PreSonus Eris 3.5 2nd Gen review

The Eris 3.5 2nd Gen is the budget entry, and at $99.99 for the pair it costs less than half the price of a single Kali LP-6 V2. PreSonus calls it a media reference monitor for bedroom studios, video production and gaming. A 3.5-inch woven glass fiber woofer and 1-inch silk dome tweeter run on 50 W of Class AB power, with a published response of 80 Hz to 20 kHz and 98 dB peak SPL at 1 meter. High and low frequency controls adjust by up to 6 dB to suit the room. Connections are generous for the price: balanced TRS, RCA, a front 1/8-inch aux input and a front headphone jack that mutes the speakers when used, plus speaker wire and cables in the box. A power saver mode engages after 40 minutes. The limit is low end: with nothing below 80 Hz, you will need headphones or the Eris Sub 8BT to judge bass. We compared documented features and published prices; we did not test it.
