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. 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.

Rubber feet are an important consideration for the stability of the speaker. Metal corners, as well as a metal grille (preferably made from steel), will also ensure that your 18-inch subwoofer is heavy duty and won’t break or be damaged easily. Portability Collection and delivery costs are included for the first 2 years in the event of an item becoming faulty

Tech spec

Active subs will boost the lower frequencies in your sound without needing a separate amplifier to do so. As the amplifier is already built within the sub, these systems deepen your low-end sound output while simultaneously taking the strain off your tweeters for a well-rounded, balanced sound. We offer a variety of Active Subwoofers from brands such as Studiomaster, Vonyx and Power Dynamics, in sizes from 12 to 18 inches. Buy Active 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. Sometimes, a little extra low-end goes a long way. Our selection of subwoofers will have your trousers flapping in no time! 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.

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. Experiment with different positions: Depending on the layout of your space, you may need to experiment with different positions to find the best placement for your subwoofer.

One of the features of this subwoofer is its ability to handle high temperatures. The subwoofer features a dual voice coil design to dissipate heat more effectively. It can play louder and longer without overheating. This 18 Inch Skar subwoofer also features a high-mass spider design that helps to keep the cone stable at high frequencies and prevents it from flexing or distorting. Exceptional Sensitivity: The EON700 Series leverages the latest acoustic science, transducer designs, cabinet materials and advanced DSP and control technologies to deliver extraordinary performance in a fully professional, highly flexible, easy to use, portable system. Keep the subwoofer on the ground: It is generally best to keep the subwoofer on the ground, as this will help to create a stable and secure foundation for the unit. This can help to minimize vibrations and unwanted movement that can affect the sound quality.

Only passive subwoofers need a separate power source, their active counterparts already have one built inside. Passive subs must be connected to a separate power amplifier to work efficiently whereas an active subwoofer draws its own power directly from the mains.In an installed application, multiple KLA Series loudspeakers can be "daisy-chained" for total gain control from a single remote pot wired to the on-board Phoenix-style connector. Additional power module characteristics on KLA include a balanced, line-level XLR input in parallel with an XLR "Thru" connector, powerCON In and Thru connectors, Attenuation Control and LED indicators for Signal and Limit, as well as discrete LED indicators for Power/Standby status. 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.
