The JBL CBT 70J-1 passive speaker uses JBL's breakthrough Constant Beamwidth Technology to produce a column speaker with incredibly balanced projection across a large area. Passive column speakers normally create inconsistencies in sound when you move about the room, but not the CBT 70J-1! JBL's patent-pending design uses an array of four 5" LF drivers and sixteen 1" HF drivers, and the result is consistent, natural sound coverage - both horizontally and vertically. You can even tailor the vertical dispersion to optimize the sound to any room! Perfect for large rooms like churches, school auditoriums, and theaters, the CBT 70J-1 is easy to install as well as easy to optimize for your room. Call Sweetwater today to find out how you can integrate the JBL CBT 70J-1 passive speakers into your live sound system!
JBL CBT 70J-1Passive Speaker at a Glance:
Innovative design for superior sound coverageThe JBL CBT 70J-1 handles up to 500 watts of power to drive an array of four 5" LF drivers and sixteen 1" HF drivers. 10 years of research have created a column speaker that uses analog delay beam-forming and amplitude tapering to make sure directivity is even across the CBT 70J-1's extended 60Hz-20kHz frequency range. The result is even, balanced sound without frequency lobing inconsistencies as you move around the coverage area. Best of all, you can switch between 45-degree vertical dispersion (for medium-throw coverage in smaller rooms) and 25-degree vertical dispersion (for long-throw coverage in larger rooms).
Perfect for performance and speechAny place you need clear, balanced sound that covers a large area well, the JBL CBT 70J-1 will deliver. Switchable voicings let the CBT 70J-1 use a flat frequency response for music playback, as well as a speech mode with a midrange presence boost. It's ideal for school auditoriums and churches, allowing your message to be heard clearly throughout the room. Anywhere you have a large room that requires lots of coverage without the compromise of dead spots or frequency lobing, the CBT 70J-1 is ready to perform.
Easy to installJBL's CBT 70J-1 column speakers come with a swiveling wall bracket, and also have 10 threaded insert points on the rear of the fiberglass reinforced ABS cabinet. Contractors love how easy it is to install the CBT series, and it's easy to position them for the maximum coverage in your room.
