here are few concepts in manufacturing

more hallowed than the "skunk works," a

design group that operates outside the

mainstream of the corporation that employs

them. The name was coined to describe a Lock-

heed facility in Palmdale, California that has

produced some of the world's most extraordinary

jet aircraft. Only 80 miles away, in the nondescript

suburb of Pomona, another skunk works has

been flourishing for more than a decade. In this

backwater of Pioneer's worldwide operations,

surrounded by shelves of raw drivers and carcass-

es of past prototypes, Pioneer chief speaker de-

signer Andrew Jones and his crew have designed

everything from $40-per-pair minispeakers to the

$60,000-per-pair TAD Reference One towers.

Jones's team has recently focused on archi-

tectural speakers — i.e., in-wall and in-ceiling

models. Extra effort went into the models de-

signed for Pioneer's high-end Elite line, which are

intended to compete with the world's most sto-

ried speaker brands.

The Pioneer Elite architectural speakers are

notable for their concentric drivers, which use

11/2-inch titanium tweeters mounted in the

center of various woofers. Pioneer refers to its

concentric designs by the acronym CST, for Co-

herent Source Transducer.
