I couldn't disagree more. I have a reasonably large masonry fireplace in between 2 main speakers, and the fireplace plus chimney gives a hollow boomy signature to the sound. The only solution was to wall the whole affair off with tube traps, thanks to which the speakers now have normal staging and a reasonably linear frequency balance. And that is with the speakers well out (55") from the front wall and fireplace.
Sub In The Fireplace
Was wondering what your thoughts are on this. I currently have a Velodyne HGS 18 II, which I have tucked in my fireplace... The mains sit on either side, with their plane about 2 feet closer to the listener. The fireplace, which I obviously don't use, is pretty much in the middle of the wall. The sub fits easily with approximately 2 - 6 inches of breathing room on any given side. Being in a fireplace, the sub is surrounded by brick on 5 of its 6 sides. The house is on a slab. Is this a good thing? Am I losing anything having it there? Advantages, disadvantages? Should I consider insulating the breathing room the sub has all around it?
