Please bear with my and my meanderings. ok I have some wd25T speakers, roughly 1m high x 29cms width x 27cms deep ( see Avatar). Quite hefty and I have always had them on spikes. I fancy having them a bit higher so thought of building plinths. Entrance my old Heybrook hbs1 stands which some may remember were flat pack jobs, heavy box tube open plan things base with outrigger feet 30 odd cms verticals and top plate all well bolted together with Allen head m8 screws. Very, very solid things. So I decided to just use the spiked outrigger base under my speakers to see what happens and I rather like the effect of an extra 2 inches height. So am now thinking of what to use as short column verticals. I think of solid steel bobbins first but then I think of Townsend speaker platforms and think why not try some quality springs in the four corners Retained by longish bolts, washers etc. My question is how to calculate the forces involved to specify 4 springs from a supplier suitable for this. Is it just the weight of the speaker divided by 4 ? I am no engineer and have no idea about how bouncy the springs should be. Can anyone help ?
