Critic Reviews

PreSonus Eris Sub 8BT review: Big bass, small price | Tom's Guide

tomsguide.com

The PreSonus Eris Sub 8BT packs a punch for its compact size, delivering strong bass and mid-range performance that can enhance both music and movie experiences. Its Bluetooth connectivity offers flexibility, allowing connections to a range of devices, from smartphones to traditional stereo systems. However, users should be aware of some hiccups with Bluetooth pairing and the absence of a control app for tuning—features that competitors like the Sonos Sub Mini provide. While it excels in sound quality and customization options, the lack of a comprehensive app and occasional connectivity issues may hinder its appeal for some audiophiles. Ultimately, it's a solid choice for casual listeners seeking an affordable subwoofer solution.

With its compact design and Bluetooth connectivity, the PreSonus Eris Sub 8BT delivers impressive performance for music production and casual listening alike. Its strong build quality and flexible controls offer great value for the price, making it suitable for small to medium-sized rooms.
