You guys are a humourous (humorous) bunch of fellas and a pleasure to hang out with every day.
Just as a matter of interest, at a gig venue (or even at home) when loading or unloading at any distance from the band trailer, truck, car, wagon etc etc over a rough uneven surface like a bitumen (blacktop) car park, paved area or similar, I carry my combo and also the ext. speaker cab
instead of rolling it on their wheels. My Fender Rumble rig (500C and 115 cab) is lightweight enough to carry using the handles either on top or sides of the cabs. Having said that about my lightweight rig, when I used my heavy 122lb Peavey cab between mid 80's to current times, I still get a second person to help me carry my gut busting 1820 cab instead of rolling it on wheels. To my way of thinking the speakers have a hard enough job to do as a bass players rig, without the stress on the cones caused by possible unnecessary vibrations that could be avoided.
I have always worried that rolling over those types of rough surfaces bounces the speaker/driver cone around too much in an unnatural direction, so to avoid any cone displacement or damage issues I carry instead of roll. I only roll inside a smooth surfaced venue...eg. carpet. concrete, wooden flooring etc.
I have done this since the 60's during my entire musical career. I still don't know for sure if this protective method I have employed is of any use in preventing any physical damage to speaker cones or not, or am I just too over careful. I will say that in all my 50+ years of doing it this way I have never damaged or even blown a speaker/driver so maybe the practice has paid off. What is everyone's thoughts on the matter. Am I too paranoid and over-protective of the amps and cabs speakers, or is it a good practice to get into?
EDIT: Of course none of the above text relates to the use of pneumatic tyres (tires) on handcarts, sack trucks, trolleys, dollys, etc and the like. I'm only referring to the removable wheels on the actual cabs, like the removable Gibson and Fender type ones like on the pic of my 115 cab below.
