To change Screw the feet of Speakers and put it on the Back. Make sure that the Connecting sockets with damaged will. Loosen with a 1 / 8 inch bit, the two screws on the bottom of the cover.

Take off the lid. This the Velcro fasteners on the inside solved. It may be that there is something is difficult. Only courage to raise, you can Velcro dots at the end again .Detach Now turn to the loudspeaker and note the color of the tweeter ribbon cable.

Loosen now with a 1 / 8 inch bit, the lead of the tweeter. Now you can again with a 1/8 custom bit of the four screws tweeter ribbon remove. Place it afterwards to a safe location and make sure that no magnetic objects in its come close.

Now you remove with a 3mm bit first the lower and upper crossbar. These are not bonded but only loosely screwed on. Next remove all bolts from the lateral bars. The lateral ridges are bonded. To remove the bonding the solution is to use a correspondingly large screwdriver and drive it with cautious...

Now you can carefully lift the sidebar with the foil. Do the same with the another sidebar. Now remove the old panel and scrape with a putty knife the rest of the silicone and film remains from the wooden frame.
Page 7
Use the scraper to remove even the old foam residue which remains on the wooden frames. The upper parts of the framework must be thoroughly cleaned. Next, loosen the wiring of the crossover and remove the remaining aluminum and tape strips.
Page 8
Now relax the side-mounted screws until you effortlessly to 5 mm wide spacers between the frame and clamping bar can be used. Insert next to each clamping screw a spacer. Now glue all around the supplied foam rubber strips into the recesses provided for and press everything carefully with the role.

Now select it middle of the first and last with the help of a magnetic strip Eddings on the wood frame. This is important to be able to the tracks of the films precisely position. Often, these markings are however already available.

Now align the sheets along the rubber washers and making sure that the film is about anywhere Now you can apply the silicone to glue the sheets. Make sure you do not take too much. A 5 mm "sausage" is enough. Then put the film on the silicone and press the foil firmly careful.

Next, place the top bar on the film and lead all clamping screws iinto the holes provided in. Then you put enough weight on the sidebar, and let the silicone cure. Alternatively, you can also use clamps. Make sure that the running tracks of the film exactly parallel to the magnet and the upper and lower marker does...
Page 13
Now let the silicone cure for a day and repeat the next day the whole thing with the other side. You now have the opportunity possibly resulting wrinkles by pulling on the protruding foil to eliminate. You do not need to stretch taut the sheets, then this is done, the clamping screws.

When both sides are cured, you can first attach the upper part of the clamping section. They also use some silicone and screw it afterwards with square screws. Now look on the opposite side of the holes for mounting the top bar and beat with the help of the hollow punch at this very spot a hole in the foil.
Page 15
Then you can find the two holes in the top and bottom bar and also propose two holes through the foil. This ensures that you can stretch the film at the end without tearing it. Now you use the double-sided tape and fix the connection pads up and down on the wooden support.
Page 16
Now cut with the cutter, a hole in the foil where the captive nut is and apply a small amount of the included Speziallots on from the tube. Then they let the solder melt with a soldering iron and thus establish a secure connection.
Page 17
Now fix with a staple gun, a cable with sufficient cross section on the connection pad and solder it similar to previous ones. Connect the black cable from the terminal with a suitable cable sufficient cross section and guide both cables to the upper terminal pad To fix use superglue or other mounting option of your choice.

Look for the correct wiring of the tracks. Measure connect the ohmic resistance of the conductors. Between mass at the connection panel and the screw on the input sheet should be measured according to the model from about 3.8 ohms. Now you can remove one by one the spacer.
Page 19
Now you can adjust the resonant frequencies of the film. You will need an amplifier, a measurement microphone and a suitable audio measurement software such as ARTA, True RTA or DSSF3 To adjust the resonance frequencies the speaker into position first so that it can swing freely backwards or put him up with the help of a second person.
Page 20
Now you can mount the tweeter again. Pay attention to the correct polarity of the connection cable Thus, the main work is done. Now you still check the overall function of the speaker to make the all screws are returned to your desk all the wires are tight and nothing rattles. All projecting film remains carefully cut with a sharp utility knife.
