Bass Drivers

The bass driver pictured below serves as the foundation of the S-

3EX speaker system. The driver's strength is the result of the

Aramid/Carbon composite material, originally created during the

development of the S-1EX, that is used in its diaphragm. Pioneer's

exclusive LDMC magnetic circuit technology has been

incorporated in order to preserve linearity from low to high output

levels and minimize distortion.

Bass Enclosure Construction

The unique form of the S-3EX is based upon logical necessity. In

order to synchronize the arrival time of sound from the CST and

the two bass drivers, each driver is mounted upon a baffle that

serves to create a highly delicate curve known as the "precision

curve" (see illustration below). Made of up to 100 mm thick MDF

(Medium Density Fiberboard), this baffle is, moreover, strong

enough to contain the force of the drivers. Additionally, the bass

port has been carved out of an extremely thick block of MDF,

resulting in the reduction of wind noise for clear, deep bass.

Crossover Networks

The crossover networks use only the finest components. Air cored

coils, noninductive resistors, and film capacitors in the signal path

are all carefully chosen and optimized for the CST driver to provide

the greatest transparency to the signal. The bass drivers use

silicon steel plate core inductors that minimize distortion and loss

during energy transfer. All components are connected directly to

their respective wiring materials, instead of a printed circuit-

board, allowing for minimal loss and maximum performance.

Collaboration with Air Studios

Since its establishment by George Martin in 1969, London,

England's Air Studios has earned unequivocal respect from

scores of artists who recognize it as the world's premier recording

studio. The Air Studios seal that was awarded to the S-3EX

indicates that these speakers are capable of producing the high-

quality sound demanded by the world's top-class sound creators.
