Equalization Controls
Here is a brief introduction to each of the Speaker Equalization
control frequencies and what their aect on your music is.
75 Hz – Bass. This is at the bottom end of the frequencies which
typical in-wall and small bookshelf speakers can achieve. Even
though the Architect’s subsonic lter cuts frequencies under
40 Hz, boosting this band more than 6 dB can cause distor-
tion. Adjust this band with care. A mild boost will enhance bass
instruments such as bass guitar, kick drum, oor toms, timpani
and double bass violas.
250 Hz and 700 Hz – High and low midrange. These controls
directly aect the sound of instruments and vocals. These
bands also determine the speaker’s presence (whether the
music sounds far away or close in). Small speakers often pro-
duce too much midrange, so these controls are candidates for
being turned down slightly during your initial experimentation.
Denitely consider reducing 700 Hz if you are only using your
extension speakers for background music.
2500 Hz – Treble. Female vocals and the “edge” of instruments
such as guitars, snare drums, saxes, violins, etc. are found in
this range. If accentuated too much (by boosting this control)
sounds in the 2500 Hz range can seem harsh and fatiguing to
the ear due to excessive output by the speaker or because of
live, reective room acoustics.
12 KHz – High treble. The ne detail, texture and sheen of mu-
sic is found here. The breathiness of vocals, the sheen of cym-
bals, the high overtones of piano and strings. Actually, there’s
audible music information up to 20,000 Hz on some CD’s and
most adult’s hearing is still pretty good at 15,000 Hz. But we’ve
chosen 12,000 Hz because it provides more useful control to
compensate for room acoustics and common small-speaker
deciencies.
