Cambridge Audio’s Aero reinvents the two-way loudspeaker in midrange-friendly fashion with excellent performance and value.
What if you needed two throats to speak? Sounds a bit cumbersome, right? But that’s how a two-way loudspeaker usually treats the human voice. Its drivers divide the midrange frequencies where the voice resides into two parts, sending higher frequencies to the tweeter and lower frequencies to the woofer. While the crossover varies from speaker to speaker, the frequencies that handle the voice usually get split right in the region where human ears are most sensitive to vocal timbre.
Of course, good speaker designers routinely surmount this obstacle to natural vocal sound, either by carefully tweaking their two-way designs or by going to three-way designs that dedicate a separate driver to midrange reproduction. But the three-way approach adds two more crossover sections, potentially leading to other troubled areas of reproduction.
