Product information

Description

The Edifier R12U 4W USB-powered bookshelf speakers are compact 2.0-channel speakers designed for PC, notebook and laptop use. With a single driver per speaker and a total RMS power of 4 W, they offer clear playback across a frequency range from 30 Hz to 20 kHz. These wired speakers include a 3.5 mm auxiliary input and a simple front-mounted volume knob. Their small footprint and angled enclosure make them suitable for limited desk space while delivering improved bass response via a bass reflex port.

Advantages

Compact and portable design powered by USB, requiring no external power adapter. Balanced sound with enhanced low-frequency response thanks to a bass reflex port. Straightforward control through a single volume on/off knob and flexible wired connectivity via a 3.5 mm auxiliary input compatible with phones, MP3 players, tablets and computers. Available in black and grey to match different desk setups.

Suitable for

Desktop computers and home office setups
Notebooks and laptops without external speakers
Students or users with limited desk space
Listening to videos, web browsing audio and casual music playback

Key specifications

Audio channels: 2.0
Total RMS power: 4 W
Frequency response: 30 Hz – 20 kHz
Connectivity: Wired, USB power and 3.5 mm auxiliary input
Driver configuration: Single driver per speaker with bass reflex port
Colours: Black, Grey

How to use

Connect the speakers to a computer or USB power source using the included USB cable to supply power, then connect the audio source to the 3.5 mm auxiliary input. Use the front volume knob to switch the speakers on or off and to adjust playback level. Position the angled enclosures on your desk so the drivers face the listening position for optimal clarity.

Usage recommendations

For best low-frequency performance, place the speakers on a stable surface and allow a small clearance from the rear or side walls to benefit the bass reflex port. Use the 3.5 mm input for direct wired connections to phones or portable players to avoid latency from wireless adapters.

Specifications

Bluetooth: Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.: No
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
RMS rated power: RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplifiers and loudspeakers.: 4 W
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: PC
Audio output channels: An audio output channel is an electric circuit which acts as a path for a signal produced by a device. A device may have several audio output channels.: 2.0
Number of drivers: The quantity of drivers, which are individual transducers that converts electrical energy to sound waves.: 1
Product colour: The colour e.g. red, blue, green, black, white.: Black, Grey
Speaker placement: The position of the speaker.: Tabletop/bookshelf

Amplifier

Signal-to-Noise Ratio (SNR): This is the ratio of signal intensity to noise intensity.: 85 dB
Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 0.5 %

Performance

Bass reflex: Type of loudspeaker enclosure that uses the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a typical closed box loudspeaker or an infinite baffle mounting.: Yes
