Put casters on them.
As the man said....
Or, put them on a small platform with casters on said platform.
That means you can pull out when you want.
The one time you want to pull out but she says no.
Ok sorry but I will summarize as short as possible. I have a stupid entertainment drywall niche. it's 2feet deep by 10feet wide. That said I have ml 60xt tower speakers, and I think they would sound better if I could only pull them out another 2 feet but I can't due to aesthetic reasons, ok its mostly my better half that won't let that fly. So are there any towers under 10k that would work or should I be looking at bookshelves with subs. my the living room is about 20 x 20 with 10feet ceilings.
