Songs Faber Olympica III

Just got a pair of these speakers. I’ll be setting them up tonight. Hoping that I can benefit from the accumulated wisdom here...

Any tips from current owners? Setup, positioning, burn-in (although mine were previously owned, so burn-in shouldn’t be an issue), spikes versus no spikes (mine are on hardwood floors in the basement, meaning there's a concrete slab underneath), etc.

(I do know that I have the choice of positioning them so that the ports will either face outward or inward, and I glean from reviews that I should try it both ways to see what sounds best in my room.)

Any tips are greatly appreciated.
