My new speakers are 190lbs each and come with heavy duty spikes, not so good for my hardwood floor.
What type of spike protection do you suggest?
None, you should never spike into a suspended wooden floor, as the floor is then coupled to the speaker and becomes an "added sound board for the bass", which muddies and woollies up the bass, you only spike into slab cement floors.
For suspended/wooden floors you should always de-couple (not couple) the speaker to it.
Remove the spikes and use these Sorbothane Isolation (de-coupling) Pads under your speaker under the speaker.
