The speaker break-in thread got me thinking of something I heard many years ago regarding hauling your gear. The premise of this is as follows: while hauling your speakers only set the cabs with the speaker oriented in its vertical position. Not with the cone facing up (on its back) or down (on its face). The cab could be on its side so long as the cone was in a vertical orientation. The theory was that the speaker wouldn't over-travel its range while driving down the road. Anyone else ever heard this? Do you only stow your cabs in a specific orientation when hauling them?
