9.2 Rationale
There is an old saying, "There's no such thing as a free lunch." There are many trade-offs in speaker design, as in
almost any area one can think of. In this case, the trade off is between transient response and anechoic frequency
response (the speaker's frequency response in an anechoic chamber). Almost all manufacturers have chosen to
sacrifice transient response for improved anechoic frequency response.
At Avalon Acoustics, we have chosen to pursue a goal of complete freedom from resonances and stored energy to
ensure transient accuracy. Although this results in a slight sacrifice in one traditionally measured area, we feel
that the resulting gain in areas not traditionally measured results in audibly superior overall performance.
Anechoic Frequency Response vs. In-Room Frequency Response
It must be remembered that very little listening actually takes place in anechoic chambers. Placement of the
speakers in a real-world listening room will boost the bass response of the speaker, as explained in Section 8,
Room Acoustics and Speaker Placement, beginning on page 19. Since a loudspeaker with perfectly flat anechoic
frequency response will exhibit a low-frequency boost in a normal listening environment, a loudspeaker with a
gradual bass roll-off (in an anechoic chamber) can exhibit more accurate in-room frequency response. Avalon
Acoustics loudspeakers are carefully designed taking these factors into account. When placed in a variety of
representative positions in the room, Avalon loudspeakers will produce deep, accurate, and unexaggerated bass
response, with complete freedom from stored resonant energy.
