JBL CBT 70J-1 & JBL CBT 70JE-1 Line Array Speakers

I have 2 pairs of each JBL CBT 70 main and extension. 500 watts Line Array Column Speakers Black 500w Line Array Column The CBT 70J-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers. The CBT 70JE‑1 is a passive extension module designed to attach to the CBT 70J‑1 column loudspeaker, extending bass response and enhancing SPL. Housed in a weather-resistant fiberglass-reinforced ABS enclosure, it includes four 130 mm (5″) low-frequency drivers with neodymium magnets and a built-in crossover. It handles up to 500 W RMS and extends downward frequency response to 45 Hz (–10 dB). Features * Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent. * Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers,
arranged coaxially. * Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. * Vertical pattern coverage switchable between 45° for medium-throw coverage and 25° for
long-throw applications. * Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode. * Dynamic SonicGuard™ overload protection of HF devices * Swivel (pan) / tilt wall bracket included.
