Getting my cabinet off the floor?

The lead singer in our band wants me to put casters on my Hartke 2x15. I don't think it's necessary, because it's not that heavy... and I'm lazy. He's saying it would also be beneficial to have the speaker isolated from the floor. I've heard that before, but I figured I would ask y'all as well:

Does isolation really matter that much... and would casters even be the equivalent of good isolation - if such a thing really exists?

If you're lazy you need casters.;)

I have had both- 2x15 cabs with/without casters and have'nt really noticed a difference between the two. What does seem to make the difference is the type of stage you play on, how high it is, what it is made out, of etc.

...would casters have an effect on acoustically decoupling the cabinet from the floor/surface? later, ron

No. Acoustically decoupling requires that the cab be lifted at least 1/4 wavelength. The three inches that you might get with casters is 1/4 wavelength at 1130 Hz. Boom is usually centered in the vicinity of 100 Hz, where 1/4 wavelength is 34 inches.

I use a piano dolly for my gear, I prefer to have the cabinet on the floor, call me superstitious, I don't like casters on a cabinet because eventually the bass frequencies will rattle those poor little wheels apart. you could put larger more industrial casters on your cabinet, but that increases the size of the cabinet (will it still fit in your car?) and it also adds weight to the cabinet (you will have to lift it in and out of your car and casters don't work on stairs.)

I think he's saying that he's lazy and even HE doesn't think he needs casters...that was an argument against, not for, casters.

That said, they're right. You'd need to get a good three feet before you loose that 'boom'. But if your [even lazier] singer is that concerned about moving your rig around I'd second MNAirHead and get a 2nd plate/cart. It gives you more options.

No, no and yes. If you lift the cab high enough it can help reduce boom. But it takes a 2 to 4 foot lift to accomplish that.

I understand this in theory, but I've found that by putting my 410 on 3" casters it greatly reduced the stage boom. Take the casters off and it was boomy and the notes were hard to distinguish. Back on and it was focused and even; I actually had to turn the bass up a notch (using MB F1 and Berg AE410, FYI). Just my experience.
