When calculating how far off the back wall you have placed standard floor standing speakers, do you measure from the front of the speaker (fixed) or the back (varies from speaker to speaker)?
Also, does anyone make speaker sliders or rollers that will allow the listener to slide heavy floorstanding back and forth? 99% of speakers in the home when placed optimally for 2 channel stereo, are in the middle of the room, too close to the listening position and/or blocking doorways and walkways.
Lastly, has anyone had any luck getting the smaller Magnepan speakers (MMG or LRS) to sound good when placed only 3’ off the wall? Their optimal placement of 6’ will work in probably less than 1% of most homes.
