Independent shopping perspective
The Korena take
The Eris Sub 8BT (2nd Gen) is a compact 8-inch studio subwoofer for extending a home or small project studio’s low-end monitoring to 30Hz. Bluetooth adds wireless playback from a laptop, desktop, or mobile device, while TRS and RCA connections support wired 2.1 routing. Its variable 50Hz–130Hz low-pass filter and switchable 80Hz high-pass filter let you set the handoff between the subwoofer and connected monitors, helping keep that division intentional during mix checks.
Strong match
Who this is for
- Home and small project studios that need monitoring down to 30Hz.
- Checking bass and sub-bass content in production, mixing, or sound-design sessions.
- Wireless playback from a laptop, desktop, or mobile device through a 2.1 monitor setup.
