Hi, I own a pair of 1 meter high speaker stands for my bookshelf speakers, which each have 4 pillars. Im planning on filling each pillar with sand inside a stocking to make for a more solid platform for my speakers. Ive heard that as well as providing a more solid platform, this should also enhance sound/bass quality. Queries: Is filling my speaker stands with sand really likely to improve sound quality?. Is there a certain amount of sand I should be filling my speaker stands with? (ie half way, 3 quarters or full). Thanks. Alex.
