How To Connect A Subwoofer To An Edifier r1280dbs Speaker?

L/R jacks for connecting a subwoofer

Anyone looking to connect a subwoofer to an active speaker, such as an edifier r1280t subwoofer, must make sure that the speakers have a subwoofer output on the back, also known as a Low Pass Filter (LPF) output, an RCA single or paired jack.

On edifier speakers, there are L/R jacks for connecting a subwoofer.

There are several ways to connect subwoofers; one standard method is to use an amplifier or receiver with a dedicated line-level output for the subwoofer and direct a higher-level amplified signal to the main edifier speakers.

To connect the subwoofer to the AV receiver, connect the RCA cable from the receiver’s sub-output to the subwoofer’s line input.

When you connect a pair of speaker cables from the receiver outputs to the subwoofer, followed by another pair from the sub outs to your speakers.

This will send the signal to your main edifier speakers without having any more effect than going through the connectors.

A high impedance electrical circuit inside the subunit picks up the signal, possibly with a low pass filter, and feeds the sub’s amp(s) to drive the sub speaker.

As a result of these sub-out ports, you can easily connect the R1280DBs to your subwoofer as well as other speakers. It has a wide range of inputs that allow you to connect to all types of sound systems, including optical and coaxial inputs.

The Edifier speakers Bluetooth feature, on the other hand, can detect the subwoofer and automatically activate the digital crossover. This input provides lossless sound quality while saving time on cable changes.

Some subwoofers can also be connected using an LFE cable or in a stereo pair with both white and red RCA connections. 

If you don’t have an A/V receiver, you can use an amplifier with a subwoofer output instead. Connect your subwoofer in the same manner by connecting the amplifier’s output to the subwoofer’s line output with an RCA cable.


Besides Subwoofer RCA cable, there are also various types of methods through which you can connect a sub to the edifier speakers. Some are mentioned below!

1-Sub-Out Input: 

A sub-out port on the receiver is designed to send only the bass frequency in the audio signal to your subwoofer.

Your edifier speaker’s “Sub Out” port on the back panel also has a detection function. When the port is linked to an external subwoofer, the speaker’s own bass is reduced, and the connected subwoofer primarily provides the bass.

2-Optical / COAXIAL Inputs:

To ensure lossless sound quality, optical and coaxial inputs are used to connect the subwoofer to the speaker.

You can switch to optical/coaxial mode by pressing the input dial on the side panel of the active speaker or the OPT/COAX button on the remote control; the red light indicates that COAX mode is activated.

Using a fiber optic audio cable or a coaxial audio cable, connect the audio source to the OPT / COAX input port on the back panel of the edifier speaker. Then, play music and adjust the settings to your particular taste on the device.

3-Wireless Remote: 

A wireless remote is more helpful in activating connections such as Optical or COAX mode, Line-in mode, and Bluetooth mode. It is also used for simple volume control and sound field extension.

4-Line In Mode

To switch to Line in 1 / line in 2 modes, press the LINE1/2 button on the remote control; a single flash of the green light indicates Line in mode activation.

Hook up the audio source to the Line In 1 / Line In 2 input port on the back panel of the edifier speaker with the help of an audio cable.

Play music from the connected device and adjust the settings to your preference.

5-Bluetooth Mode

This Edifier r1280dbs bookshelf speaker has Bluetooth connectivity, which adds a modern touch. With its premium design and wireless connectivity, the speakers can be placed virtually anywhere in the house without sacrificing style points.

The Edifier r1280dbs Active 2.0 Bluetooth Bookshelf speaker has a button on the remote control that allows you to switch to Bluetooth mode, which illuminates the blue light.

Configure your Bluetooth device to look for and connect to EDIFIER R1280DBs. If a connection is required, the pin code is 0000.

The Edifier R1280DB includes an AUX port to round out the connectivity options as standard in most speakers. You can even use the speaker cable RCA to add subwoofers to your existing 2.0 system and improve your audio experience.

What Are The Speaker Outputs On My Subwoofer?

It is a connection for use with a stereo amplifier or receiver that lacks a subwoofer output. They connect your edifier speakers to your subwoofer.

Subwoofers with speaker outputs are also likely to have speaker inputs.

Rather than connecting it to a dedicated subwoofer output on the surround sound receiver, you can route your regular speaker cables through the subwoofer and then to the edifier speakers.

In this case, the sub crossover will extract the extremely low bass frequencies that you want your sub to handle while passing higher frequencies to the speakers.

However, an amplifier does not require a sub-out port because it is installed in Line with existing components.


So connecting the subwoofer to the speakers is a breeze. Get a pair of active loudspeakers with subwoofer output, such as the EDIFIER R1280DBs.

By following all of the connections mentioned above and processes and adjusting the filters, you can create the connection and enjoy the nice bass coming from the sub.
