Amazingly Balanced Sound for Any Room or Theater

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!

Innovative design for superior sound coverage

The 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 speech

Any 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 install

JBL'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. Call Sweetwater to find out more about how to integrate the CBT 70J-1 into your sound system!

Perfect DJ Speaker ??

I know these are "installation" speakers. I replaced My BOSE LI's with these and a JBL powered sub. So far, real good. Easier to raise above the crowd and tilt down. Killer tone. Very smooth response. Easy to put on a speaker stand. I'm still figuring out optimum crossover points and EQ settings. Not for everybody I guess ... but I give them 5 stars.

Great for the living room

it just isn't suited to a large room for sound reinforcement. 5" speakers and 1" tweeters will only perform as you would expect - in a small space. A simple 15" speaker and horn will outperform these pricey beasts in a church or auditorium with ease.

Sweetwater Advice

Robby Resnick

Some things function as both art and object. This is absolutely one of them. The JBL CBT's provide line array coverage and clarity for a fraction of the cost of other systems. They sound amazing on their own for spoken word or - coupled with a CBT 50 or 100 - can project music throughout a large space without losing clarity. It amazes me how they have controlled and focused the energy these boxes put out. (And when installed properly, they are as pretty to look at as they are to listen to!)
