Among these is the crossover frequency (low-pass). Now, to perfectly match your KS active subwoofer with your top active loudspeakers, you need to choose a suitable crossover frequency (80 or 100 Hz) \u2013 and apply the correct setting to both subwoofer and top loudspeakers. However, what happens if you don\u2019t? Well, let\u2019s look at it:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"a\"><li><strong>Subwoofer set at 80 Hz, top loudspeaker set at 80 Hz<\/strong>: very good summation of both responses, with powerful bass. Additionally, the low 80 Hz crossover setting reduces low frequencies localization cues.<\/li><li><strong>Subwoofer set at 100 Hz, top loudspeaker set at 100 Hz<\/strong>: smooth crossover summation as well as additional headroom for the top loudspeaker, which reproduces a narrower audio bandwidth.<\/li><li><strong>Subwoofer set at 100 Hz, top loudspeaker set at 80 Hz<\/strong>: now both units are reproducing the same energy between 80 Hz and 100 Hz, generating extra bass level.<\/li><li><strong>Subwoofer set at 80 Hz, top loudspeaker set at 100 Hz<\/strong>: the crossover region will not display a flat, smooth frequency response. There will be a notch of -5 dB centered around 90 Hz, which will translate to a loss in bass reproduction.<\/li><\/ol>\n\n\n\n<p>So, the appropriate adjustment of your crossover is important to get the best out of your QSC active subwoofers and loudspeakers.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"690\" height=\"703\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image.png\" alt=\"\" class=\"wp-image-2536\" srcset=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image.png 690w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-294x300.png 294w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-48x48.png 48w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-250x255.png 250w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-550x560.png 550w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-177x180.png 177w, https:\/\/blogs.qsc.com\/app\/uploads\/sites\/3\/2020\/09\/KS-Series-Rear-Panel-Image-491x500.png 491w\" sizes=\"(max-width: 690px) 100vw, 690px\" \/><\/figure><\/div>\n","protected":false},"excerpt":{"rendered":"<p>All three KS Series Active Subwoofers feature powerful DSP, which allow you to adjust a number of useful parameters.
