Compact systems composed of 8in. or smaller low-/mid-frequency drivers.
The D.A.S. Audio Aero 8A is a self-powered system with a 2-channel Class D amplifier (250W LF and 100W HF). The loudspeaker incorporates one 8in. low-frequency driver and a compression high-frequency driver attached to a waveguide horn assembly. The frequency response is 95Hz to 20kHz, and peak SPL at 1 meter is 128dB. Horizontal coverage is 90 degrees. The unit weighs 39.6lbs. and measures 9.6"x20.7"x14" (HxWxD). A two-position HF EQ compensation switch that adjusts the high-frequency response for arrays of four, eight, or more units is located on the rear panel.
d&b audiotechnik's T10 loudspeaker is a passive two-way loudspeaker with two 6.5in. drivers in a dipolar arrangement and a 1.4in. HF compression driver with a passive crossover network. The T10 can be configured as either a line-array or a point-source loudspeaker by rotating the HF horn. The HF driver is fitted to a waveguide horn with an acoustic lens placed in front of the horn providing horizontal coverage to 105 degrees. Its frequency response is 68Hz to 18kHz, and its maximum SPL is 132dB with the d&b D12 amplifier. The unit measures 7.72"x18.5"x11.81" (HxWxD) and weighs 24lbs.
dB Technologies' DVA T4 active line-array module top is equipped with a constant directivity horn for the high and mid section (two 1in. compression drivers and one 6.5in. midrange driver). One 8in. is used for LF with an overall frequency response of 80Hz to 19kHz and a maximum SPL of 123 B. The cabinet weighs 29.1lbs., and the DVA T4 features an integrated digital Class T amplifier.
The Duran Audio AXYS Target U-16 has a frequency response of 160Hz to 20kHz and a coverage angle of 90 degrees. The maximum SPL is 123dB at 1 meter. The driver complement is two 6.5in. direct radiating low/mid drivers and one 1in. horn-loaded compression driver. The self-powered system features a Class AB amplifier, and a single element weighs in at 55lbs.
The NTL720 from EAW is a self-powered, three-way line-array loudspeaker. The driver complement includes two 6in. LF, two 6in. LMF, and six 1in. HF. One large MF/HF horn fills the entire face of the enclosure. The side-mounted LF drivers are frequency-shaded, providing proper integration with the front-firing LF/MF drivers while supplying additional LF output and extended horizontal pattern control. Self-powering is supplied by three 500W Class D amplifier modules. The system features EAW's Gunness Focusing. The peak SPL is 133dB with 110-degree horizontal coverage, and the unit weighs approximately 47lbs.
