Introduction
The Rockville RVP15W8 is a 15-inch 8-ohm replacement woofer designed for use in passive subwoofers, PA speakers, guitar/bass amplifiers, and cabinets. This guide will walk you through removing an old woofer and installing the RVP15W8 in different types of enclosures.
Important Safety Precautions
- Unplug any powered speakers or amplifiers before replacing the woofer.
- Disconnect passive speakers and subwoofers from any amplifier or mixer before installation.
- Handle speaker wires carefully to avoid damage.
Replacing the Woofer in a Passive PA Speaker
Step 1: Remove the Speaker Grille
- Unscrew the grille screws on the front of the speaker using a screwdriver or drill.
- If the grille is difficult to remove, use a flathead screwdriver or butter knife to pry it off carefully.
Step 2: Remove the Old Woofer
- Unscrew the woofer mounting screws using a screwdriver or drill.
- Carefully lift the woofer out to expose the internal wiring.
Step 3: Disconnect the Wires
- If the wires are soldered, clip off the ends and strip the insulation to expose the bare wire.
Step 4: Connect the New Woofer
- Unscrew the terminals on the RVP15W8 woofer.
- Insert the positive wire into the positive terminal and tighten it.
- Insert the negative wire into the negative terminal and tighten it.
- Ensure a secure connection before reinstalling the woofer.
Step 5: Mount the New Woofer
- Align the screw holes on the woofer with those on the speaker enclosure.
- Screw the woofer into place.
- If the logo alignment matters to you, you may need to create new screw holes.
Step 6: Reattach the Grille
- Align the grille with the speaker.
- Screw the grille back on securely.
Now, your PA speaker is ready for use with the new woofer installed.
Replacing the Woofer in a Subwoofer
The process is identical to replacing the woofer in a PA speaker:
- Remove the grille to expose the woofer.
- Unscrew and lift the old woofer.
- Disconnect the wires, clip, and strip if necessary.
- Connect the wires to the new woofer terminals.
- Secure the woofer to the enclosure.
- Reattach the grille.
Your subwoofer is now ready to deliver deep bass with the new RVP15W8.
Replacing the Woofer in a Guitar or Bass Amplifier Cabinet
If your amplifier or cabinet has two speakers, the process is slightly different.
Step 1: Remove the Old Speakers
- Unscrew and remove both speakers.
- Disconnect the wires (some amps use spade connectors).
Step 2: Connecting the New Speakers
- If keeping spade connectors:
- Strip extra speaker wire.
- Wrap it around the spade connectors.
- Secure with electrical tape.
- Connect the other end to the new woofer's terminals.
- If removing spade connectors:
- Clip off the ends.
- Strip the wire.
- Connect it directly to the woofer terminals.
Step 3: Parallel Wiring (If Applicable)
If the amplifier runs speakers in parallel:
- Connect both positive wires to the positive terminal.
- Connect both negative wires to the negative terminal.
Step 4: Mount the New Speakers
- Align the screw holes of the woofer to the cabinet.
- Screw them in securely.
Your guitar/bass amp or cabinet is now ready for use.
Conclusion
Replacing a woofer in a PA speaker, subwoofer, or amplifier cabinet is a straightforward process. Whether you're upgrading or replacing a damaged speaker, the Rockville RVP15W8 provides reliable performance and deep bass.
