Key Features and Specifications

When evaluating a subwoofer like the DB Technologies SUB 618, understanding its key features and specifications is crucial. These details provide insight into its performance capabilities and suitability for different applications. Let's take a closer look at what the SUB 618 brings to the table.

Components

At the heart of the SUB 618 is its 18-inch woofer. This large driver is responsible for producing the low-frequency sounds that give your music or sound system its punch. The woofer is designed to handle high power levels and deliver deep, resonant bass. The choice of an 18-inch woofer is significant because it allows the SUB 618 to move a large volume of air, resulting in a more powerful and impactful bass response compared to smaller subwoofers.

Amplifier

The SUB 618 is equipped with a Class D amplifier, which is known for its efficiency and power output. Class D amplifiers are able to deliver a high amount of power while generating relatively little heat, making them ideal for use in subwoofers. The amplifier in the SUB 618 provides up to 600W RMS, ensuring that the woofer has enough power to produce loud and clear bass even at high volumes. The efficiency of the Class D amplifier also contributes to the subwoofer's overall portability, as it reduces the need for large and heavy heat sinks.

Frequency Response

The frequency response of the SUB 618 ranges from 33 Hz to 120 Hz. This means that it can reproduce frequencies as low as 33 Hz, which is well within the range of deep bass notes. The upper limit of 120 Hz allows the SUB 618 to blend seamlessly with other speakers in your sound system, ensuring a smooth transition from the low frequencies to the mid and high frequencies. The wide frequency response makes the SUB 618 suitable for a variety of music genres and applications.

Maximum SPL

The SUB 618 is capable of producing a maximum sound pressure level (SPL) of 133 dB. This is a measure of how loud the subwoofer can get, and a high SPL rating indicates that the SUB 618 can deliver powerful and impactful bass even in large venues. The high SPL also ensures that the bass can be felt as well as heard, creating a more immersive and engaging listening experience.

Crossover

The SUB 618 features a built-in crossover, which allows you to adjust the frequency at which the subwoofer starts to reproduce sound. This is important for integrating the SUB 618 with other speakers in your sound system. By adjusting the crossover frequency, you can ensure that the subwoofer is only reproducing the low frequencies, while the other speakers handle the mid and high frequencies. This results in a more balanced and cohesive sound system.

Enclosure

The enclosure of the SUB 618 is made of high-quality plywood, which is known for its strength and durability. The wooden cabinet provides excellent acoustic properties, helping to enhance the subwoofer's sound quality. The enclosure is also designed to be portable, with integrated handles that make it easy to carry and set up. The compact size of the SUB 618 allows it to fit into tight spaces, making it suitable for a variety of venues.

Connectivity

The SUB 618 offers a variety of connectivity options, including XLR inputs and outputs. This allows you to easily connect the subwoofer to other audio equipment, such as mixers, amplifiers, and speakers. The XLR connectors ensure a reliable and high-quality audio signal, minimizing the risk of noise or interference. The SUB 618 also features a built-in phase switch, which allows you to adjust the phase of the subwoofer to match the phase of the other speakers in your sound system. This can help to improve the overall sound quality and clarity.
