[QUOTE="John Roberts, post: 56394, member: 126"] Re: What exactly does Processing do? While I am not familiar with the vertec's specific processing in general "active speaker processing" picks up to finish where the passive design ends or runs out of options. In an ideal world passive loudspeaker designs could be made almost perfect and we'd just connect amplifiers to them. Back in the bad old days that's all we did because fancy processing did not exist as a viable option. Nowadays modern processing is relatively cheap, and even so cheap in some cases that it is preferable to fix some speakers designs in the processing, but that is not the topic.
