Is the Box X2 worth it?

For a budget moving-magnet turntable feeding powered speakers, yes. It costs far less than most dedicated phono stages and adds a second input. Skip it if you need moving-coil support or adjustable gain.

Does it work with moving-coil cartridges?

No. The Box X2 is designed for moving-magnet cartridges only. A low-output moving-coil cartridge needs a step-up transformer or a preamp with MC gain.

Can I connect it to powered speakers?

Yes. The output is fixed line level, so run RCA cables to active speakers or an amp and set volume there. There is no volume knob on the Box X2.

What comes in the box?

You get the preamp, a 12V 1.5A power adapter, and the usual paperwork. RCA cables are typically not included, so plan for a set.

How does it compare with the Fosi Audio Box X1?

The X2 adds a 3.5mm AUX input alongside RCA, so it can switch between a turntable and a second source. The X1 is phono-only. Both are moving-magnet designs.

Our take on the Fosi Audio Box X2 Phono Preamp

The Fosi Audio Box X2 is a compact moving-magnet phono preamp that also works as a line-level input hub, with RCA and 3.5mm AUX inputs feeding active speakers. It uses a standard RIAA equalization curve, a 12V 1.5A external supply, and a metal chassis weighing about 0.66 lb. Its main draw is flexibility: you can plug a turntable and a second source into one small box.
