Woofers that deliver a cleaner overall sound.
Every Eris-series studio monitor utilizes a woven composite, low-frequency driver. The weave and nature of the Eris E3.5’s 3.5-inch woofer result in a more constant dispersion pattern throughout the frequency range, resulting in less time-smeared audio and cleaner overall sound.
Smooth high-end and wide sweet spot.
The Eris E3.5 is equipped with a one-inch silk-dome tweeter that produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide dispersion pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear everything accurately.
Features
