I am using them as an LCR trio with fantastic results. For the center, I have it on a pair of isoAcoustics Aperta 200 stands to get it angled properly, For the L/R pair, I have a custom pair of stands that a woodworker associate of mine put together for me for a modest cost. Those are also on isoAcoustics Gaia II feet, again, mostly for fine-tuning the angling and leveling on my not-quite-even floors. If anyone is interested, I can cough up a schematic diagram for the stands.
Ignore the sliders, they're just in temporarily until we can install the last bits of the AV rack and reposition the speaker. As for the /r/tvtoohigh crowd, the installers refused to put a swing-down mount on the mantel due to the facade weakness, and the seats in the room all recline, so your comments will be preemptively ignored.
