Hello I am rather new to this forum and would like to ask some questions regarding my new sub that I have just purchased. I purchased a Velodyne CHT series 8 sub last week and have hooked it up to my system that consists of Pioneer VSX D 850 reciever and drivers are Jamo 265 front standing and jamo center and rears. I have the speakers set to small amd have the crossovers set to around 80 hz. At the moment have not calibrated by meter as i do not have one and live 780kms from the city. My problem is that the sub works fine when I increase the volume of the amp,if I leave it in normal postion it is hardly noticeable, question is this normal with velyodyne series or is ut just that the floorstanding Jamo's push a fair amount of bass on their own. Also what would be a good dvd to play to see how the CHT 8 really perform.
