Crossover Networks
Model X36
Electro-Voice crossover networks are high-Q low insertion loss, frequency dis¬
criminatory filters designed for use in systems having a characteristic impedance
of 16 ohms. All E-V crossovers are of the constant-K configuration. A basic
advantage of the constant-K-type filter is that identical values of components may
be used in both scries and shunt arms; thus, identical phase rotation and transient
response are insured on either side of the crossover frequency.
E-V crossovers are designated by the 3 db down point in the network frequency'
response curve. For example, the high-pass section of the X8 crossover is 3 db
down at 800 cps, as is also the low-pass section. Attenuation in Electro-Voice
networks takes place at the rate of 12 db per octave for section filters and
6 db per octave for -section networks.
Because high-Q air-core inductors are used in these crossover networks, filter
characteristics are maintained constant despite changes in average values of
program level. Electro-Voice crossovers will safely handle up to 100 RMS watts.
Since the average level of program material in home listening rarely exceeds 2
watts, the safety' margin inherent in the design of these units is indeed a large one.
All Electro-Voice crossover networks are housed in drawn steel cans. Finish is
gray and the component parts are potted in a thermoplastic asphalt.

MODEL X425
— The X425 crossover network is designed for use with most E-V
woofers or coaxial drivers in an infinite baffle when it is desired to cross over
to the mid range from the bass driver at a lower frequency.
MODEL X6
— The X6 crossover network is designed for use with the Electro-
Voice T25A or T10A driver units and 6HD Hoodwin diffraction horn.
MODEL X8
— The X8 crossover netw'ork is designed for use with the Electro-
Voice T25A or T10A driver units and
8
HO Hoodwin diffraction horn. The
X8
is used in both the Aristocrat
II
and
III
systems, the Regency
II
and
III
systems,
and the Empire
II
and
III
systems.
