Centering System
In a conventional loudspeaker the “spider” – typically a pleated fabric – acts like a spring to return the voice coil (and the cone) back to its starting position, centered within the magnet’s gap. The TNC Solutions Inc. bass driver does away with the spider entirely, instead using a special magnetic fluid in the gap. This fluid provides the restoring force – in the form of magnetic attraction – needed to guide the voice coil and keep it centered within the gap. The speaker is immune to harsh outdoor environments and won’t degrade over time. |
