I am using a pair of DIY ProAc speaker and I put them on the top shelf of my Hi Fi rack. The shelf is around 1.5" thick and very solid.
Just wonder do I need to put "nails" underneath my pair of speakers? What difference will "nails" give? I used to put my speakers (old set) on stands ..... wow, the difference is quite significant.
I have heard that putting "nails" underneath the Bookshelf speakers can improve the Base performance. Is that true?
Many years ago, I realised that the sound quality of my AR speakers improved tremendously after I put them on a pair of BBC speaker stands. I know that stands are good for speakers, just that I can't afford to use one now because of the living room setting.
Golden rule of HiFi fever is to try and try and try... My Contour I is sitting on a big stone borad (6' x 1.5') on top of a fixed, low wooden cabinet. Some cheap, heavy duty shock absorbing rubbers (design for washing machine to sit on) were placed between stone and cabinet. Tried brass nail before but sound too sharp with no bass. Tried anti-slip mat that it work much better. Set-up is different that effect should be different. However, those mats are very cheap compared to any HiFi accessory. Worth a try.
One layer only. Too much will cancel off the moving coil action, thus, weaken some frequencies. Should start with just 3 or 4 small pieces at different positions.
However, it still can't compare to sitting on a speaker stand with feet of clearance around...
