The main attraction on its stand are additions to the Arion Line Array range, the SL 210 A and the SL 218 SA subwoofer, which are aimed at audio installations, theatres and concert halls. Designed entirely at the Work Pro headquarters in Valencia, Spain, both line array elements were launched last year – this is their first major international trade fair outing since they began shipping in late Autumn 2017. Together, the units form a system suited to use in demanding environments that require power, high-quality audio reproduction and controlled directivity.

The SL 210 A is a two-way, biamplified line array element with the option of remote monitoring and control via Ethernet, a built-in DSP section, and twin 1000W peak Class D Pascal amplifiers (both featuring a built-in universal power supply for seamless use internationally). The low frequencies are handled by two 10-inch Faital Pro LF drivers and a bass reflex enclosure, while a 1.4-inch Beyma compression driver, with a polymer diaphragm, takes care of the high frequencies.

The compression driver feeds the newly developed VI-10 waveguide which perfectly integrates the high frequencies from multiple SL 210 A units, creating a seamless HF response from the complete array. Through careful application of the onboard DSP, tailored passive filtering of one of the LF drivers in the low/mid range and a newly designed dispersion horn, the SL 210 A achieves consistent 120-degree horizontal coverage, with a rock-solid frequency response irrespective of listening position, and is capable of delivering a maximum sound pressure level of 135dB. The frequency response extends from 18kHz down to 100Hz (-10dB).

Lower frequencies can be faithfully reproduced by the new dedicated SL 218 SA subwoofer, which is powered by a 4000W peak Class D Pascal amplifier, and can handle frequencies from 30Hz up to either 120Hz or 140Hz.
