Choosing the drivers for our two-way bookshelf speaker was
probably the easiest part of designing this system. Joe quickly
selected the Usher 9930 tweeter and the legendary 8945A
woofer.
Usher 9930: This tweeter uses a specially coated textile dome
that offers a flat frequency response and a very open and
detailed sound quality. A tuned rear chamber and a lightweight
ferro-fluid in the gap provide a well-dampened, low resonance
point, making for an easy crossover design.
Usher 8945A: The 8945A woofer is one of Usher's most popular
drivers which features their low distortion motor system and a
carbon fiber/paper blended cone. This driver provides powerful
bass without a harsh midrange, making it one of the best all
around woofers for traditional two-way speaker systems.
