Active DJ Subwoofers

DJs of all experience levels understand how crucial a strong bass line is to a song. An active DJ subwoofer is connected directly to a mains outlet for power, greatly improving the bottom end potentials of the wider speaker system during live usage. A firm favourite of the professional DJ, powered subwoofer speakers are suitable for live events or outdoor performances and nightlife hotspots.

An active DJ subwoofer is designed with both the loudspeaker and a powerful amplifier built inside. This inner-amp allows power to be drawn from a mains outlet, as is the case with almost all active speakers. DJ powered subwoofers help to create a balance between bass, middle and treble frequencies by sharing the sonic workload of most rhythmic music.

Buy DJ Powered Subwoofers

An active DJ sub assists other PA speakers in the live network, enhancing the final sound output during a live show. Creative manipulation of the bass track and having it sit well within the mix is one of the keys to achieving professional-sounding master audio, DJ powered subwoofer speakers help artists to do exactly that. This technique creates a great sense of depth in the music and is a tried and tested method of impressing audiences show after show.

Each of the active DJ subs featured is constructed within a robust cabinet with a defensive grille made of metal affixed to the front edge for extra protection without impairing the sound. Working DJs love to play high-energy, rhythmic music that demands a tasteful balance of treble, middle and bass. Activating DJ powered subwoofer speakers helps to refine and focus these signals much more accurately with the assistance of a mixer.

DJ Powered Subwoofer Speakers

Active DJ sub speakers tend to be quite large in size, as a result, they can be quite awkward to carry by hand, seek the assistance of another when carrying across large distances. All active subs can be placed on the floor or even rigged up high in the trussing of a staged area/arena provided there is a power outlet nearby. Contact the customer services department for some more advice on active DJ subwoofer-based usage.

Some refer to an active sub as a bass bin, this phrase is used commonly in the UK, and audio specialists will generally be aware of what is meant by this. Consider using a mixer during the use of a subwoofer, as mentioned this will help DJs separate signals for a more professional-grade master sound. Too much bass input can cause speakers to distort, consider dropping the bass levels to avoid overloading the signal.

There is such a thing as too much low-end much to the bemusement of many DJs, bass while important, should be balanced and mixed with taste instead of being the track's sole focal point. Overuse of bass is a very real thing, pro DJs maintain the levels of every aspect of their music throughout the show, taking into consideration the listening enjoyment the audience will experience. Bottom frequencies travel great distances from the speaker, making them perfect for outdoor events and other open-air shows.


Frequently Asked...

What is an active DJ subwoofer?

Active DJ subwoofers contain their own power source, featuring an in-built amplifier. This means they do not need an external amplifier, ensuring an easy set-up. As with all subwoofers, they reproduce bass frequencies and provide a rich sound. An active subwoofer typically has in-built mic and line inputs, and volume and equalisation controls on the rear. Some units also have useful functions such as Bluetooth and an in-built MP3 player.


What are the benefits of an active DJ subwoofer?

Active DJ subwoofers have key benefits, making them a popular choice with DJs. The main advantage is they have an in-built amplifier, which means an external amplifier is unnecessary. Therefore, less equipment is needed and the set-up process is straightforward. It also means the driver’s power needs are optimised with the internal amplifier, and they have been designed to work together perfectly.


How do I connect an active DJ subwoofer?

An active DJ subwoofer will need to connect to the rest of your PA system. As no separate amplifier is required, the active subwoofer can connect directly to your DJ mixer/controller, with a signal cable. It will also need to be plugged into the mains power. Your active stereo speakers can then be easily daisy chained to the subwoofer, or alternatively they can also be connected directly to the mixer/controller.


Are active DJ subwoofers better than passive DJ subwoofers?

Both active and passive DJ subwoofers produce an excellent range of low frequencies, enhancing the overall sound. Some consider active subwoofers a better choice as they have an integrated amplifier. This makes the set-up process easier as no external amplifier is needed. In comparison, passive subwoofers need to be connected to a suitable amplifier, meaning extra equipment is necessary. However, an active subwoofer needs to be powered by the mains whereas this is not the case with a passive subwoofer. This means a passive subwoofer can be more flexible if power outlets are limited. Passive speakers also tend to be more affordable and not as heavy, making transport easier.


Does an active DJ subwoofer need an amplifier?

No, an active DJ subwoofer does not require an external amplifier. An active subwoofer features an in-built amplifier that powers the speaker. This ensures a simple set up, as additional equipment is not needed. Once the subwoofer speaker is connected to your DJ mixer/controller and plugged into a mains power supply, it is ready for use.


Which active DJ subwoofer is best for a DJ?

There are many high-quality active DJ subwoofers available and finding the best for you entails considering your requirements. Think carefully about the size, power and features that you need. For instance, a bedroom DJ may suit a more affordable, compact unit, such as a 15-inch 300W subwoofer. Whilst a working DJ may choose a powerful subwoofer pair with 1200W or a bi-amp system to optimise output. Please contact our friendly Electromarket team to discuss the best DJ subwoofer for your needs.


Can I use passive speakers with an active DJ subwoofer?

Yes it is possible to use passive speakers with an active DJ subwoofer. Some active subwoofers have an output for running additional passive full range speakers. Alternatively, the signal output from an active subwoofer can be taken to a power amplifier which would connect the passive speakers. For more information get in touch with our expert team at Electromarket.


What types of active DJ subwoofers are available?

A wide selection of active DJ subwoofers are available, differing in size, power and features. Active subwoofers may have an inbuilt crossover or filter network, and some high end models will also have a bi-amp design, maximising sound quality. We provide both individual subwoofers and active pairs to suit all requirements. The available functions will vary, with some active subwoofers speakers including an inbuilt MP3 player and Bluetooth receiver, enabling audio to be streamed wirelessly from paired smart devices.
