Spike Decoupling Glider or Fat Glider?
« on: 14 Aug 2017, 11:38 pm »
Several months ago, after buying a pair of 70 lb each ATC two-way active tower speakers, I had a couple of guys from the local high end shop over to fine tune placement of the speakers. The condo floor has a medium depth shag carpet, I assume on a pad with concrete slab underneath and the garage under that. The speakers come with separate spikes that can be screwed in, four each, which the shop guys put in when the set up was done, in part to level the speakers and in part to fix placement (without the spikes, moving the speakers is not difficult, tho not something I would normally do). I've attached a photo of the right speaker to give an idea of the location. A 360 degree view of the spikes and where they are placed (not on carpet) can be seen under the photography tab at http://atcloudspeakers.co.uk/hi-fi/loudspeakers/entry-series/scm19a/.

Having read Jim Smith's recent column in Copper magazine, I'm looking at seeing what decoupling will do.  The first question is, spikes or no spikes? If spikes, then the regular spike decoupling gliders are it.  OTOH, if no spikes, then the questions is, Little or Giant Fat Gliders?  Thanks,
