Some speakers work for near field better than others.I only had them for short time but a pair of Audio physic Sparks were fun since they were narrow florstanders easy to pull up away from wall and then put back.Those "near field" sessions gave up some bass but added to sound stage depth and speaker itself lent itself to doing so easily.Other large speakers or even monitors aren't as easy to move around.But some speakers require different distance from wall which everyone knows but some speakers like studio monitors are designed to listened to up close.But Hartley's rule of thumbs is good starting point before you start moving them around to find optimal placement.Some speakers sound lousy and are difficult set up some aren't.A lot of speakers just snap into focus with small changes in placement.
