I have a KEF demo disc entitled The KEF Uni-Q Demonstration: Various Artists, which was given to me by David Brown of Technosound (now no longer trading).
There is a track on it by Eddy Louis's, (French Jazz Hammond organist), called Blues for Klook. This track will test the bass on any system, depth, slam etc. It is not easy to get hold of but is well worth it. There is a version that can be heard on YouTube if you can endure the quality and certainly does not convey the scope to the track. smile
