Description
The Quadra™ 10 s an nject on-
molded, two-way speaker system,
eng neered n the AA trad t on to prov de
super or performance from a compact and
durable package. The enclosure s made
from very h gh mpact, nject on-molded
polypropylene n a trapezo dal shape, w th
extens ve r bb ng and brac ng, and the gr lls
ut l ze perforated metal protected by a h gh
qual ty v nyl coat ng process, and has an
ntegral foam nner layer for env ronmental
protect on.
The two-way system s compr sed of a
10" long throw heavy-duty woofer, and a
water-res stant treated cone and dust cap
for super or env ronmental stab l ty. The h gh
frequenc es are handled by a 14XT™ 1.4"
t tan um d aphragm compress on dr ver,
coupled to a 1" Quadrat c Throat Geometry
horn, molded ntegral to the cab net. Th s
horn prov des outstand ng d spers on
coupled w th a well-controlled pattern, and a
smooth, even response.
Ut l z ng Quadrat c Throat Horn™
technology, under US patent 6,059,069, the
horn has lower d stort on than many popular
CD horn geometr es.

The nternal pass ve crossover
features Sound Guard™II tweeter protect on

h gh performance components, to prov de

roll-off and protect on, as well as dr ver EQ
for the woofer and horn; the sum total s a
crystal clear and very smooth response.
H gh-qual ty, rel able crossover components
nclude polypropylene capac tors, and h gh
current nductors and nput connectors. The
opt mal ntegrat on of the crossover w th the
selected dr vers results n a smooth
frequency response from 74 Hz to 18 kHz.
Desp te ts compact d mens ons, th s
enclosure can put out some very ser ous
sound levels, and take 500 Watts program
of clean ampl f er power, result ng n an
outstand ng amount of clean coverage w th
amaz ng clar ty.
Frequency response
Th s measurement s useful n
determ n ng how accurately a g ven un t
reproduces an nput s gnal. The frequency
response of the Quadra 10 s measured at a
d stance of 1-meter us ng a 1 Watt ( nto the
nom nal mpedance) swept-s ne nput s gnal.
As shown n f gure 1, the selected dr vers n
the Quadra 10 comb ne to g ve a smooth
frequency response from 74 Hz to 18 kHz.

Power Handling
There are many d fferent approaches
to power handl ng rat ngs. Peavey rates th s
loudspeaker system’s power handl ng us ng
a full-range form of the AES Standard 2-
1984. Us ng aud o band 20 Hz to 20 kHz

user that every port on of th s system can
