5、edures may require the user to partially disassemble the unit. Refer to the Disassembly/Assembly Procedures section for specific instructions. 1. Woofer Rub and Tick Test Connect a signal generator to a power amplifier. Adjust the generator frequency to 10 Hz and the amplifier output to 5 Vrms. Conn

6、ect the amplifier output to the drivers input terminals. The input terminals are molded in the driver housing near the barrier strip. Refer to Figure 1. No extraneous noises such as rubbing, scraping or ticking should be heard. 2. Air Leak Test Plug the end the of the barrel. Adjust the oscillator f

7、requency to 10 Hz and the amplifier output to 5 Vrms. Apply the signal to the positive and negative inputs of the speaker. For at least 5 seconds, listen for air leaks around the driver basket edge, driver housing seal area, barrier strip, or the drivers dustcap and cone surround. Repair leaks aroun

8、d the driver by removing the driver and replacing the gasket under the driver flange. 3. Phase Test Set a DC power supply to 8 volts. Connect the positive (+) supply lead to the positive (+) speaker input terminal and the negative (-) supply lead to the negative (-) speaker input terminal. The woofe

9、r cone should move outward. NOTE: Supply voltage should only be momentarily applied to the speaker input terminals to avoid possible damage to the speaker. 4. Sweep Test Apply a 15 Vrms, 25 Hz signal to the speakers input connectors. Sweep the oscillator from 25 Hz to 125 kHz, there should not be an

10、y buzzes, rattles or extraneous noise. There should not be any buzzes or rattles from within the speaker cabinet. Redress any wire or component that buzzes. Figure 1.

11、he item callouts in Figures 1 and 2. 1. Driver Removal (Refer to Figures 1 and 2) Note: Use Step 1.1 to disassemble the short 3ft driver barrel (14) from the 9ft barrel (15). 1.1 Use a 3/8 hex-head wrench to remove four flange bolts (3), locknuts (4) and washers (5) that holds the driver housing (1)

12、 and flange cover (2) together. 1.2 Use a hex-head wrench to remove the eight bolts (6) that mount the driver (7) to the driver housing. 1.3 Use a flat-head screwdriver to pry the driver out from the driver housing. Do not let the driver fall out beyond the distance of the wiring harness (8). To rem

13、ove the risk of damage to the driver, its advisable to have two people perform this step. 1.4 Remove the two connectors (part of the wiring harness (8) from the drivers terminals. 1.5 Remove the driver from the housing. 2. Driver Replacement (Refer to Figures 1 and 2) 2.1 Place the driver gasket (9)

14、 into the driver housing (1). Align the screw holes in the gasket with the screw holes of the driver housing. 2.2 Connect the two connectors from the wiring harness (8) to the terminals of the new driver (7). 2.3 Bolt the driver into the driver housing by tightening eight bolts (6) with a hex-head w

15、rench. 2.4 Assemble the 3ft driver barrel (14) and the 9ft barrel (15) by matching up the interlocking tabs on the driver housing (1) and flange cover (2). 2.5 Tighten four flange bolts (3), locknuts (4) and washers (5) with a 3/8 hex-head wrench.
