Mounting Speakers On A Furniture Dolly For Mobility

Yes  use spikes as this will decouple to much and you will loose sound quality and bass detail.

I have alway thought about designing a system for this application. It would be an adjustable platform to fit the speaker and have a foot lever to engage the wheels and then when in place the wheels retract and the floor spikes would support the speakers. You could even design them as spring loaded dampening system once in place. always figured we have people paying 100 k for a piece of wire they would surly pay a few thousand for speaker carts.

Hello Mitch 41. I put casters on my 15" subwoofer cabinets and Shahanian puts casters on their Obelisk models ($7000/pr ish). Just be sure the casters don't rattle when shaken vigorously. If you can find some with softish wheels, you may solve two problems at once. Happy listening.

I'm 73, been messing about for quite a few years. Surprisingly only 3 different spaces including parlor floor of a brownstone with 13 ft ceilings when in college.

My JSE Infinite Slope Model 2's came from the factory with 4 wheels. One wheel might not touch the floor, had to squish in a shim every attempted location, every time moved out of the way ...

After a while, removed wheels, put spikes. no difference except inconvenience and inability to adjust toe-in, push out of the way ....

Gave spikes to my friend, put 3 wheels and rear corner blocks.

Gave JSE's to my son, put 3 similar dual wheel casters on current speakers as noted above.

My friend still has the spikes. You must sit in the middle for imaging. I just encouraged him toe them in more. He did,  better now when off center, but not really.

Mine: X pattern Toe-In for two listeners with a small table in between. Aim left speaker directly at right chair. Right speaker directly at left chair. Creates a wide image, both get a l/c/r spread because you get direct dispersion from far side and more volume from near side, it 'equals' to a very satisfying result. Back to 'normal' toe-in when my chair is centered.
