Record where you are starting

Measure from a consistent point on each cabinet to the wall behind it, and note the distance to the side walls. Record the chair position too. Without those references, moving things by eye makes it difficult to know which change helped. Keep left and right placement as symmetrical as the room reasonably allows.

Genelec explains that room boundaries and reflected sound affect the response heard at the listening position. Its placement guidance should be read as guidance for a system and room, not reduced to a rule that every speaker must sit a fixed distance from a wall. The speaker’s own manual may specify port clearance, boundary controls, or other constraints that take priority for that model.

Change one relationship at a time

Choose a few familiar recordings with clear bass lines and voices. Move both speakers by the same small amount while keeping their separation and angle consistent, then listen from the same chair position. Alternatively, keep the speakers fixed and compare a modest chair movement. Do not change placement, equalization, and playback level together if you want to understand the result.

Listen for consistency across notes rather than simply choosing the position with the most bass. One conspicuously loud note can make a setting seem impressive while hiding unevenness elsewhere. Repeat the comparison with more than one recording, since a single mix can mislead you about the room’s contribution.

Work within the room’s constraints

Allow the ventilation and connector space required by the manufacturer. Keep rear ports unobstructed and avoid pushing cables sharply against the wall. If the speakers provide boundary-compensation switches, use the manual’s recommendations and note each setting. Such controls are adjustments, not permission to ignore the physical placement requirements.

A room with a doorway on one side and a bookshelf on the other may never offer perfect symmetry. Prioritize a workable listening position and document the compromise. Do not move speakers into an unstable location to achieve an abstract distance. When the layout is settled, mark positions discreetly so ordinary cleaning or furniture movement does not erase the comparison you made.
