I recently bought a set of your Cone/Spike Decoupling Gliders to use with my Von Schweikert VR4jr speakers, primarily because I wanted to reduce the slight bass boominess I get from my speakers in my room, which I was unable to eliminate by speaker positioning. What amazed me was that in addition to the improvement in bass, the improvements to the rest of the frequency spectrum, in terms of soundstage, clarity & airiness was of a magnitude 2 or 3 times more than the bass. Needless to say, I am delighted with your Cone/Spike Decoupling Gliders.
What I would like to enquire is the point made in your website where you stated that these Cone/Spike Decoupling Gliders would work best if the speaker spikes are solidly & firmly coupled to the speaker cabinets. Would you say that this is a key requirement for the arrangement to work well? The reason I ask is that while the spikes on my speakers are locked in place by the locknuts, the threaded inserts into which the spikes are screwed into are not solidly anchored in the speaker bases; probably due to wear & tear. Would you say it is a worthwhile exercise to try to solidify the mounting of the inserts in the speaker bases?
Thanks for any advise you can give.
