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, high frequency.

This methodology is guaranteed to produce sound with more dynamics, greater clarity and greater focus.
