MODEL X825 — The X825 crossover network is designed for use with the Electro-
Voice TlOA driver unit and 8HD Hoodwin diffraction horn. The X825 is of */4
section and finds application in medium efficiency systems employing E-V 12BW,
SPI2B and TlOA drivers such as the Aristocrat I and LA, Regency I and 1A and
Empire I and IA.
MODEL X36 — The X36 crossover network is designed for use with the Electro-
Voice T35 and T35B Super-Sonax VHF driver units.
MODEL X336 — The X336 crossover network is designed for use in the Electro-
Voice Georgian <f-wav loudspeaker system. Model 105. Frequencies below 300
cps are fed to the 15WK low-frequency driver, the frequencies between 300 and
3500 cycles to the 848HF compound coaxial mid-range driver, and those above
3500 cps to the T35 Super-Sonax VHF driver.
MODEL X2635 — The X2635 crossover network is designed for use in the Electro-
Voice Patrician and the Residence Entertainment Center. The X2635 uses a
•4-section constant-K 200 cps network with •/^-section networks for the higher
frequencies. Because of the inherent high-frequency cutoff of the low-frequency
horns used in both the Patrician and Residence Entertainment Center, rapid
attenuation is not required in the low-frequency crossover.
Typical applications of Electro-Voice networks are shown in Figures 1 and 2.
Figure 1 illustrates a single crossover used to separate frequencies radiated by
a T35 or T 35 B Super-Sonax VHF driver, and a low-frequency or coaxial low-
range speaker.
Figure 2 is typical of a cascaded application in which two crossover networks
are employed. It is not important in which order the crossovers are cascaded,
the purpose of such an arrangement being merely to insure a pass band fre¬
quency response for the treble mid-range driver.
Although these crossovers have been designed for use in 16-ohm systems, they
may be employed in other situations. For instance, if a 16-ohm unit is used in a
system in which both the input and output impedances are 8 ohms, no appreciable
shift in crossover frequency will be experienced, although the insertion loss of
the crossover will be greater. In the case of reproducers with unequal im¬
pedances, the crossover should be connected to a 16-ohm source. As an example,
if an 8-ohm woofer is used with a 16-ohm tweeter, the reproduction of bass will
be favored; however, if the tweeter was an 8-ohm unit and the woofer 16 ohms,
then treble reproduction would be relatively louder.
Complete instructions and information on the assembly of E-V drivers and systems
are included with the individual driver units and packed with each E-V enclosure.
