Floor-positioned subwoofers take advantage of \u201chalf-space\u201d loading, which increases radiated power by about 3 dB, WITHOUT adding any extra amplifier power. Even better: place the subwoofers on the floor AND push them all the way back against the solid wall behind the screen. That is called \u201cquarter space\u201d loading, and results in about 6 dB greater SPL, without using a larger amplifier. The very low frequencies produced by the subwoofers have no problem going right through any draping or masking below the screen.<\/p>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Take advantage of free acoustical power: always place subwoofers on the floor behind the screen \u2013 NOT on a platform with the screen loudspeakers.
