Presonus Eris E4.5 BT Monitors

Each Eris studio monitor features a woven composite low-frequency driver. The material and design of the 4.5-inch Eris E4.5 woofer provide a more consistent dispersion pattern across the entire frequency range, resulting in less muddiness over time and a cleaner overall sound.

Like all PreSonus monitor speakers, the Eris E4.5 delivers a consistent and accurate listening experience, with a smooth and uniform frequency response that has made Eris monitors popular worldwide. Its compact yet powerful design makes it an ideal solution for limited spaces.

Want even deeper bass? Add PreSonus' powerful active subwoofer, the Temblor® T8, to your Eris E4.5s for a true full-range sound system that fits almost anywhere.

Soft high-end
All Eris monitors are equipped with a silk dome tweeter designed to project sound with a relatively wide dispersion pattern, creating an optimal or sweet spot listening area. The result is a smooth, refined sound that reproduces transient details and high frequencies with great precision.
