Suggestions to place Thiel 3.6 speakers on hardwood floor

My basement will be complete soon with dedicated space as listening room 38'x20'x8'. I have carpets in my current listening area and Thiel 3.6 are placed with their carpet piercing spikes. I have hardwood floors in the basement and would like your inputs placing the Thiel 3.6s. Main issue is my speakers and equipment stand with turntable, have spikes. Appreciate your suggestions to get this done without damaging the hardwood floor and loss of bass response.
