The HALO Arena has been revealed by EM Acoustics, with the new product taking the company for the first time into the arena sound reinforcement market. Built using the same core design as the much smaller HALO-C, the Halo Arena takes overall SPL capability to a level EM Acoustics believes is suitable for much larger applications, both fixed installation and touring.
While HALO Arena delivers the same performance and coverage as HALO-C, the technology used to achieve it is different, due to the much higher SPLs required from the Arena. Rather than an AMT plane-wave guide, EM Acoustics has used compression drivers with a specially developed patent-pending emulation manifold which combines the energy of four 3.4in diaphragm, 1.4in exit compression drivers into a plane-wave array.
A single HALO Arena cabinet is said to exhibit a flat, free-field frequency response from 48Hz to 19kHz (+/-3dB) and a phase response which is +/- 20º between 150Hz and 18kHz. Due to the loading technique applied to the low frequency drivers combined with the high frequency waveguide, the dispersion pattern control is maintained down to 250Hz.
The bottom end is served by a pair of high power 3.5in voice coil, 12in low frequency transducers.
