Safest Transporting Position?

SurferJoe46 · #1 06-30-2010, 11:22 AM

Is it best to transport a speaker/driver in the normal upright position or on it's back/front?

Thinking about road vibration and shock impact here.

Hi SurferJoe,

Back in March 2010 I asked nearly the same question here on Talkbass, and I think that in the end, the answer was "no one really knows" how to best place an amp when you move it. Here is the thread:

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

But since most amps live their lives in the normal / upright position, this is also probably the best way to transport it.

I've never had any damage to an amp that is directly related to its position when being moved, only by human error when moving it.

I'm going there to read it now. Thanks.

I ran this topic by our engineer over at Eminence as it makes sense to go straight to this source for this type of question.

"For most pro-sound woofers, it really does not matter as the suspension is so tight. On some sub woofers, with really low Fs's, they would need to be on their side and shorted if possible to keep them from slinging around. Bass guitar stuff is pretty much immune from sag, so it can point in about any way you want it to."

For me - any way it'll fit in the van.

I've always wondered about this.

Thanks for the info, R Baer!

Chuck it 'n truck it, that's my motto.

That's what I thought based on expert opinion here, and the Eminence engineer has backed it up. Thank you!

I move my BRX10.4 right side up and my BRX10.2 on it's side, never have had a problem with them not working because of transporting.

You can calculate sag.

Keep the road bumps in mind.

But carrying position will not affect it any more than the underpowering that will happen during the time on the road.

If you're going to guess, I'd say better off speaker facing up. Vibrations and impacts will make the speaker move in and out as it was designed to do. No problem.

Having the speaker setting as you would play it on a gig, the shocks would try to move the stuff sideways compared to the suspension. Not sure if that would cause problems, I doubt it, but that would be the more likely mode of failure as its an unnatural movement/force.
