We are speculating that the cause of the punch throughs are due to the installation that we use for testing. Based on the instructions that LI provides for the firmware update, we feel that they want the heads positioned in that fashion to minimize interference between the heads. It is possible if the heads are installed so they are also recessed and isolated from each other it may result in improved performance.

Sounds like crosstalk issue on the LIs if they are chanting them out a bit. We've seen this before, but why would a firmware update cause the new or additional cross talking?
