What are the weather-resistant design features of the RUSSOUND OB-4.1?
The RUSSOUND OB-4.1 speakers are designed to handle harsh environments, including rain, snow, saltwater, and UV rays. Key design features include:
Gold-plated binding posts.
Solid brass and stainless steel hardware.
Rust-proof aluminum grille.
Resonance-free, mineral filled composite cabinet that can withstand temperature fluctuations from -50F to 200F.
How do I connect the wiring to the RUSSOUND OB-4.1 speakers?
The gold-plated binding posts on the RUSSOUND OB-4.1 are color-coded for polarity: red is positive and black is negative. These posts accept either bare wire or banana plugs. To ensure a safe and proper connection, follow these steps:
1. Turn off the amplifier before making any connections to avoid damage from accidental speaker wire shorting.
2. Ensure all connections are tight and that there is no shorting of wires from one terminal to another.
3. Verify that the polarity is correct on both speakers, as incorrect polarity will cause poor bass response and imaging due to cancellation.
How should the RUSSOUND OB-4.1 Solo model be connected?
For the Solo version of the RUSSOUND OB-4.1, attach each pair of wires to the red and black speaker terminals. Press down on the gold-plated binding post and insert the wire into the hole. Release the binding post to secure the wire. Ensure that no stray strands of wire have detached and are touching the other main wire.
What is the correct mounting orientation for the RUSSOUND OB-4.1?
When mounting the RUSSOUND OB-4.1, do not position the speaker with the front facing up. Mounting it in this orientation can allow water to enter the cabinet directly through the port opening.
How do I mount the RUSSOUND OB-4.1 using the included standard bracket?
The RUSSOUND OB-4.1 includes mounting brackets that allow for either vertical or horizontal mounting. Follow these procedures for installation:
1. Use a level when mounting the brackets to ensure correct positioning.
2. Ensure the mounting surface and fasteners are strong enough to support the speaker safely.
3. Connect the speaker wiring, ensuring the correct polarity.
4. Secure the speaker to the bracket using the supplied knobs.
5. Adjust the speaker for optimal sound and hand-tighten the knobs only. Do not use power tools, as they can damage the threaded inserts and cause them to break free from the cabinet.
Can I use an aftermarket bracket with the RUSSOUND OB-4.1?
Yes, the RUSSOUND OB-4.1 is equipped with dual 1/4-20 brass inserts. These are designed for use with various aftermarket mounting systems. When using these, follow the specific directions provided with the aftermarket product.
