Wheels for floor standing speakers

I have Tekton Moab’s that I need to move a lot

I’m still trying to wrap my head around why speakers need to be moved "a lot". Especially those that weigh 135 lbs
As Jason said, there are lots of choices but small wheels may not be a whole lot easier than the gliders you already have. And larger ones will lift the speaker above its optimum placement. Whatever you get, the speakers need to be pushed from the bottom rather than upper part of the speaker. That may be all wifey needs to do to move them on the gliders. She is probably pushing from the upper portion.
If nothing else, get a couple hand carts and paint them to match the décor and then place them in back of the speakers in the ready position

Better be careful. 

Large caster wheels that are through bolted through the cabinets would work best i have a lot of large speakers and the biggest ones require that you have and use these types of accesories.

Just make sure two of them have brakes or the speakers will move. You have to be careful with the screws. MDF will strip easily. Predrill the holes and use self tapping screws. Fill the holes with thin cyanoacrylate glue like Satellite City and run the screws in with only 4 nm torque. This is permanent but at least the casters will not loosen. MDF can always be repaired but matching the finish will be tough. You will decrease the resale value in any event. 

Awesome guys!! Thanks. Yea, they’re actually mainly gonna be my wife’s speakers now. I just got a killer deal on a pair of Sopra 3s. Was gonna sell the Moab’s, which I really like btw, and was sad to see them go, but then my wife mentioned that she’d love to have a HiFi setup in her piano studio. So…. I moved the Moab’s to her studio, ordered an NAD M33 all in one for her. She should be very happy. She has lots of rehearsals so needs to move things around a lot in her studio. I’m aware it’s not the best sonic solution to put wheels on speakers but it is what it is.  Hoping to get to a hardware store this week for a look at wheels. Thanks again for all the help everyone!
