Hi Oneinthepipe
I own a pair of Skylan 24D, which is their 2 pillar 24inch stands. I havent noticed any muting of highs after I filled the pillars with sand. In fact the bass tightened and the highs are very smooth. My speakers are Green Mountain Audio Callistos. In my case I filled the two pillars of each stand unequally to prevent any similar frequency resonance.
Is your base plate exactly measured for your Spendors? Too big or too small, esp too small, can affect the sound though mostly the low frequenices
