"What are those? All drivers on the ($80K) High Fidelity Cables Baffex 12 come with the patented Surreal Acoustic lens. These devices help with sound dispersion. Drivers due to their shape create a self-canceling vortex. This vortex is similar to a smoke ring it creates a huffing sound that affects all frequencies. The acoustic lens effectively cancels this acoustic distortion. It gives a more live and realistic sound with better clarity and improved distortion, it also images better and has a wider dispersion for those not in the direct sound stage sweet spot."
