Since every room is different and each type of speaker has a different acoustic radiation pattern, an engineering analysis must be performed using a test tone generator, with at least one test tone, 315 Hz works very well but you can use others too, say 100 Hz or 1000 Hz. You also need a SPL meter.
The objective is to locate sound pressure peaks in the room occur, in the 3-D space of the room since some standing waves occur out into the room. So, map out the room's sound pressure peaks that are 6 dB or higher than the average sound pressure in the room, obtained using SPL meter. Those locations are where you need to focus, using a variety of room treatments, absorbers, diffusers, echo absorbers, bass frequency traps, Helmholtz low frequency resonators, high frequency resonators, etc.
This methodology is guaranteed to produce sound with more dynamics, greater clarity and greater focus.
