Out on the tiles...with speaker spikes.

I'd actually recommend staying away from coins... I had a pair of ProAc RS2s on sand-filled Target R4 stands and the spikes punched through the coins I used... The ProAcs probably weighed, what, like 30 lbs, figure 75 lbs for the stands, maybe 25 lbs of sand (I'm guessing here), so less than 150 lbs total. Nice clean holes right through to the floor, as I discovered when I moved.

You must have used cheap (pun intended) coins. I use British two pound (sterling) coins - they are probably the most expensive coins that one can get. Pbb, I would use the Canadian two dollar coin, but the two metal design would not be as effective (tongue planted firmly in cheek).

Salut, Bob P.

Judit, as we know, there are proper applications for different coin denominations. Obviously you are aware of this, and I was simply mentioning my use of the 25 cent application. However, I would never be "nouveau riche" enough to use 25 cent models, when 5 cent models will suffice. :^)

Edesilva has a good point(ha!) that some very heavy things could punch through the coins. That means that the frugal audiophile will have to resort to "punch outs" from steel electrical boxes, which are about the size of coins, but made from steel. Still cheap and effective.

I don't like to spend alot on certain simple tweaks, because then I can spend more on my new amps, or whatever.

No kidding, pennies sound better than quarters. This experience was actually the first time I knew I was a freak. I could hear the difference between quarters and pennies, and it was similar in general terms to the difference between silver and copper in interconnect and speaker wire. All I could think of was "Omigod, what's next?" I also endorse the Audiopoints products, having used them to good effect under many components. Also, I believe Mapleshade recommends brass cap nuts to put under their footers (upside down to "catch" the point) to protect wood floors.

OK , this may get some flak in response but I used to use pennies under my spikes to protect a wood floor where I lived. They worked very well and they were cheap(about 3 cents). They'ld probably work for your tile floor and if not it won't even cost you a nickle(which you could also try).
