Überlegungen zur Platzierung
- Standort: Subwoofers are less directional than full-range speakers, offering more flexibility in placement. Experiment with different wall locations to find the best bass response for your room.
- Bolzen: Use a stud finder to locate wall studs. The subwoofer requires a clear opening between studs. Ensure the chosen location avoids electrical wiring, plumbing, or other obstructions.
- Tiefe: Verify that the wall cavity depth is sufficient for the subwoofer (5.5 inches / 140 mm).
Installationsschritte
- Mark the Opening: Use the provided template (if included, or measure the speaker dimensions) to trace the cutout area on the wall. Ensure the outline is level.
- Schneiden Sie die Öffnung aus: Carefully cut along the traced line using a drywall cutter or utility knife.
- Lautsprecherkabel verlegen: Route CL2-rated speaker wire from your amplifier to the wall opening. Leave enough slack for easy connection.
- Prepare Mounting Ears: Before inserting the speaker, it is recommended to tighten and then loosen each mounting screw on the speaker's frame. This ensures the mounting ears are free to engage properly.
- Lautsprecherkabel anschließen: Connect the speaker wires to the subwoofer's binding posts. Ensure correct polarity (+ to + and - to -). The subwoofer features push-type binding posts.
- Insert Subwoofer: Carefully insert the subwoofer into the wall opening.
- Sicherer Subwoofer: Tighten the mounting screws on the front baffle. This will rotate the mounting ears behind the drywall and secure the speaker in place. Do not overtighten.
- Attach Grill: The subwoofer comes with a paintable magnetic grill. Align the grill with the speaker frame; the magnets will hold it in place. You may paint the grill to match your wall color if desired.
