With 70V compatibility and a 360° swivel bracket, they offer flexible installation and balanced sound coverage.

What You’ll Need:

Rockville Cube 70V speakers
Speaker wire (red = positive, black = negative)
Compatible 70V amplifier
Mounting hardware (included)
Optional: safety chain (included)

Step-by-Step Instructions

1. Understanding 70V Speaker Systems

70V systems allow you to run many speakers from a single amplifier.
Each speaker draws a fixed wattage based on your selection (1.5W, 3W, or 6W).
Match total wattage of all speakers to your amplifier’s wattage capacity.
Example: A 100W amp can support twenty 5W speakers.

2. Adjusting the Wattage Tap

Each Cube speaker has a built-in transformer and tap selector:

Locate the quick-disconnect Euroblock terminal on the back.
The black wire (ground) always connects to terminal “C.”
The red wire (positive) connects to your chosen tap:
- 1.5W tap for quieter background use
- 3W tap for medium volume
- 6W tap for louder playback

3. Connecting the Wires

Strip the speaker wire ends.
Insert the red wire into the selected tap terminal.
Insert the black wire into the C (common) terminal.
For daisy-chaining (parallel wiring):
- Run speaker wire from the positive terminal of one speaker to the positive of the next.
- Repeat for the negative terminal.
- Continue this pattern until all speakers connect back to the amplifier.

4. Mounting the Speakers

Choose your wall location.
Attach the main bracket securely to the wall.
Insert the ball joint into the bracket and fasten the cover.
Optionally, attach the included safety chain for extra security.
Aim the speaker using the 360° swivel design to achieve optimal coverage.

5. Using a Multi-Zone Amplifier (Optional)

Each zone can have independently tapped speakers.
Make sure not to exceed the wattage limit of any zone.
Set different volume levels for separate areas (e.g., dining area vs. bar).

Troubleshooting & FAQs

Q: Why aren’t my speakers turning on or playing sound?

Double-check the tap connections. Make sure red and black wires are in the correct terminals.
Verify your amplifier is powered on and set to the correct zone/output.

Q: Can I mix these speakers with other brands or ceiling speakers?

Yes, as long as all speakers in the system are 70V compatible.

Q: What’s the benefit of using 1.5W vs. 6W tap?

Lower wattage = softer volume, more speakers per amp
Higher wattage = louder volume, fewer speakers per amp

Q: Is the mount really 360 degrees?

Yes, the ball joint allows you to angle the speaker in virtually any direction for optimal sound dispersion.
