Overview
Home audio tinkerers and desktop setups get a small mono class D amplifier that switches between subwoofer and full-range duty. It ships with a power adapter and drives most passive speakers and subwoofers.
A built-in low pass filter turns it into a dedicated sub amp, or a switch makes it a full-range mono amp. The advertised power figure needs an optional larger supply, which the listing itself admits.
Who it's for
DIY audio fans and desktop listeners who want to power a sub or a single speaker get a compact, switchable amp. Buyers chasing peak wattage should plan for the larger supply.
Pros and cons
- Switchable sub or full-range mode
- Built-in low pass filter
- Runs cool and quiet
- Power adapter included
- Rated power needs a bigger supply
- Input types not listed
Performance notes
Output depends on the power supply voltage and speaker impedance; the included supply delivers less than the peak figure. The low pass filter strips higher frequencies in sub mode so the subwoofer only reproduces bass.
