The ZSOUND LC18P-III is a high-performance <strong>Active 18-inch Bass Enclosure<\/strong> designed to provide that physical &#8220;thump&#8221; for clubs, theaters, and touring shows. For those new to professional audio, this unit acts as the strong foundation of your entire sound system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The &#8220;Active&#8221; Advantage: Built-in Amplification and Control<\/h3>\n\n\n\n<p>What makes this an &#8220;Active&#8221; system is that the power engine\u2014the amplifier\u2014is built directly into the wooden box. This means you don&#8217;t need a separate, heavy rack of external amplifiers to make it work.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Built-in Amplifier Module:<\/strong> The LC18P-III features a dual-channel 2000W amplifier module. In simple terms, this provides more than enough &#8220;muscle&#8221; to drive the speaker to its maximum potential without getting tired.<\/li>\n\n\n\n<li><strong>Integrated DSP:<\/strong> This <strong>Active 18-inch Bass Enclosure<\/strong> includes a &#8220;brain&#8221; called a DSP (Digital Signal Processing).\n<ul class=\"wp-block-list\">\n<li><em>Explanation:<\/em> DSP is a specialized computer inside the speaker that automatically cleans up the audio signal, prevents the speaker from blowing out, and ensures the sound is perfectly balanced.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Massive Performance: Moving Air with an 18-inch Driver<\/h3>\n\n\n\n<p>The heart of this <strong>Active 18-inch Bass Enclosure<\/strong> is its massive 18-inch &#8220;driver&#8221; (the actual circular speaker part that moves back and forth).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High SPL Capabilities:<\/strong> The LC18P-III can reach a Maximum SPL of 136dB.\n<ul class=\"wp-block-list\">\n<li><em>Explanation:<\/em> SPL stands for Sound Pressure Level. It is a measurement of how loud a speaker can go. At 136dB, this subwoofer is powerful enough to be heard\u2014and felt\u2014clearly even in large, noisy crowds.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Deep Frequency Response:<\/strong> This unit can play sounds as low as 28Hz.\n<ul class=\"wp-block-list\">\n<li><em>Explanation:<\/em> Frequency response measures the &#8220;pitch&#8221; range. 28Hz is a very low, deep bass note that is often felt more than it is heard, giving your music a rich, professional feel.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>100mm Voice Coil:<\/strong> The driver uses a 100mm voice coil.\n<ul class=\"wp-block-list\">\n<li><em>Explanation:<\/em> The voice coil is the coil of wire that turns electricity into movement. A larger coil, like this one, can handle more heat and power, making the speaker last longer during long events.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Touring-Ready Design: Mobility and Integration<\/h3>\n\n\n\n<p>ZSOUND designed this <strong>Active 18-inch Bass Enclosure<\/strong> to be as easy to move as it is to listen to. Weighing 70kg, it is a sturdy piece of professional gear, but it comes with clever features for transport.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Wheels and Bumper:<\/strong> The bottom of the cabinet (the protective wooden box) is equipped with wheels and a &#8220;bumper&#8221;.\n<ul class=\"wp-block-list\">\n<li><em>Explanation:<\/em> A bumper is a reinforced frame that protects the speaker from bumps and scratches while you are rolling it in and out of a venue.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Seamless Integration:<\/strong> The LC18P-III is the perfect partner for the ZSOUND LC10 line array. The top of this <strong>Active 18-inch Bass Enclosure<\/strong> is designed with a specific &#8220;surface&#8221; that has space for two LC10 speakers. This allows you to stack your system safely and efficiently, saving space in your truck and on the stage.<\/li>\n<\/ul>\n\n\n\n<p>Whether you are setting up a permanent system in a church or taking your show on the road, the LC18P-III provides the deep, reliable bass you need in one convenient, powerful package.<\/p>\n<\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Applications Feature ZSOUND LC18P-III: Experience Deep Power with the Active 18-inch Bass Enclosure Technical Specification Parameter Name Parameter Value FREQUENCY RESPONSE 28 Hz-250 Hz (\u00b13dB) NOMINAL COVERAGE Omnidirectional POWER RATING (AES) 1200W MAXIMUM SPL 136 dB SPL peak DRIVERS 1&#215;18&#8243; woofer (100mm voice coil) POWER REQUIREMENT 200-240V-50-60Hz AMPLIFIER MODULE Dual channel 2000W (4\u03a9) THD+N 0.82% [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":362,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[5,10],"tags":[],"class_list":["post-361","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pro_audio","category-pin"],"jetpack_featured_media_url":"https:\/\/zsoundpro.com\/wp-content\/uploads\/2026\/01\/LC18P-III-\u4e3b\u56fe.jpg","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/posts\/361","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/comments?post=361"}],"version-history":[{"count":3,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/posts\/361\/revisions"}],"predecessor-version":[{"id":636,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/posts\/361\/revisions\/636"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/media\/362"}],"wp:attachment":[{"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/media?parent=361"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/categories?post=361"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/zsoundpro.com\/fr\/wp-json\/wp\/v2\/tags?post=361"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
