B)For use with A/V preamps and receivers that have 5.1 channel line level outputs.

If your preamplifier or receiver has a single “subwoofer” output or “LFE” output, connect a shielded cable from the preamplifier output to either one of the subwoofer line level inputs. Refer to Figure E.

UNPACKAGING/PRE-INSTALLATION INSTRUCTIONS

Unpack your new subwoofer carefully, keeping the carton and packing material for future use. Check the condition of your unit, reporting any damage which may have occurred in transit to your dealer or shipping company.

GLOSSARY

The following list of terms with their definitions is offered as a help in understanding the set-up and operation of your subwoofer.

Crossover (xover) - an electrical filter with lo-pass or hi-pass characteristics that divides the frequency range into bands of low, middle, or high frequencies to match the capabilities of specialized loudspeakers like subwoofers that are only effective at reproducing limited frequency ranges. The crossover frequency is the frequency where the filter begins to attenuate or reduce the level of the signal.

Full range - refers to signals which cover the entire audio frequency span from 20 Hz to 20 kHz.

Hi-pass - a type of filter circuit that allows high frequencies to pass, while reducing the level of low frequencies with the transition from high to low occurring at the crossover frequency. The rate of reduction of the signal is called the attenuation rate or slope and is measured in decibels (dB) over a change in frequency of one octave, which is a doubling or halving of frequency.

Impedance - the resistance to the flow of current in an alternating current circuit (such as with music). Line level circuits are typically a high impedance of several thousand ohms, while speaker level circuits are usually a low impedance of a few ohms.

Line level - the type of signal produced at the outputs of preamplifiers, tape decks, CD players, etc., with a typical value of a volt or less in a high impedance circuit. Sometimes called low level signals, they are routed using shielded cables which are usually terminated with RCA phono connectors.

Lo-pass - a type of filter circuit that allows low frequencies to pass, while reducing the level of high frequencies with the transition from low to high occurring at the crossover frequency. The rate of reduction is called the attenuation rate or slope and is measured in decibels (dB) over a change in frequency of one octave, which is a doubling or halving of frequency.

Speaker level - the type of signal produced at the outputs of power amplifiers that may be many volts in a low impedance circuit. Sometimes called high level signals, they are routed using two conductor unshielded wire of 18 gauge or larger. Connections are usually made with stripped ends of wire gripped in spring loaded terminals.

TB2 specifications

The DCM Speakers TB2 is a remarkable addition to the realm of audio equipment, bringing exceptional sound quality and innovative design to music enthusiasts and home theater aficionados alike. Renowned for their exceptional engineering and commitment to providing high fidelity sound, DCM offers a speaker that is deeply rooted in the quest for audio excellence.

One of the standout features of the DCM TB2 is its driver configuration. The speaker features a 6.5-inch polypropylene woofer, designed to deliver powerful bass response, ensuring that low frequencies are bold without overwhelming the midrange and treble elements. Accompanying the woofer is a 1-inch silk dome tweeter, which produces smooth high frequencies with a natural warmth. This combination allows for a well-rounded soundstage, suitable for various genres of music as well as movie soundtracks.

The TB2 utilizes advanced technologies to enhance its audio performance. DCM engineers have implemented a unique Time-Align technology, which ensures that sound waves from each driver reach the listener at the same time. This results in a coherent audio image, making it easier for listeners to pinpoint the location of individual instruments and vocals. Additionally, the speakers are designed with a rear-firing bass port, which enhances low-frequency output while allowing for flexible placement within a variety of room settings.

Another significant aspect of the DCM TB2 is its construction. The cabinet is crafted from high-quality materials, ensuring durability while minimizing unwanted resonance. The design is both functional and aesthetically pleasing, combining a contemporary look with classic audio principles. The compact size of the TB2 makes it a versatile option for both bookshelf and stand-alone configurations.

Moreover, the DCM TB2 is engineered for compatibility with a variety of audio systems, including home theater setups and high-fidelity stereo systems. With an impedance of 8 ohms and a sensitivity rating of 88 dB, the TB2 can be efficiently driven by various amplifiers, making it suitable for entry-level systems as well as more advanced configurations.

In conclusion, the DCM Speakers TB2 stands out for its robust engineering, advanced technologies, and harmonious sound reproduction. Offering an exceptional listening experience, it is an attractive option for anyone looking to enhance their audio experience, whether for music or movies. With timeless design and modern performance capabilities, the TB2 is poised to remain a beloved choice among audiophiles.
