Tiltback inline skate wheels in the rear, feet in the front and a top corner handle. If the cab is too low, add a pull out handle. Or use a folding hand cart.
lay it on its side - the side without any casters.
so it gets mechanical coupling to the floor, which can sometimes (but not always) increase the perceived low end. Mechanical coupling can also cause heck with subsonics and other very undesirable low freq magnification.
I've been trying to get someone to explain why mechanical coupling through casters is different than mechanical coupling through feet. (Or in the case of turning the box on its side, through corner protectors.)
You won't, because there is no such acoustic outout from mechanically connecting the cab to the floor.
How does it ruin the cabinet?
“Factory installed” is just people, I’m a people and I know how to install a caster-- it's not rocket science.
but I would probably use a better one than they would.
No insult...but I have seen alot of added casters that can detract from resale...unless they were originally part of the cab.
I just think it better to keep it original and add removable things that don't alter the cab.....especially with expensive cabs.
and you still have stacking options

I disagree with the first part. Get the casters, mount with #10 x 1" metal screws, and they're removable with minor marks - but anyone who buys a cab that weighs 50+ pounds is much more likely to appreciate having them there. It certainly does NOT "ruin" a cab! Just don't butcher it up.
Here's an example of mounting this way:
Strapping things on dollies (and furniture dollies are common) gets really old really fast, and results in more dollies and straps to deal with at every step.

I use a playground surface tile for vibration isolation under my cabinet when playing on a hollow stage. It solves the boomy mud problem. It is also heavy, as is my cabinet. Wheels are good. How you choose to attach or not attach them is personal preference. My preference is really big cabinets that work like a hand truck. I think those are the easiest to move, weight or no weight. I also have a van, so my quirky personal preferences aren't universal.
well...I will not buy a cab that has holes punctured in it by someone screwing in casters.
You don't know if they made several holes in an attempt to get it right and if it does not have the anchors for removable casters, I wonder also about the stress the cabinet wood has been put under as it goes over pot holes and rough terrain....broken casters??ripped out screws.
If it breaks on your permanently attached dolly ....The cabinet is not damaged and remains in as new condition
just a rule for me that would prevent me from buying a cabinet some possible clown attached casters to

No casters on my cabs, I want my cab to stay put.
The woofer(s) will exert some force on the cabinet itself and with very low frequencies the cab will rock back 'n forth when put on casters. This will have impact on the tightness of the bass-sound coming from your cab. A cabinet that stays still has a more detailed sound, this is why an impulse-compensated design will sound better then a regular one.

I`ve upgraded all my casters to have locks to address that issue.
I dug this tread up because of an experience I recently had. I have two 4x10 cabs. Both on casters. I had just got the older one back from having total speaker replacement. Since it was to be my top cab I decided to remove the casters so it could sit upright instead of on its side. I also decided to remove the ones on the bottom cab as it tips forward to easily when moving it. It's an Ampeg PF-410 and lighter than the GK cab that I sit on top so no big deal. Now I had a gig outside a few nights ago and decided to use the GK. We have played there before and I knew what to expect from the stage and area. The GK had always been equipped with its casters in the past but not this time. Wow! What a difference not having the casters seemed to make. I actually had to turn down volume, bass and low mids. I'm sure the new speakers in that cab helped(they are an upgrade) but the head is the same. I guess cabs do sound better without them. Good thing I have lots of help around to move them.

C'mon folks, let's think about acoustic coupling and use some science to understand why casters do not affect acoustic (boundary) coupling to any meaningful amount.
The acoustic coupling or boundary effects occurs where the spacing off of the boundary is a significant distance compared with the wavelengths being considered. Since the drivers are usually several inches from the bottom edge of the cabinet, adding 3" casters does nothing relative to <500Hz (didn't do the math, engineering guess) and for higher frequencies (not what is being claimed), it's not am constructive coupling but constructive/destructive interference and adding 3" to the path just shifts the frequency pattern slightly.

Regarding replacing the speakers and claiming removing casters was responsible for the improvement, put the casters back on and try again. You will see how out of context your association of cause and effect is.
Joel406 you specifically mentioned that the speakers were upgrades. If they have even a small amount of sensitivity more than the original ones, you could still be looking at +3db net on the cab- there's 4 of them!
