FIFINE Speakers

1️⃣ An audio signal (electrical current that varies in strength and frequency) travels from your device to the speaker.
2️⃣ The signal passes through a coil of wire wrapped around a magnet, creating an electromagnet that strengthens and weakens with the audio signal.
3️⃣ This electromagnet is attached to a speaker cone, which moves back and forth rapidly in response to the changing magnetic field.
4️⃣ As the cone vibrates, it pushes and pulls air, creating sound waves that travel to your ears
5️⃣ Higher frequencies cause faster vibrations (higher pitch), while lower frequencies cause slower vibrations (lower pitch)

Yes. FIFINE speakers A20, A16, and A22 all support RGB controllable function. You can get the RGB color you like by the RGB button and some kinds of lighting modes can jump following the strong music.

Follow the 83% rule. Place your speakers at a distance from the listening position equal to 83% of the room width. This distance helps create the best soundstage and imaging for stereo listening.

Example: If your room is 4 meters wide, position speakers at approximately 3.3 meters (4 × 0.83) from the listening sweet spot.

Also, you can refer to these tips:
🟣 Height – Tweeters should be at or slightly above ear level when seated.
🟣 Angle – Point speakers slightly inward toward the listening area (about 15-30 degrees).
🟣 Distance from walls – Leave at least 1-2 feet of space, as this causes bass buildup.
🟣 Symmetry – Position speakers symmetrically on either side of your listening position for balanced stereo sound
🟣 Away from corners – Corner placement exaggerates bass and creates dead zones

Stereo is generally better for speakers because it uses two channels (left & right) to create a wider, more immersive soundstage, especially for music, movies, and games. Mono uses a single channel and sounds more centered and less dynamic.

FIFINE speakers are all designed with stereo mode, so you will have a richer, more immersive sound, while a mono speaker provides simpler, centered audio.

FIFINE speakers can easily connect to computers, monitors, mobile phones, tablets, or projectors. The A20 uses USB and 3.5mm cable interfaces, while the A22 speaker supports OTG input, optical input, AUX input, and Bluetooth mode. The A16 wireless Bluetooth headphones also support a 3.5mm interface. Therefore, FIFINE speakers can support multiple different devices.
