PreSonus Eris Pro 4 4-inch Active Coaxial Studio Monitor (Single Unit)

The PreSonus Eris Pro 4 is an active studio monitor designed for accurate audio reproduction in professional and home studio environments. It employs a coaxial speaker design where the high-frequency driver is positioned at the centre of the low-frequency driver. This single point-source configuration provides superior phase alignment, resulting in a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns. These characteristics make it particularly suitable for both traditional stereo mixing and immersive audio formats like Dolby Atmos. The monitor features a 4.5-inch woven composite woofer for tight, clear bass response down to 55 Hz and a 1-inch ultra-low mass silk dome tweeter for detailed high-frequency reproduction. It is powered by an 80-watt Class AB amplifier. Comprehensive acoustic tuning controls are provided, including three-way Acoustic Space adjustment to compensate for placement near walls or corners, plus continuously variable high-frequency and mid-frequency EQ controls. Flexible connectivity options include balanced XLR and ¼-inch TRS inputs alongside an unbalanced RCA input, allowing connection to various audio sources like mixers and interfaces. The Eris Pro 4 is best suited for music producers, audio engineers, and content creators who require a neutral and detailed listening experience for critical mixing and mastering tasks. Its natural, less fatiguing sound and configurable acoustic tuning make it practical for rooms with less-than-ideal acoustics. The cabinet includes provisions for wall or ceiling mounting, facilitating integration into multi-channel surround setups or space-constrained studios.
