Each of the three full-range StudioLive AI-series loudspeakers has been phase- and time-aligned to form a true 4-way system when paired with an 18sAI sub-woofer, with or without the 100 Hz high-pass filter engaged. For applications where a frequency overlap at 100 Hz is beneficial, you can achieve bigger bass sound without any extra effort. For applications that require a more linear frequency response between the sub-woofer and full-range content, simply engage the high-pass filter on the full-range AI-series loudspeaker. This will also readjust the phase and time-alignment to keep it in phase with the 18sAI sub-woofer, enabling you to create the best four way system for your application.
The StudioLive 18sAI sub-woofer also provides three on board alignment delay presets so you can keep your four-way StudioLive AI PA system in alignment even if your sub-woofer is one or two meters away from the full-range system. When SL Room Control becomes available in Spring 2014, you will be able to customize the alignment delay settings further.
