Placement or Positioning, Wiring and Connections

PLACEMENT OR POSITIONING

Your new subwoofer will work well in a variety of locations. However, placement in your listening room will affect its performance. Since the wavelengths of sound reproduced by your subwoofer are large compared to its size, those sounds are omni-directional in nature. This means that locating your subwoofer in relation to your left and right main speakers will not affect the directional cues which they provide.

Because the sounds you hear are a combination of direct sound from the speaker and reflected sound from the walls, ceiling, and floor of your listening room, placement of the subwoofer in relation to room boundaries changes the balance of what you hear at low frequencies. In that low frequency range, the dimensions of most rooms are comparable to the wavelengths of those sounds. As sound propagates and reflects in the room, “standing waves” are created at frequencies where the wavelength of sound or multiples of the wavelength are equal to one of the dimensions of the room. At your listening position, these standing wave patterns of reflected sound add together in and out of phase causing large variations in the response that you hear.

As a general rule, locating your subwoofer near the corner of the room will increase its overall output, but will excite more standing waves in the room and may result in a more uneven response. Locating your subwoofer along a wall will usually mean less acoustic output but a somewhat smoother response. A middle of the room location would suggest the smoothest response with the least output capability. Of course, any location will be a compromise between acoustic performance and the aesthetic blend of the subwoofer enclosure with the decor and furnishings of your room. Don’t be afraid to experiment with the location of your subwoofer in your room for the best results at your listening position. As with any other listening test, use program material that you are familiar with that has substantial bass content.

WIRING AND CONNECTIONS

Turn off all power to your subwoofer and other equipment before making any connections.

Installation using speaker level inputs

A) For amplifiers with one set of speaker connections.

If a preamplifier output connection is not available on your amplifier or receiver, your subwoofer can be connected using your equipment’s speaker outputs. These connections are made using commonly available 18 or 16 gauge lamp cord or speaker hook-up wire. Observe correct polarity by connecting red(+) to red(+) and black(-) to black(-) for both left and right channels. Connect your amplifiers speaker output terminals to the subwoofer’s speaker level input terminals as well as to your main stereo speakers according to Figure B.

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.
