Spikes on tower speakers

Why not grind down the current spikes flush with base. Then drill new holes and put in threaded inserts and they will allow you to add feet or iso pods.

Wow, some great ideas here. Replies to some posts:

Can't contact original owner (not the seller to me). He is no longer with us.

Anything involving spike removal is not feasible either logistically or it's beyond my capability or my unwillingness to make this a life commitment.

So how to deal with the spikes. They do not go through the carpet. Can I simply rest sharp spikes on granite or marble? Should I force them into a soft wood base? Should I try something like the Hush Puppies recommended above? Again, this is not about protecting the floor or carpet, it is how to stabilize the speakers that have spikes which can't be removed.

Thank you to everyone for your thoughts and suggestions.

I’d go with the granite/marble but I’d also use the Hush Puppies or your speakers could easily slide off the stone if someone bumps into them.  Or, you could just try the Hush Puppies alone first and see how that works — you can always add the granite/marble later if you want.  I would. 

If you have a concrete floor it's best to get the spikes through to that.  But if the floor is wood or you can't or won't get the spikes through to concrete, stay with granite marble or other stone.  Specific gravity is much higher than butcher blocks so they are less big and ugly for the same stability offered.  I have a huge marble base raised on spikes for all my source and pre-amp gear and it looks great with its white and grey swirly colouring.

Don't use any flexible support under the spikes, they just allow the speakers another layer of movement that will blur your soundstage.

@phil59, turn the speaker upside down get a piece of heavy duty tin foil and press it down over the spikes to protect the bottom of your speakers. Find out if the spikes have a stud that is screwed into the speaker. My guess is they do. 

Take a smallish hammer and lay the head flat on the tin foil and tap each spike from all directions to loosen it the get a Channel lock wrench and use it to unscrew each spike. Now replace then with longer spikes. Use three spikes not four!!  If he used four fill in the rear holes with plastic wood the right color and put the third foot in the middle.

When placing the loudspeaker you have to get the spikes all the way through the carpet and padding to the wood underneath. Hold the speaker steady and using a step stool have your wife press down on the speaker right in the middle with a stocking foot while you hold the speaker and spot. She could stand on it if she has to. That should set the speaker in place and you should be good to go.
