Are the speakers bi-polar, di-polar, or have a significant backwave (ported)? If so you may have issues with that large resonating chamber called a chiminey ;<{) Consider hanging something over the fireplace if that is an issue.
speakers on fireplace hearth???
Anyone have any experience with placing speakers on bricks in front of unused fireplace? The hearth is raised about 8 inches. Should I place anything under the speakers?...use the spikes? The back of the speakers will be about 10 inches from brick. Should I hang something between the speakers and the brick? Advice or websites that address this issue would be appreciated.
