Couldn't find an appropriate forum for this so I thought I put it in this one. Forgive me if this is not in the correct forum. Just purchased metal monitor stands for my monitors. I previously had the monitors on bookcase shelves. At that time used the sound isolation pads. the quesiton: will I still need the isolution pads on the metal monitor stands?
thanks

It depends fully on what kind of metal stands you have. If you think the resonances are affecting the sound, you most likely need to isolate either the loudspeakers from the stands or the stands from the floor.
 
Or are the stands attached to the wall? Or are they on the table? Are the speakers attached to the stands with screws or are they standind free? Hard to answer without knowing the situation.
 
If the stands have metal spikes serving as feet, you most ikely don't need any further isolation.

As noted above, but ideally your stands will have both floor spikes and speaker spikes.  If they only have floor spikes or no spikes then the iso pads will give some isolation.
 
How heavy are the stand?

Thanks for the input..the stands are about 15 pounds and have an 18 inch triangular base with metal spikes that will set on carpet. Top is nine inch square with no spikes. I have a sub with my speakers so the speakers are not reproducing frequencies below 80.

Do these stands allow you to fill their columns with a dense material such as sand?
 
Mine do and this adds to the mass/weight, allowing for even more isolation

+1, which was why I asked the question
 
I would suggest that you use the iso pads or Blue-Tak and six small coins three on each side.

It cant hurt, and can only help. Some stands are made to absorb the vibration and some or not. But just to be safe, use them.

I agree, it can't hurt, the only thing with the ISO pads I have now, my monitors sit a few more inches higher than I'd like... 

The ISO pads that I use allow you to angle the cabinets downwards so that the tweeters point at your ears.

Do you NEED them? Probably not. I'm of the opinion that you're better off with the speakers in direct contact with a solid, heavy stand. Even if the pads actually do something useful (I've seen no hard evidence that they do, only anecdotal), I would think that having the tweeters at ear level is more important.
 
Lest I be accused of hypocrisy, I do admit to having pads under my speakers. However, because my stands are home-made I was able to build them a couple inches shorter to compensate for the pads' height. Also, my stands are wooden and perhaps a third as massive as a quality steel stand and 1/10th as massive as a sand-filled stand (or Jeff's concrete planter stands). Fortunately, they sit directly on concrete so even if the stand vibrates those vibrations stop at the floor.
 
Here's a thought. If your stands have spikes at the base, you might consider removing them. This would lower the speakers 3/4"-1". While I have some doubt about the efficacy of pads, I have no doubt about the uselessness of speaker and speaker stand spikes.
