Internationally acclaimed, and in our opinion completely justified!
It increasingly appears that spikes under speakers decouple well, but also cause strong feedback that is audible in the playback.
Conducting or guiding the energy provides much less feedback and results in a more open, looser and better-defined sound image from your speaker.
On wooden floors with a hollow bottom, the Gaias also provide a significant improvement in the bass reproduction, which becomes less 'boomy' and has more detail.
Choose the right model that matches the weight of the speakers.
