Members Nasty Posted September 1, 2005 Members Share Posted September 1, 2005 does it matter which way your cab lays when you transport it? is it better to have the speakers facing up so they vibrate in the same direction they are used to? or is better to have them facing perpendicular so that they might not age prematurely?

Members Deville Posted September 1, 2005 Members Share Posted September 1, 2005 Frankly, I don't think it matters. We punish our speakers under normal operating conditions way more than any road bumpiness could, and most of the time they take it with ease.I certainly don't worry about it. Whatever fits the best!

Members The Insomniac Posted September 1, 2005 Members Share Posted September 1, 2005 I was told once not to transport the cab with the magnate facing down. A large bump could send it to the bottom of the cab. I have no idea if it's true or not but seemed to make sense at the time. Link to comment Share on other sites More sharing options...

On speakers that carry a lot of travel in the basket and low piston resistance, a bum can ruin the former that holds the winds - thusly killing the driver once power is applied. It is best to have the speaker facing forward with the driver travel parallel to the ground. Link to comment Share on other sites More sharing options...

It is best to have the speaker facing forward with the driver travel parallel to the ground. That's indicative of one of two things: A very very large bump or a poorly designed driver. This is an extenuating circumstance, and equivalent to the scattered magnet shift from transporting them facing forward with the driver travel parallel to the ground. I've transported literally thousands of cabinets, thousands of miles, in everything from small cars to semis, in every possible arrangement, and I've only seen a few drivers damaged in transit. Generally, it doesn't matter. Link to comment Share on other sites More sharing options...

I take the care nowadays. Never had the same issue with guitar or PA speakers, but anything with "loose travel" I take special care. Link to comment Share on other sites More sharing options...
Members SA Rios Posted September 1, 2005 Members Share Posted September 1, 2005 hmmm. I've never had a problem with any of my cabs both eden or ampeg. The only way they fit in my trunk is lying flat and I've been transporting cabs like that for 10 years, bumpy rd's, flat, you name it. I think it might be a fluke thing that happens to flawed speakers. Link to comment Share on other sites More sharing options...
Members bnyswonger Posted September 2, 2005 Members Share Posted September 2, 2005 The construction of my JBL K145s is so beefy, I can't imagine them shifting from any sort of bump...they don't seem to give a hoot about orientation either ....unless of course the van got totalled.... They might survive that too, but I don't plan on researching it... Link to comment Share on other sites More sharing options...

That's interesting (not being sarcastic here). I've been dealing with speaker manufacturers for 15 years and haven't encountered this. I will say that in my opinion, any speaker compliant enough that transportation can damage the former, is poorly designed. Or, perhaps "not optimally designed" would be a better way to say it. You can do something to increase the resistance of the cone to travel though. Use a shorting plug. If the terminals are shorted, when a bump makes the cone move, the coil moving in the magentic field will produce a current that will tend to oppose the movement.

That's a great idea. I'll do that in the future Link to comment Share on other sites More sharing options...
