Depending on what's under your hardwood floors, spikeless speakers might work well.
I recently sold my ProAc Response 2.5s to a co-worker who after almost 2 decades of being off the merry-go-round has begun building a system again. He had no idea how to install the ProAc plynths and spikes so he just placed the cabinets on his hardwood floors. When I went over to have a listen and help him tweak the placement I was shocked at how stable the speakers were and how great the bass sounded. It turns out he had concrete under the hardwood and the floors were well leveled.
I brought over some brass cups for his speaker spikes, but it turned out they weren't necessary.
