A backcan is a rear enclosure that fits behind a ceiling speaker driver, providing acoustic isolation, fire-rating support, and plenum-space containment. This pack of six units allows installers to stock enough hardware for a multi-speaker job without ordering individual pieces. The CSS-BB4X6 is a direct accessory from JBL PROFESSIONAL, ensuring dimensional fit with the corresponding CSS8004 speaker basket without modification. Commercial AV and low-voltage contractors are the primary installers for this type of product.\u003c\/p\u003e\n\u003cp\u003eBackcans like the CSS-BB4X6 are used in commercial and light commercial ceiling speaker installations where code, acoustics, or owner specifications require rear enclosures. Typical applications include conference rooms, corridors, retail spaces, and open-office environments where CSS8004 speakers are installed in drop ceilings or drywall. Installing backcans in plenum-rated ceiling spaces is often required by local fire and building codes. This 6-pack format suits contractors running multi-zone distributed audio systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePack of 6 backcans for efficient multi-speaker installations\u003c\/li\u003e\n  \u003cli\u003eDesigned to pair with CSS8004 series ceiling speakers\u003c\/li\u003e\n  \u003cli\u003eProvides rear acoustic isolation for improved sound containment\u003c\/li\u003e\n  \u003cli\u003eSupports plenum-space and fire-code compliance requirements when properly installed\u003c\/li\u003e\n  \u003cli\u003eOEM accessory from JBL PROFESSIONAL ensuring dimensional compatibility with the CSS8004 basket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with JBL PROFESSIONAL CSS8004 series ceiling speakers as stated in the product designation.
