What to place under speaker spikes on hardwood

Sorry, I forgot to say that.

I'd avoid coins, unless you want holes in your floor. (Might also tend to affect how you can slide your speakers). ;)

I say this because I had Response 2s and Target R4 stands on pennies, and the target spikes punched right thru (as I discovered upon moving). In other words, don't worry about dulling the spikes.

Marakanetz--doesn't the use of vibrapods sort of cancel out the use of the spikes? I'm no physicist, but isn't the vibrapod theory that they deform and convert energy into heat instead of transferring vibrational energy between two things that are moving at different rates? In contrast, I thought the physics behind spikes is that they couple one object to some reference (i.e., the floor) that isn't moving. I won't argue with your ears if you think your system sounds best with both, but I'm curious...

Spikes dig into pucks. Speakers move around well without harming floor. Sounds fine with my 80 lb. floorstanders.

I found pennies from 1970 to work the best!

Linn Skeets, they are just what you are looking for. ~ $75 for a box of eight.

Coins. Of suitably high denomination to reflect the cost
of the speakers ;-)

Linn makes "skeets" that are designed for this. Thet are heavy round discs with holes in the center for the spikes. (I do not know what they are made of, but they are somewhat heavy for their size.)

I use them and have no trouble sliding my speakers w/o scratching the floor.

I have went the "pennies" route, what a nightmare! Do it right and save yourself a headache!!!

Cut 2 3/4" MDF platforms aquired from the near-by Home Depot so that it's surface area is approximately >=1.5x larger than the cabinete base.
Place this platform on the vibrapods(get 4 per each platform at least) of sufficient quantity and grade. Place your speakers onto these platforms. The whole tweak'n'convenience is just arround $50.

Sound Anchors has a nice product -- check it out at their website.
I wouldn't use the Target discs, if they're the same ones that came with my Target amp stand. I now have four small donut shaped dark marks on my wood floor that won't come off.
I'm using some brass discs slightly smaller than the size of a quarter with a depression in the middle of each for the spike. I think they were being sold at one time by Goldmund for about $4. each, but I couldn't tell you where else to find them.

Nickels for silver spikes or pennies for brass ones!
Don't worry about dulling the points. The force per square inch is still ridiculously high, so the coupling will work.
The teflon sliders MAY work, but I fear they'd wiggle in the low bass, like sorbo-pucks, etc.
Have fun.

You could purchase audio point disks, however they will not allow the speakers to slide without scratching up your hard wood floor. If the product allowes you to slide the speakers around it will defeat the sonic feature/purpose of the speaker spike.

I found "footers" for sale at Audio Advisor which are designed to hold the point of the spike and protect hardwood floors. They came with an adhesive on the bottom covered by thin paper, which will come off if you try to slide heavy equipment, the result being they will stick to the floor. This may be sonically better, but inconvenient. I bought some teflon furniture sliders at Home Depot in the appropriate size, which also have an adhesive side, and stuck them to the bottom of the footers. I have them under my speakers (ML SL-3) and equipment rack, and have not noticed any significant deterioration (or improvement, for that matter) in the sound as compared to the footers without the teflon, but they slide quite satisfactorily. If I glued them to the floor, it might sound better, but I have not been willing to do that.

Target (and other companies) make a product just for this
purpose...unfortunately I don't remember what they're called. They cost $30 for a set of four. They don't slide
around, however.
