I have a pair of Quadral Chromium Style 6 floorstanders which sound superb, but they are not very stable as the supplied plinth isn't any larger than the cabinet itself and there are no inserts in the plinth to fit any spikes either.
So, I was browsing ebay yesterday and saw a "stability kit" for the Style 8 model for two hundred and forty nine chuffing quid Four lengths of flat bar, a set of spikes and some bolts cost nowhere near that so I ordered these and a set of 6mm inserts and a tap set to put the spike threads into the bar, which in total cost twenty three quid including postage.
The aluminium bar will come in one long length which will be cut into four lengths of 250mm each, then drilling out 16 holes, then tap 8 of the holes to accept the spikes. I am OK with that, but having no drill press or a vice I am a bit concerned that my drilling stays true during this operation.
I am normally rubbish at DIY but knowing that I am saving £220 by having a go myself, at least I feel motivated enough to do it
