Generally negative
Comparing two Sub10 MK2 units revealed differences in front plate, screws, logo size, text font, and an extra graphic line, indicating variation across production runs. A separate comment also noted rubber feet sticking to paint from over-tightened screws, another minor build quirk.
Generally negative
A user reported their unit buzzes when powered on without music playing, which led them to switch it to standby rather than leaving it idle. This is a noticeable quirk for anyone who likes to keep gear powered between sessions.
Frequently criticized
One commenter felt the Sub10 is too expensive given how low it actually extends, wanting deeper than 20Hz at that price point. This points to a value mismatch between cost and perceived bass depth for at least one buyer.
