Moving an Amp or Cabinet - Face-Up or Face-Down

Considering how long I've been playing bass and the number of times I've moved my rig, you think I'd be 100% certain on this. But since I've been using a 1970s B-15N at recent gigs, I'm pondering this question:

When you move an amp or a speaker cabinet, and it has to be transporting laying down, should the speakers be facing up or facing down? Or does it matter?

I'm aware of the perils of face-up and something shifting onto the amp, so my question concerns only possible damage due to the speakers facing one way or the other.

BTW I do wrap a nylon strap around the amp to keep the latched-down head from moving during transport.

I've heard drivers can be hurt by being transported lying down, but I don't believe it. Even in the unlikely event that the cones receive a sufficient jolt to make them over travel, there is no force behind it but the inertia of the paper cone. I can't see them being that fragile.

I was always told to transport cabs with speakers facing upwards.

Something to do with the weight on the cone if transported face down which will in time weaken or possibly damage the speaker.

Like lowfreq, If I had to transport a cab lying down I would put it face down so there was no chance the driver(s) could be damaged by any sharp objects fallinig thru the grille.

Optimal solution of course always is always to transport the cabinet in as close to its normal orientation as possible (upright, top side up), but if that's not possible I'd go face down.

I am no professional either but I have always been told to have it lie down with the speakers faces up. i have no reasoning behind it but thats just what ive been told.
but like everyone else has been saying, i dont think the speakers are fragile enough for it to really matter

it depends on if the speakers are front or rear loaded.

front loaded get hauled speakers up so the weight is sitting on the wood not pulling against the screws.

i think i read this in my eden manual.

Unreal.

I've never even thought about it. And I've been doing this a long long time.

It matters more how your speakers are attached, and what they are attached to. If your speakers are attached by wood screws into wood, or if your speakers are attached to a "particle board" or MDF baffle, this is the correct answer.

Otherwise it's personal preference. I prefer to protect the grill from punctures or scratching as that is what is seen most by an audience, and therefore keeps it looking better... My speakers are also front loaded, and attached to the baffle by machine screws and T-nuts.

if the screws that are holding you speakers in are that fragile for fear of the weight of the speaker pulling them out during transport, you should remount them with T-nuts or threaded inserts.

if my cab has to be lying down when hauling it, i lay it on its face so nothing can fall on the grill.
