Electro-Voice XLD281

Electro-Voice XLD281

The XLD281 from Electro-Voice is a three-way design using Coverage Control Technology (CCT) to control horizontal coverage to 250Hz. The XLD281 uses an 8in. neodymium, low-frequency transducer; an 8in. neodymium, LF/MB transducer; and two 2in. neodymium, voice-coil compression drivers combining through two Hydra plane wave generators into a 120 degree-by-10 degree waveguide. The XLD281 can be used in triamp mode, or in biamp mode using a sophisticated internal passive network. The unit has a frequency response of 60Hz to 20kHz, the maximum SPL is 141dB, and the unit weighs 48.06lbs.

JBL Professional VT4886

JBL Professional's VT4886 enclosure houses two 6.5in. low-frequency transducers, four 2.5in. midrange components, and two 1in. high-frequency compression drivers. A proprietary waveguide integrates MF and HF section output. The frequency range (-10dB) is 65Hz to 20kHz with 110 degrees of horizontal coverage, the peak SPL is 136dB, and the cabinet weighs 34lbs. Application flexibility was a key design criterion, and in addition to a number of rigging configurations, this system can be pole-mounted.

L-Acoustics KARAi

L-Acoustics KARAi

The KARAi modular line source for permanent installation from L-Acoustics has an operating frequency bandwidth from 55Hz to 20kHz. KARAi features a two-way, biamplified design and is equipped with two 8in. neodymium LF speakers in a bass-reflex tuned enclosure. The HF section features a 3in. neodymium diaphragm driver coupled to a DOSC waveguide. The system features a horizontal coverage of 110 degrees. The enclosure weight is 57.2lbs., and the maximum SPL is 139dB.

Martin Audio's W8LMI three-way line-array element comprises Hybrid dual 8in. LF and MF configuration and twin 1in. HF horns. Horizontal coverage is 100 degrees by 120 degrees down to 700Hz. The loudspeaker is configurable for either passive or biamp operation. The maximum SPL is 131dB, and the unit weighs 64lbs.

The In.line series from McCauley Sound is available in three full range modules. The N120 features a 120-degree horizontal coverage pattern, the N90 90 degrees, and the N60 60 degrees. The models in the In.line series use a three-way biamplified complement of twin 8.8in. cone drivers and a 1in. exit high-frequency compression driver. The frequency response is 60Hz to 18kHz with a peak SPL of 132dB.
