Unity 7.5 or Unity 8.0?

Customers often ask which Wideband model best matches their listening preferences. All models cover both midrange and tweeter frequencies; the differences lie in tuning and sonic character rather than sound quality.
Unity 8.0 delivers the flattest, most neutral response, with minimized resonances and extended high-frequency performance. It is ideal for listeners seeking maximum accuracy and an audiophile-grade presentation.
Unity 7.5 is tuned with a more energetic high end, providing a forward, dynamic sound without harshness. It excels at high-SPL listening and suits genres such as hard rock and metal.

ES-02A and ES-02iB offer a balanced middle ground between neutrality and enhanced treble presence.
ES-02EX (coaxial) follows a Unity 8.0–style tuning, with a smooth, flat response and a slightly brighter yet refined top end.
