SETTING UP YOUR ULTRA SPEAKERS

ACOUSTICS & ROOM PLACEMENT

Front Left/Right Loudspeaker Placement and Room Acoustics:

Proper placement of the front left/right speakers is essential to achieve the smoothest frequency

response, optimal stereo imaging and the most spacious, three-dimensional soundstage.

Stereo imaging and soundstage are affected by loudspeaker location and the listening position,

relative to each other and room boundaries. Moving the loudspeakers away from room boundaries

will tend to improve stereo imaging and spaciousness by attenuating and delaying boundary

reﬂections, thus optimizing direct sound and helping to preserve spatial information in the

recording.

The amount of exposed glass, drywall and bare ﬂooring in the room will increase the amount of

reﬂected sound and exacerbate problems like slap echo and ringing. Conversely, furnishings like

carpeting, drapes and upholstered furniture will reduce the amount of reﬂected sound in the room.

The ratio of direct-to-reﬂected sound and the decay characteristics of the listening environment will

have a large inﬂuence on the ultimate sound quality of any loudspeaker system. Dedicated room

treatments like absorbers, diffusers and bass traps can greatly improve the sound quality of any

listening environment, and are encouraged to extract the absolute best performance from any

high-end loudspeaker system.

the ratio of direct-to-reﬂected sound, so experimentation with toe-in is recommended to obtain

optimal results.

from boundaries and corners will reduce the bass response. Due to the complex interaction of the

loudspeakers with nearby boundaries/corners and your listening position, signiﬁcant changes to the

bass response can occur with very small changes in either loudspeaker location or listening

position, so experimentation with both placement and listening position is recommended to obtain

optimal results.

insert the foam port plug to slightly below ﬂush

of the port ﬂare. Inserting the foam port plug

creates a low-Q sealed acoustic alignment, and

results in an earlier roll-off of the bass response.

This will often be a better complement to the

acoustics of a smaller tightly-enclosed listening

environment, resulting in a more balanced and

natural-sounding bass response.
