I just got finished, like 30 minutes ago, stuffing my 12 ready bags.
I can't believe the difference the bags make! I put them all over my room and just started to listen to a couple of songs, and man the sound just opened up on my new hs50m's that I just got. FedEx dropped off my yammy's before I went into work last night and I was not overly impressed by them. After I put all my traps in the room, the difference is really night and day! The bags, which are black btw, look great! Except for some mineral wool that found there way to the outer surface of the bags, but I will clean them up later today. I'm very happy with my bags so far and can't wait to play around with some placement to get my room as perfect as I can get it.
