We take a look at the 6 best subwoofers available today and find out why you really need to invest in a good PA subwoofer if you want the best sound out of your PA system
Whether you’re a venue owner, small pub or club owner or a travelling DJ, chances are you’ve got a set of PA speakers as part of your rig. But how many of you actually decide to invest in a good quality PA subwoofer? And do you understand the benefits of actually using one? Well, today we’re going to discuss the benefits of using a PA subwoofer and highlight our top 6 best subwoofers to give you a good idea of what types are out there and why you should invest in one if you want the best sound for your set up.
Do I need a Subwoofer?
We’ve already discussed the importance of using a subwoofer if you’re a producer, but right now we’re going to discuss why pub/bar owners, DJ’s and the likes of cover and wedding bands should add one to their own PA set up.
If you’re asking yourself “Do I need a subwoofer for my PA system?” chances are you probably do. Compact speaker PA systems do a great job of providing you with all the sound you need on stage and filling a room with your music or whatever it is you’re playing through them, but unfortunately some of them just can’t get to the lower frequencies anywhere below 32 Hz before the low frequencies roll off – not ideal if you want a full frequency bandwidth. If you’re a DJ this is not ideal, as all the bass sounds you’ve worked so hard on are not as good as they could be. As a wedding band, your bass sounds and kick drums will lack that life you need to sound your best.
If you’re lacking bass in the mix, or your PA speakers distort when you drive the lower frequencies, you’re obviously in need of a subwoofer.
A subwoofer fills in all those low frequencies that are missing from your mix and is dedicated to providing your sound with the deep bass that may be lacking from your sound. As almost all PA subwoofers solely produce the bass tones and never the midrange or high frequencies (with very few exceptions) this allows you to enjoy completely concentrated bass tones and accurately reproduced low-end energy within both live and recorded music.
Main PA speakers are often driven to their limit, so adding excessive bass into this mix will usually result in a distorted sound. So, it’s best to invest in a dedicated subwoofer, this way you have complete control over the bass via a separate speaker and can even place your subwoofer in the best area of the room for optimal bass sound.
Essentially you need a subwoofer if you want to enjoy the lower frequencies in your music accurately, you don’t want any unwanted distortion when driving your PA system’s bottom end and you want complete control over the bass frequencies. If you’re in a cover band, you’re DJ or you’re a venue/club/bar owner, a subwoofer is a must.
So show me the top 6 best subwoofers!
We’ve compiled our favourite options here to bring you the best subwoofers in price ascending order. These range from PA subwoofers ideal for small touring DJ’s and live bands to options that would be ideal for club and bar owners, all the way to festival organisers. They’ve also made our best subwoofers list thanks to their ease of use, high quality sound and reliability.
1. QSC KS212C Cardioid Active PA Subwoofer
First up we have the QSC KS212C Cardioid Active PA Subwoofer, which is the most powerful active subwoofer we have in this list. You have a 3600 Watt Class-D amplifier module at your disposal, pumping out your music through dual 12-inch, long-excursion drivers via a dual 6th order band-pass design– your audience is going to “feel” the bass as well as hear it.
A very useful Scenes collection encompasses a range of settings for commonly-used applications ensures you're ready for a variety of different environments. Whilst the fact you can place it in vertical or horizontal positions or fly it via the M20 speaker pole fittings in either position make sit a great option for portable or static systems.
A rugged, robust, and lightweight ABS material makes it a solid, roadworthy companion for travelling musicians and DJ’s too. One of the best subwoofers for PA systems that need to be loud!
2. Alto TrueSonic 3 TS315S Powered Subwoofer
The Alto TrueSonic 3 TS315S Powered Subwoofer is ideal for both touring acts and venue owners thanks to its epic Class-D amplifiers, 15” Driver with High-Temperature, Long-Throw Voice Coil and huge 2000 W peak, 1000 W continuous output power. The interesting thing about this model is its cabinet. The cabinet is designed to be virtually acoustically perfect so not only is it strong, but also resonant-free. This means the Alto TrueSonic 3 TS315S absorbs less sound, trabnsferring it to teh crowd instead – you can rely on it even in the most crowded rooms. The added thermal protection and transducer overdrive protection means nothing is going to stop your show.
You can pair the Alto TrueSonic 3 TS315S with any speaker system effortlessly and utilise the 2 x XLR/1/4" Combi Jack Inputs with 2 x balanced XLR Line outputs to create your ideal PA setup. Although slightly heavier at 35.6kg it is capable of touring with you thanks to the rugged construction, but it would ideally sit static in a venue or club. Big power, a 15” woofer and 3” (76 mm) voice coil and max SPL of 131 dB, makes this an extremely powerful, but still affordable PA subwoofer.
3. Yamaha DXS12 Active PA Subwoofer
The Yamaha DXS12 Active PA Subwoofer is one of the best subwoofers available thanks to its compact size and immense capability. The 12” active subwoofer makes a great option for small to medium size venues as its capable of producing 950w of pure bass power – more than enough for venues, DJ’s and pubs.
The Yamaha DXS12 Active PA Subwoofer features a high-efficiency 950W Class-D amplifier as well as a 12" high-output woofer that brings out a surprising amount of bass considering its small and compact size and allows you to select from 3 different bass settings depending on your needs, your environment or musical taste. The NORMAL, BOOST and XTENDED LF settings give you a choice of a balanced low-frequency (Normal), a boosted and tightly focused bass (Boost) or a dropped low-end frequency for those super low bass lines and sub drops (XTENDED LF). This basically means you get an extremely powerful subwoofer that can cater to a wide range of different scenarios – ideal for professional musicians and venue owners.
Although they’re designed to accompany the DSR and DXR PA speaker systems, the DXS12 Active PA Subwoofer will easily integrate into your existing PA set up and provide you with high quality bass sound wherever you decide to place it.
4. RCF SUB 705-AS II Active PA Subwoofer
We're getting into the realms of larger venues and outdoor shows with the RCF SUB 705-AS II Active PA Subwoofer as it’s packed with a 1400 watt digital amplifier pumping out sweet bass through a 15” high power woofer with 3” voice coil. If you want your bass lines to be felt, then this is one of the best PA subwoofers for under £1,000. The RCF SUB 705-AS II has been specifically designed with superior SPL levels for outdoor and long distance, so live gigs are more than easily covered.
There’s a built-in digital stereo crossover with adjustable crossover frequency which means you can set it up as a sub-satellite speaker system and integrate into your RCF PA setup or any other PA system you might have already.
You have plenty of control and connectivity options with a LINK/XOVER OUT SWITCH which will high pass the output link when engaged, an XOVER Switch that sets the crossover frequency of the output at 80 Hz or 120 Hz as well as a PHASE SWITCH that can reverse the phase of the output signal, keeping your system sounding great. There’s also a Stereo XLR input, Stereo XLR signal outputs and a limiter Status LED that will keep your system safe.
A max SPL of 131 dB, 40 Hz ÷ 120 Hz Frequency response and 1400w peak total power will be more than enough for most clubs and venues, whether indoors or outdoors.
5. Bose F1 Subwoofer
If you don’t have a lot of room but need a lot of power, the Bose F1 subwoofer is a great choice, especially if you’re planning on coupling it with the Bose F1 Model 812 Flexible Speaker Array to create a complete, highly portable PA system!
However, if you just need a sub that you can take everywhere with you, the Bose F1 Subwoofer is great on its own or as part of your wider set up thanks to its easy to carry construction and compact design, making it ideal for houses of worship, mobile DJs, schools and even business presentations.
Again, its best paired with the F1 speaker array, so we’d suggest using it with that, but it makes our best subwoofers list thanks to the fact it’s got 1000 watts of power ready to pump out the bass via 2 x 10” high-excursion drivers – you’ll be surprised at just how well this sounds considering its smaller size (27” H x 16.1” W x 17.6” D (688 x 410.16 x 448.5mm).
A polarity switch helps correct the low frequency overlap between your speakers and sub whilst the Line Output EQ allow you to set the F1 sub’s output to high-pass filter or full range, meaning you can select crossover options a lot easier. In addition, this is a 2 input and 2 output sub allowing you the option of using 2 speakers and 1 sub for a complete venue worthy sound. Great Bose sound in a small and compact box.
6. QSC KW181 Active Subwoofer
Finally, we have the QSC KW181 Active Subwoofer which is one of the most powerful subwoofers available, and by far the toughest. With this model, you have 2000 watts of pure power at your disposal, making it an ideal choice for venues and festivals and one of the best subwoofers for church sound systems too. The QSC KW181 Active Subwoofer has a max SPL of 135dB as well as a woofer size of 18”.
It's pole mountable, light enough to be part of a portable PA system at 83 lb / 37.6 kg and has a frequency range of 37 Hz to 129 Hz making it an extremely capable subwoofer that can cater to a wide variety of sounds. Whether you're busting out huge basslines and EDM music or you want to be able to hear all the subtle nuances of "Lady In Red" from a distance, this thing will handle anything you throw at it and keep your sound clean, clear and concise.
However, it’s the rugged construction and 6-year warranty that will appeal to travelling musicians and venue owners. The QSC KW181 sub is made from birch plywood that allows for greater resonance and protects all the drivers and inner workings whilst the rugged powder-coated steel grille keeps your speaker safe at all time – perfect for those who will be moving the speaker around a lot. In addition, QSC have provided owners with a 3-year warranty that can be extended with an additional 3 years once registered, making it a great choice for club and pub owners that need that extra peace of mind – that’s 6 years of cover!
If you want a totally professional set up that can be both a static and highly portable option, the QSC KW181 Active Subwoofer won’t let you down and will keep your music sounding great at all times.
