10.3
High Frequency Driver
The high frequency driver has a field replaceable driver/voice coil assembly. The high frequency horn/driver
assembly is retained by brackets secured to the inside of the bass horn and eyebolts secured to the LF driver.
To remove the driver, first remove the grille. Then disconnect the Molex plug from the side of the cylindrical
phase plug housing behind the HF horn itself. Remove the 4 Phillips head screws that attach the eyebolts to the
LF driver frame. Then detach the entire HF driver/horn/LF phase plug assembly from the enclosure by removing
the four 1/4-20 hex head bolts and nuts that secure the HF brackets to the R1 bass horn. Note the orientation
of the horn assembly to the enclosure so as to re-install it correctly. Remove the 4 Phillips head screws from
around the rear horn flange and lift out the HF driver. Detach the wiring to the driver noting the polarity of the
connections for later correct attachment (See FIGURE 5). The driver may then be unbolted from the HF horn.
To reinstall, reverse this procedure, ensuring proper orientation of the horn. Be careful to avoid damaging the
LF driver cone with the eyebolts or back of the phase plug when putting the assembly back into the low
frequency horn. Also avoid damaging the inside of the horn with the horn brackets.
10.4
Low Frequency Driver
This driver is accessed by first removing the high frequency horn/driver assembly as detailed in SECTION 10.3.
The low frequency driver can then be removed by unscrewing the 4 remaining Phillips head bolts from the
enclosure. Detach the wiring to the driver noting the polarity of the connections for later correct attachment (See
FIGURE 5). To reinstall, reverse this procedure.
10.5 Crossover
The crossover is located inside the low frequency phase plug attached to the rear of the high frequency
horn/driver assembly. It is accessed by first removing the high frequency horn/driver/phase plug assembly as
detailed in SECTION 10.3 then removing the phase plug from the back of the HF horn/driver. Remove the
crossover by unscrewing the 8-32 nut and bolt that hold it to the rear of the phase plug. For complete removal
you must detach the Molex plug from the phase plug which is held on by hot melt glue that can be cut away.
Alternately you can either cut the wires from the plug to the crossover or unsolder the wires from the crossover
board. To reinstall, reverse this procedure ensuring that the crossover is oriented so that it does not contact the
eyebolts in the bottom of the phase plug. Reattach the Molex plug into the side of the phase plug using hot melt
glue or reattach the wires if they were cut or unsoldered. If cut, be sure to insulate any bare wire where you
reconnect them.
