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. 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. Launched in 1995, JBL’s best-selling EON family of PAs set the benchmark for how great a powered loudspeaker system can be.

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. 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. 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.

The real measure of a decent quality sub is experiencing a fuller sound without necessarily taking too much notice of the bass signal. It should always complement and enhance the existing sound as opposed to totally overpowering the system until it sounds very muffled and effectively inaudible. Home Active Sub 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.
