Fact or fiction? Transporting a cab lying down is bad for the speaker cones??

#81
I've hauled speakers around since 1965, and I have never seen one damaged by transportion regardless to the orientation. Your magnet is not going to pull on the cone, because there is no mechanical connection between the cone and the magnet, except through the frame. If your magnet is heavy enough to warp the frame, you either have very cheap speakers or your magnet is too heavy.

It's probably as relevant as my spelling of significant.

I once kept a Sunn 2x15 in the (covered) bed of my pickup for a few weeks. At some point the bar holding it in place broke free, and when I came to a sudden stop, the cab slide 8' and smacked the front of the bed - sending the trunk lunging forward. When I hit the gas, the opposite action occurred - sending the cab hurdling towards the tailgate "whomp!". After a couple weeks of this, I took the cab out - sure enough one of the speakers was no longer working.

Does this have anything to do with cab orientation? No - but does show the importance of securing your load. If there's a chance the cab can fall over in transit, pack it differently. Face up, face down... I dunno - just make sure it's stable. And when transporting gear, drive carefully!

This is probably the more important aspect of this discussion. I read some statistics a while back on injuries and fatalities due to unsecured items flying around a vehicle in an accident. Amps, speaker cabs, dressers, luggage, even people without seat belts can become lethal flying projectiles in a collision.

Gravity has no effect on the amount of magnetic force the speaker pulls on the cone. The wieght of the magnet is mounted to the speaker structure, not the cone. However, driving like a bat out of hell with an unsecured cab will effect the cones. The magnet will pull on the cones (without power input) the same no matter the orientation of the speaker. Bouncing around will put stress on the cones and the wiring connections used to power the magnet. My 0.02, take it as you will.

Lest my comment be misinterpreted, my intent in the diagram was to point out that the force of the bump may directly impact the heavy magnets. They could conceivably be yanked off the frames if they were massive and poorly attached.
