Subwoofers anchoring a home theater provide the rumble and visceral impact needed to get you into action. However, many subwoofers are large, with questionable construction that causes excessive cabinet vibrations.
Double-opposition subwoofers alleviate or eliminate many problems normally associated with large subwoofers using physics and have an eye for maintaining a small overall footprint. Cabinet Vibration Conventional subwoofer boxes absorb the feedback wave from the subwoofer driver. Therefore, manufacturers are trying to make this cabinet as thick and heavy as possible using mass to eliminate unwanted vibrations and resonances.
Dual-opposition designs considerably reduce this phenomenon by canceling vibrations, with residual bass energy production through the pilot cones rather than being stuck inside the cabinet. The result also includes almost total elimination of low frequency ground transfer, keeping the sound very clean. Efficiency Dual-opposition designs under their dual conductor boards are intrinsically more efficient. This means that for every power watt of the amplifier, more sound is produced than with most other models. This increase in efficiency results in greater sensitivity to low-level signals, which creates a more detailed and responsive sound. For this reason, double opposition designs should not use massive amplification to propel the subwoofer drivers forward as in conventional designs.

Any other design using dual subwoofer drivers should place them in front of the subwoofer housing, called the baffle. This automatically increases the fingerprint of the speaker. Double opposite designs only need to be as large as necessary for a single conductor, the second conductor directly opposite the first one on the other side of the cabinet. Area Bass is produced by pressurization of air. This is caused by the outward movement of the subwoofer driver, exciting the air around it. Double-opposed subwoofers by doubling the surface of the conductor or double cone area effectively the bass output. This has the effect of using two subwoofers, co-located in a single enclosure.
To understand the benefits of dual woofer speakers for a stereo system, it is important to understand how speakers work. Speakers emit sounds by vibrating and pushing the sound waves of their cones. The finer and tighter these cones are, more precisely, they can reproduce the sound. Large cones push more air and thus create more sound waves, giving them an advantage of producing a higher volume.
Although the quality of engineering, design and price all affect the way each speaker accomplishes, small speakers tend to be tighter and thus provide a greater frequency response. Area To compensate for the surface loss that comes with a tight, small diaphragm speaker, double woofer systems double the enclosure surface by having twice as many cones. Although two 8-inch speakers have less than a third of the surface of a single 15-inch woofer (and thus, less the low-frequency response capability), the dual woofer alignment addresses the volume problem Low-end that can afflict smaller diaphragm speaker.
Dispersion Dual woofer speakers are especially used in a center channel speaker help to disperse low frequencies throughout the room. Traditional mono-woofer speakers do not disperse sound as effectively and can lead to uneven levels and sound qualities around the room, with “sweet spots” in some areas. Although two woofers will not eliminate the sweet-spot phenomenon, they can open it to larger areas of the room.
