Today, 4 strong guys have kindly come together to balance the Avalon Osiris on the Apex Spikes. Since the spikes have surprisingly long threads, the speakers had to be tilted further to the side than we had initially imagined. Accordingly, the upper parts of the Osiris had to be removed again so that they do not fall off when the speaker tilts.
2 hours later the crossover and loudspeakers are on spikes (and some Harmonix plates).
A first soundcheck confirms my fear that the speakers, which have now been lowered,
still want to be moved further than I would have liked.
If one imagines the listening distances of the individual chassis as circular orbits, one can imagine that the 15 cm lowering requires a corresponding shift that the speakers or the individual chassis comes back to the previous distance from the listening position. Accordingly, I have now moved the LS further apart. Unfortunately, pushing it back hadn't done the bass section any good. The Bass response was changed anyhow due to the lower distance of the bass drivers and the floor.
I would say, the difference of the changed speaker hight was bigger , than the effect of the Apex Spikes as such.
The Osiris speaker cabinet is that heavy, that the effect of the Apex spikes is minor. But audible...
Now I'm going to listen to some music, tomorrow is another day when I will continue to push the heavy speakers into the best position.
The intermediate result achieved is definitely quite good, so I will enjoy the day full of music

Great job, Jûrgen!
Just a suggestion. Perhaps have your helpers place the speakers on a short dolly for now(height will be somewhat compromised) and take your time dialing them in until you reached your satisfaction. And since you just got these speakers, they might be going through the "rebreak-in" period, which means the sound will continue to change.
