Gemini HW-B400F/ZA 2.0 ch Soundbar with Built-in Subwoofer (2025)

2.0 Channel Soundbar System

The Gemini HW-B400F/ZA delivers a 2.0 channel audio system with a built-in subwoofer for home entertainment setups. A 6.5 inch driver handles low frequencies down to 27 Hz while the soundbar projects audio across the listening area. The compact metal cabinet measures 4.72 by 4.72 by 0.98 inches and fits on most media units. It suits viewers who want richer TV sound without separate speaker placement.

40 Watt Power and Passive Operation

The unit draws 40 watts from a corded electric supply and uses a passive driver design without internal amplification. No fan or active cooling is present, so operation stays silent during playback. The metal enclosure helps dissipate heat from the driver during extended use. Buyers needing higher output levels or active room calibration will need a different class of product.

Samsung TV Remote Integration

A Samsung TV remote can control power, volume and sound-effect modes through HDMI-CEC, removing the need for a dedicated handset. Surround Sound Expansion widens the perceived soundstage while Voice Enhance Mode lifts dialogue frequencies for clearer speech. A Night Mode reduces bass and overall volume for late-night viewing. Households without a compatible Samsung TV lose the single-remote convenience and must use the soundbar's own controls.
