If your listening room layout (for practical or
aesthetic reasons) locates most of the listeners
close to the rear wall, the resulting bass level can
be sufficiently reinforced by the boundary that the
overall sound becomes "boomy". THX Select2 Plus
receivers contain a Boundary Gain Compensation
(BGC) feature to improve bass balance.

THX Loudness Plus
THX Loudness Plus is a new volume control
technology featured in THX Ultra2 Plus™ and
THX Select2 Plus™ Certified receivers.
With THX Loudness Plus, home theater
audiences can now experience the rich details in
a surround mix at any volume level.
A consequence of turning the volume below
Reference Level is that certain sound elements
can be lost or perceived differently by the listener.
THX Loudness Plus compensates for the tonal
and spatial shifts that occur when the volume
is reduced by intelligently adjusting ambient
surround channel levels and frequency response.
This enables users experience the true impact
of soundtracks regardless of the volume setting.
THX Loudness Plus is automatically applied when
listening in any THX listening mode. The new THX
Cinema, THX Music, and THX Games modes are
tailored to apply the proper THX Loudness Plus
settings for each type of content.
