The one time you want to pull out but she says no.

Plus one @twoleftears and I’ll add, put some masking tape on the floor to mark where your speakers sound their best, so you can easily put the speakers back when you want and you won’t have to fiddle whit getting them just right again.

If this isn’t an option, look for speakers that are ported in the front , not in the back,.  They don’t have to be pulled out nearly as far. Some only need a few inches!

All the best.

Check out Volti Audio Razz. Really good, very efficient, front ported & will likely sound good against the wall although imaging for virtually any speaker might suffer a bit positioned this way. 

Have you tried a different position? Can you turn the speakers on their side?

Ohm Walsh Talls will cast a wide stage and work well close to walls. 

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.
