Tech Note: Se�ng Crossovers with LS50WII (3 pages) One of the really useful features of the KEF Connect app is the ability to truly integrate LS50WII with a subwoofer. This essen�ally makes the system sound deeper, larger, and more dynamic, without drawing distrac�ng a�en�on to the subwoofer. Performance of the LS50WII midrange can also be improved, as the internal amplifiers no longer have the strain of reproducing low bass frequencies - there is more headroom for the midrange.

Tech Note: Se�ng Crossovers with LS50WII (3 pages) Se�ng up KEF Connect In Expert mode of KEF Connect, there are three se�ngs we need to adjust: High pass frequency This must be selected in order to show the frequency slider. This se�ng applies a high pass filter to the LS50WII speaker, dicta�ng what frequencies are played. Sub-out low pass frequency This filter is the opposite of the high pass frequency. It dictates which frequencies are sent out of the subwoofer output.

Tech Note: Se�ng Crossovers with LS50WII (3 pages) What is a crossover? A crossover is a network of filters which adjust which parts of a signal are delivered to the various drivers in a loudspeaker system. The two main types of filters are LOW PASS filters and HIGH PASS filters. Low-pass filter A low-pass filter allows the signal below the chosen frequency to pass through unaffected. Above this point, the signal begins to be a�enuated (reduced in output).
