Active subwoofers have the capability to widen the scope of your mix, offering a new level of deepness to the final master audio you require. For reference, think of your active subwoofer as a loft conversion, homes run just fine without conversions but spending a little extra will give you a lot more room to manoeuvre. Relate this to sound design and you'll realise how important an active subwoofer can be, allowing you to explore many different styles of music uninterrupted by distortion. Discover Active PA Subwoofers These PA subwoofers are run by a 64-bit DSP system that manages amplifier gain and cross-over settings, peaks limits and a 294ms / 100m alignment delay. A 5-band parametric EQ and high-accuracy FiR filtering ensures accurate phase alignment and tonal control to suit any environment. With a frequency response of 25Hz to 120Hz, the XW218 provides the deepest of bass from any source. The built-in 5000W Class D amplifier is now in its 3rd generation, proving incredible performance with unparalleled efficiency and minimal thermal waste. With the systems DSP running everything via monitored inputs and outputs, The XW118 has features such as automatic input overload protection, overvoltage protection, and thermal shutdown with a energy saving ECO mode when no input signal is being received. All audio products have useful lives, and JBL engineers are committed to making that lifespan as long as possible—not only in terms of reliability, but in terms of how good the system sounds every time it’s turned on. Subwoofers are great for adding real depth to your live mix, by emphasising the most effective and prominent bass frequencies. In doing so, they alleviate some of the strain on your main PA system speakers and amplifiers, allowing for great clarity in your live mix.

Higher power subs are preferred by many professionals as the larger wattage denotes the overall power of the driver itself. The size of the inner speaker driver does not always mean it is the better choice, this comes down to power and wattage alone. For instance, subwoofers at 600W do not necessarily need to be used six times as loud as a 100W sub, it is just an indicator of the subs potential and not necessarily a finish line so to speak. An active sub will greatly improve your overall sound output, these speakers working to boost the bass signals within your music. Utilising the built-in amplifier, any bass-heavy music will sound far clearer as the low-end frequencies are channelled through the speaker driver. This leaves far more room for your tweeters to deal with the high and mid frequencies, balancing your sound much more professionally. The 8003-AS II features a built-in digital signal processor that comes with a selection of presets so the subwoofer can adapt to the speakers you integrated it in to. Found on the rear is an innovative input patch bay that provides you with stereo XLR inputs alongside an XLR link-crossover with a switchable crossover frequency of 80Hz or 120Hz. The highly efficient 2200w amplifier features a rugged aluminium, mechanical structure that dissipates heat without a fan and stabilizes itself while in transit. With the 8003-AS II, you get an input sensitivity encoder so you can set the input signal level to a volume that suits the situation, the amount ranges from +0dB gain reduction all the way to +99dB of gain reduction. A XOVER section gives you a broad range of 24dB/octave low and high pass filter options which allows you to get the perfect sound for your system. The two main attributes that contribute to portability are the design of the handles and the weight of the unit. An ergonomic design – often with handles inside deep recesses – will allow for much easier carrying.You should get an instant answer on whether your application has been successful, though in some rare cases Klarna or V12 may need to look at the application in more detail. Amate Audios DSPStudio control software for laptops and tablets is capable of adjusting and setting up even the finest details and monitoring key parameters of the XW218 amplifier And then, of course, the lighter the 18-inch subwoofer is, the easier it will be to carry too, but you need to make sure that the speaker isn’t so light that it may move around when the bass is pumping through it. Voice Coil

Avoid placing the subwoofer in corners: While it may be tempting to place the subwoofer in a corner of the room, this can actually lead to unwanted bass buildup and resonance. Instead, try to position the subwoofer away from walls and corners to achieve a more balanced sound. When looking for a subwoofer that can stand up to the elements, you need the JBL Professional JRX218S Portable Stage Subwoofer. With a rugged enclosure that’s designed to withstand the rigors of the road, this subwoofer is built to last. Whether you’re using it for live music or DJing, the best 18 inch subwoofer will give you the power and performance you need. Cast Aluminum 35mm Pole Mount: Subs connected to a television provide a far more effective sonic clarity, a connection is simple to do and it will immediately improve the sound quality of all TV-based entertainment. The above does depend on the quality of your TV, you may have an expensive system with excellent built-in speakers but lesser TVs tend to sound rather tinny, especially during movies. As mentioned, a subwoofer's main purpose is refining bass tones, but coupled with lesser speakers you can get the very best out of your existing equipment by incorporating one into your home. Does a subwoofer need a power source? For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

RCF SUB 8003-AS II Key Features

Please note that this extended warranty is currently only available on products sold within the UK, EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided. As with any sound enhancements, a personal comparison must be made to determine the quality of the sound itself, remember that the appropriate quantity is crucial. A lot of nightclubs or street racers with large subwoofers in the boot of their cars tend to overwork bass frequencies and if pushed too far this can lead to an inaudible humming noise. This is where quantity comes in, you only want the bass to accentuate your mids and trebles as this increases the clarity and volume of sounds. In addition to DEEP DSP algorithm, GuardRail, Auto Standby, balanced line-level XLR input with an XLR "Thru" connector, Attenuation Control and LED indicators, the KLA181 subwoofer also includes a polarity switch. Features A powered subwoofer – also known as an active subwoofer – will include an amplifier inside it, whereas a passive 18-inch subwoofer does not include an amplifier inside the cabinet. Basically, this means that a powered subwoofer is ideal for people who are using a sound system that doesn’t include a third party amplifier, whereas a passive subwoofer is only for people who have an audio system that includes an amplifier.
