The provided manual describes the NERO-MODQ2 and NERO-MODQ3, which are compact, high-fidelity speakers designed for various audio applications, including home theater and multi-room audio systems. These speakers are engineered to deliver clear and robust sound from a small footprint, making them suitable for environments where space is a premium but audio quality cannot be compromised.

Function Description:

The NERO-MODQ2 and NERO-MODQ3 serve as passive loudspeakers, meaning they require an external amplifier to operate. They are designed to reproduce audio across a specific frequency range, providing a balanced sound profile suitable for music, movie soundtracks, and other audio content. The MODQ3, with its dual woofers, is particularly well-suited for center-channel applications in a home theater setup, where clear dialogue reproduction is crucial. Its magnetic linking feature allows multiple MODQ3 units to be combined, offering flexibility for creating custom speaker arrays, such as a wider center channel or stacked configurations for increased acoustic output. The rotating aluminum logo on the MODQ3 adds a practical aesthetic touch, allowing the logo to be oriented correctly regardless of the speaker's mounting position (horizontal or vertical). Both models are designed for easy wall mounting using optional ball-joint steel brackets, providing versatile placement options.

Important Technical Specifications:

The manual provides detailed specifications for both the NERO-MODQ2 and NERO-MODQ3 models:

NERO-MODQ2:

Woofer: Features a 3" (80mm) Fiber-Glass Cone with a Rubber Surround, designed for durable and accurate bass and mid-range reproduction.
Tweeter: Equipped with a 1" (25mm) Silk Soft Dome tweeter, providing smooth and detailed high-frequency response.
Power Handling: Rated at 50W RMS and 100W Peak, indicating its ability to handle moderate to high power inputs from an amplifier.
Frequency Range: Covers 101Hz to 20kHz, offering a broad spectrum of audible frequencies.
Sensitivity: 85dB, which is a measure of how efficiently the speaker converts amplifier power into sound.
Impedance: 8 Ohm, a standard impedance that is compatible with most home audio amplifiers.
SPL (Sound Pressure Level): Capable of reaching a maximum of 101 dB (Peak 104 dB), indicating its potential loudness.
Termination: Uses 4mm Three Way Binding Posts for secure and reliable connection to speaker wires.
Grille: Features a Perforated Metal grille, providing protection for the drivers while allowing sound to pass through unobstructed.
Cabinet: Constructed from MDF (Medium-Density Fiberboard) with a Sealed, Acoustic Suspension design, which contributes to tighter bass response.
Mounting Hardware: Includes Built-In Key Hole Mounts for direct wall mounting.
Dimensions (HWD): Measures 8.11" x 4.76" x 4.84" (206mm x 121mm x 123mm), highlighting its compact size.

NERO-MODQ3:

Woofer: Features two 3" (80mm) Fiber-Glass Cones with Rubber Surrounds, enhancing its bass output and mid-range clarity, particularly beneficial for dialogue in center-channel applications.
Tweeter: Also equipped with a 1" (25mm) Silk Soft Dome tweeter for clear high frequencies.
Power Handling: Rated at 60W RMS and 120W Peak, offering slightly higher power handling than the MODQ2.
Frequency Range: Covers 100Hz to 20kHz, similar to the MODQ2, ensuring full-range audio reproduction.
Sensitivity: 85dB, matching the MODQ2's efficiency.
Impedance: 8 Ohm, ensuring broad amplifier compatibility.
SPL: Capable of reaching a maximum of 103 dB (Peak 106 dB), indicating its potential for higher loudness.
Termination: Uses 4mm Three Way Binding Posts for robust wire connections.
Grille: Features a Perforated Metal grille for driver protection.
Cabinet: Constructed from MDF with a Sealed, Acoustic Suspension design.
Mounting Hardware: Includes Built-In Key Hole Mounts for direct wall mounting.
Dimensions (HWD): Measures 11.25" x 4.76" x 4.84" (286mm x 121mm x 123mm), indicating a slightly taller profile due to the dual woofers.

Usage Features:

Versatile Placement: Both models can be mounted on walls using their built-in keyhole mounts or the optional NERO-MODQ-MOUNT ball-joint steel brackets. These brackets allow for adjustable positioning, enabling users to direct sound precisely where needed.
MODQ3 Magnetic Linking: A unique feature of the NERO-MODQ3 is its magnetic cabinet linking capability. Multiple MODQ3 units can be magnetically connected, allowing for flexible configurations. For instance, three MODQ3 speakers can be linked to form a left, center, and right channel setup, or two units can be stacked and wired in series (creating a 4 Ohm load) to double the acoustic output. This modularity provides significant customization options for various audio setups.
Rotatable Logo (MODQ3): The MODQ3 features a rotating aluminum logo. This allows users to pull out the logo plate, rotate it to the desired orientation (e.g., for horizontal or vertical mounting), and then release it back into place, ensuring the brand logo is always displayed correctly.
Binding Post Terminals: Both speakers utilize 4mm three-way binding posts, which offer a secure and versatile connection for various types of speaker wire, including bare wire, spade connectors, or banana plugs.
Compact Design: The compact dimensions of both models make them ideal for discreet installations in small rooms, offices, or as part of a larger multi-channel system without occupying significant space.

Maintenance Features:

Limited Warranty: OSD AUDIO provides a generous 10-year Limited Warranty against defects in materials and workmanship for all its speakers. This warranty covers the replacement of defective parts and correction of workmanship defects without charge for parts or labor, provided proof of purchase accompanies the claim.
Authorized Dealer Requirement: To ensure warranty validity and proper support, OSD AUDIO emphasizes purchasing products exclusively through authorized dealers and distributors. Products bought from unauthorized sources will not be honored under the existing warranty policy.
Return Merchandise Authorization (RMA): For repairs under warranty, customers must first obtain a Returned Merchandise Authorization (RMA) number by emailing customer service at RMA@audiogeargroup.com. This process ensures proper tracking and handling of service requests.
Proper Packaging for Returns: When returning a product for repair, it is crucial to pack it in a corrugated container with at least 3 inches of resilient material to protect the unit from transit damage. This prevents further damage that would not be covered under warranty.
Warranty Exclusions: The warranty explicitly excludes damage caused by abuse, accident, misuse, negligence, improper operation (including installation errors), or any products that have been altered or modified. It also does not cover products with altered, defaced, or removed identifying numbers (like serial numbers) or normal wear and maintenance.
Repair Policy: In cases where damage is due to excessive power application, voiding the warranty on those specific parts, repairs will be conducted based on the retail value of the parts and labor.
Product Replacement: OSD AUDIO reserves the right to replace returned products with items of equal value and performance. In such instances, minor modifications to mounting may be necessary, which are the responsibility of the user.
Installation Guidelines: The warranty is contingent on the unit being installed and used according to its written instructions. Any necessary repairs must be performed by OSD AUDIO or an agency specifically authorized by them in writing. Damage resulting from abuse or servicing by unauthorized personnel is not covered.

In summary, the NERO-MODQ2 and NERO-MODQ3 speakers are designed for users seeking high-quality, versatile, and compact audio solutions with robust construction and a comprehensive warranty, provided they adhere to the manufacturer's usage and maintenance guidelines.
