A while ago someone - I think it was ScottG- on the full range forum here pointed to this review of an interesting German speaker which has the mid-bass firing upwards,
FJ OM review
Now I'm familiar with the recent threads about SL's Pluto and how omni designs activate the room more, but there a couple of interesting advantages to facing up with the big driver. Firstly, elimination of early reflections, important with light cone materials, and secondly, no 'rocking' force (and here I mean motion rather than music genre). They also look very neat!
