Reviving an old thread because I'm reviving a beat up old SVT 8X10 cab, but if I have to move this thing there will be no reviving this even older more beat-up bass player.
I replaced all the drivers with lighter Eminence that have neo magnets. The magnet structures and stamped steel frames are still pretty heavy. Probably saves about 30+ pounds? Still a bit more than 100 when done, I conjecture. It's still significant as the weight of each adds up fast with 8 of them.
This one has no wheels or skid plates at the moment. I hate the idea of using skateboard trucks.
So features to consider, from other threads and various places:
1) More than 2 wheels along the back 'angled' edge. But on uneven surfaces, unless they have soft rubber wheels some wheels may be off the ground and rattle. I've had this problem before, and cut some sponges into wedges to jam into wheels if they rattle. Pain in the butt. But with only 2 small narrow wheels you can't really move the bottom across grass, dirt, etc. and the skid ralis get a lot more beat up on stairs. Bigger wheels also mean that the rear has a wider track and won't ever fall over backward.
2) Much larger rubber-tired wheels along the back 'angled' edge, but not pneumatic (pain in the butt).
3) Smaller caster wheels at the front edge for moving cabinet when it is standing up and not tilted back. Will this allow it to roll off stage too easily? Will I need retractable feet or locking casters (locking against caster rotation and/or wheel rotation?)? Will I need to carry anti-roll "cookies" or some kind of wheel chocks?
4) It's possible to have more than 2 front wheels, but that makes it more vulnerable to stopping when it hits any small pebble on a floor, and possibly even tip over.
5) With some smaller wheels at the front as in #3, it's also possible to put the same small casters in the back, which would allow you to roll it sideways, for example. But that means the big main rear wheels are off the ground when in-use, and could rattle unless chosen very carefully.
6) Some tilt-back-to-move cabinets that move like a hand-truck now come with a lightweight alujminum diamond-tread kick plate for you to push with your foot against to tilt it back. Something like a block of wood mounted on the back of the cabinet would make it even easier to tilt back, but would also catch on stairs. If big wheels stick out the back, then a low block on the back could be mounted on the angle board and be protected within the profile of the wheels....and covered with aluminujm diamond-plate.
7) Multiple aluminum slider rails on the back are a possibility. Slider rails aren't really much good on stairs, especially not concrete stairs, but they do help load into an SUV etc. The more there are the less load on each, and the lighter the better.
8) There are real stair-sliders which are small rollers between plates, with an short automotive-type fan belt riding on the rollers. These things work great, and are usually found bolted onto an appliance-dolly hand truck. But they rattle A LOT and would need to be removable.
9) If each edge of the back of the cabinet had about 4 staggered wheels that overlap horizontally, then it could go down stairs with only a very slight "bump bump bump" which might actually make it a little easier to control. But again I would have to choose carefully so they don't rattle when off the ground.
10) If I don't have front casters too, but have large rear wheels, then the rubber feet in the front would need to be much larger.
11) Folding cabinet handles mounted on the bottom near the front, as someone else did in this thread, are an excellent idea, unless they rattle when gravity is pulling them down a bit while playing. If the wheels are really big you could even mount another towel-bar type handle between the front feet. They sell handicapped bars for the bathroom in many sizes, and they are really strong. A rigid front bar would be even better than folding ones, with greater control over tipping and torsion, no chance of pinching fingers, and also protects the front edge against damage.
12) Of course if I bolt too much of this junk on it will always rattle and weigh as much as it did with the original drivers. And with a bunch of wheels or big wheels it might not fit into a standard shipping AT road case. Vinyl covers area another problem if there are a lot of metal slider rails, as the rails need to protrude thru the vinyl if they are going to do anything.
13) There is a lot to be said for making a wood front cover that latches on with twist-type cam latches. And aluminum edges and beefy cast aluminum metal corners. It doesn't end up looking like a classic old SVT bottom, but it doesn't end up looking like this beat-up piece of junk every few years either.
Of course if I add all kinds of wheels and bars and sliders and front covers and vinyl covers, it will weigh more than it did originally with the heavy stock speakers.
Any and all opinions and advice would be much appreciated.
