speaker spikes versus better bass on Lore

Got myself Tekton Design Lore just recently, before that was using Audes 037. Not because I was unhappy but just decided to try following rather impressive trails here on the subject of Lore.
What I am hearing so far with Lore is - if I don't but the spikes (came with the speakers) they sound 'boxy' or 'hollow', if I do put the spikes - the bass goes away. I have the hardwood floor (apartment), under the floor there is no foundation (no concrete), so the floor is pretty flexible.
I have not used spikes on Audes. Though those are pretty old model they sound above Lore at least as far as the lower part goes. And from Lore reviews I am thinking I am not doing something right. I am not yet into bass room treatments, I never had to install those with Audes, those gave me very well defined bass so I am thinking I may not be doing something right as far as spikes go. Would love to hear from the elders of the tribe what I can do better.
Regards
