Sonodyne Avant S1 - Manual (Page 4)

AMPLIFIER SELECTION
We recommend using amplifiers whose continuous (rms) power per channel
is greater than or equal to that the Avant 150 handles. In the event that the
power is greater, care must be taken to avoid playing music at excessively
loud levels and thus damage the speaker. Also, while using an amplifier
with rms power lower than the rated power handling of the Avant 150,
please ensure that the amplifier level is kept a few steps below
maximum level. Lower powered amplifier, operating at close to max, often
produce distorted signals, or very powerful musical signals. This can lead to
damage of the high frequency driver, the tweeter.
ACOUSTICS OF THE LISTENING ROOM
The acoustical makeup of your listening room is key in determining how
good (or bad) is the sound that reaches your ear. The contents of a room
(carpets, curtains, furniture etc.), its shape, and the material of which the
boundaries are made, make or break your sound. The idea is to have a
listening area where the absorptions and reflections are calibrated to attain,
as far as possible, a neutral environment. While there are no 'quick fix'
formulae to convert a room to an 'ideal listening room’, here are some
things that you might try to attain optimal performance.
In your listening room, clap your hands, snap your fingers, and jingle a ring
of keys.
If the resulting sound is unintelligible (muffled), and resonating, your room
is inclined toward being reflective. In this event, you might want to: Hang up
curtains/ Lay a carpet or rug / Introduce book cases/other racks. In the event
that the resulting sound is too damped your room is inclined toward being
absorptive. You might want to remove some of the absorptive material (like
those given above).
