July is typically a slow month for online endeavors. All the college kids are out doing their summer jobs and us working schlubs are off running festival stages. But for those still tuning in somewhat regularly I've at least got a few links.
ProSoundWeb had a decent article this week about the directivity of speaker arrays. It covers both line arrays and sub woofer arrays and talks about the different effects of physical aiming and aiming with delay have. It's by no means exhaustive but it's a good primer for those who have no idea on the topic and might even clear a few things up for people who already have some understanding.
