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

of rated nput power and e ther one

percent (1%) of rated nput power or one

Watt, wh chever s greater. D stort on s

read from the graph as the d fference

between the fundamental s gnal

curve that s down 40 dB from the

fundamental s equ valent to 1% d stort on.
