Unpacking System Components

•Keep the original carton and packing materials for future shipment or storage.

•Check for any visual signs of damage. If you encounter any concealed damage, consult your Earthquake Sound dealer before proceeding with unit installation.

•Retain the sales receipt as it establishes the duration fo the limited warranty and provides information for insurance purposes.

System Installation Considerations

There are several factors to consider before installing Earthquake Sound’s iQuake-52.

•What are the intended listening zones?

•What system options and accessories might be required for features such as local sources, etc.?

•From where in each zone will the listener prefer to control the system? Where will the remote gains be located? Where will the speakers be located?

•Where will the source equipment be located?

Connection Tips

•Keep all power cords away from all signal cables to prevent humming from induced noise.

•Choose reliable signal cable cords (Earthquake Sound also specializes in high performance RCA cables and patches).

•All speaker wires that are ran through the walls should be twisted type to reduce potential hum noise pick-up.

•Label both ends of all wires with the corresponding room location.

•It is best to use a grounded electrical outlet to power the amplifier. Lack of input ground reference could be unsafe. Consult with your electrical contractor about proper grounding.

IQ-52P, IQ-52S, IQ-52R specifications

Earthquake Sound has a long-standing reputation for delivering powerful and innovative audio solutions, and their IQ series subwoofers, namely the IQ-52R, IQ-52S, and IQ-52P, demonstrate that commitment to quality and performance. These subwoofers are engineered to bring an impressive depth of sound to any audio system, catering especially to bass enthusiasts who appreciate low-frequency response in music and home theater applications.

The IQ-52R is a robust, rear-firing subwoofer designed for maximum performance and flexibility. One of its standout features is its powerful 500-watt RMS power handling, allowing it to reproduce deep bass with clarity and impact. The rear-firing design enhances the coupling of the subwoofer with room boundaries, providing an immersive audio experience. The enclosure is built with high-quality MDF, adding to its durability while minimizing unwanted resonance.

Meanwhile, the IQ-52S serves as a side-firing subwoofer, which offers a slightly different placement option for audiophiles. The side-firing orientation allows it to be positioned against a wall without compromising sound quality. With the same impressive power handling and a frequency response down to 25 Hz, the IQ-52S excels in delivering that low-end rumble that is essential for movie soundtracks and music. Its front-mounted controls allow for easy tweaking of volume and phase settings, accommodating a variety of room acoustics.

The IQ-52P rounds out the series as a ported subwoofer, which enhances airflow and increases efficiency, thus delivering louder bass at lower frequencies. The ported design complements this model’s 500-watt power handling, ensuring it can fill larger spaces without losing bass quality. This subwoofer is equipped with advanced circuitry that protects its components from overheating and distortion, ensuring long-term reliability.

Across the IQ series, Earthquake Sound employs technologies such as advanced digital signal processing and high-efficiency amplifiers to optimize performance. Each model is also equipped with various connectivity options, making integration into existing audio systems seamless. The IQ-52R, IQ-52S, and IQ-52P are designed to work both individually and in combination, providing users with the flexibility to create a bass response tailored to their specific environments and preferences.

In summary, Earthquake Sound's IQ series subwoofers are a testament to superior engineering, offering exceptional sound quality, versatility, and robust construction.
