
I am looking for advice and ideas on how to condition my Home Theater room. I built the theater in my unfinished basement. The foundation walls are covered in insulation and vapor barrier. Instead of construction walls to cover them, I chose a "pipe and drape" to cover the walls. I believe that the room is too dead. It seems to affect overall soundstage in the midrange range. Does anybody have experience with this problem and ideas to add a little "excitement" to the room? Thank you all.
