If Speaker Wire Connections Cause the Subwoofer to Hum

Certain receivers use speaker grounding circuits that may be incompatible with external powered audio products, such as powered subwoofers. When speaker wire is used instead of line level cables, this incompatibility can result in an audible hum when the receiver is turned off or switched to a different speaker channel.

If this should happen with your Boston Acoustics subwoofer, you will need to make a ground cable and connect it to either RCA line input on the subwoofer and any unused RCA line input or output on your receiver (see diagram). The proper ground cable for this application should consist of two male RCA plugs that have their negative outside terminals (or "sleeve") connected to each other by any length of single conductor copper cable. The inside positive (or "pin") terminals

should not be wired in either plug.

If you do not wish to make your own grounding cable, please contact the Boston Acoustics Customer Service Department directly (see below) and we will promptly ship one to you of suitable length at no charge.

PV900, PV700 specifications

Boston Acoustics is known for its commitment to delivering high-quality audio products, and the PV900 and PV700 models are no exception. These speakers represent a blend of innovative technology and exceptional sound quality, ideal for both casual listeners and audiophiles alike.

The Boston Acoustics PV900 is a powerful floor-standing speaker that stands out due to its dynamic sound performance and elegant design. Featuring a dual 8-inch bass driver, the PV900 delivers deep, richlow frequencies, providing an immersive listening experience. This model includes a high-efficiency 1-inch tweeter, ensuring crisp highs that balance out the deeper tones, making it suitable for various music genres and movie sounds.

One of the main features of the PV900 is its use of proprietary BassTrac technology. This technology minimizes distortion during playback, allowing for clean and accurate sound reproduction, even at high volumes. The speaker's cabinet is constructed with a rigid and well-damped enclosure, which further enhances sound clarity and reduces unwanted resonance. The PV900 is also compatible with a range of receivers and amplifiers, making it an adaptable choice for any home theater system.

The PV700, on the other hand, is a compact bookshelf speaker that doesn't compromise on sound quality despite its smaller size. It is equipped with a single 6.5-inch woofer and the same high-efficiency 1-inch tweeter as the PV900, providing a well-rounded audio experience that can effectively fill a room. The PV700’s smaller footprint makes it particularly appealing for users with limited space, while still offering impressive sound performance.

Both the PV900 and PV700 feature Boston Acoustics’ advanced driver technology, which ensures clear and precise sound reproduction across the frequency spectrum. This results in a more natural listening experience, with excellent vocal clarity and instrument separation. The aesthetic design of both models also complements modern home decor, with a sleek finish and elegant lines.

In summary, the Boston Acoustics PV900 and PV700 are exemplary models that showcase the brand's dedication to quality sound and innovation. With features such as BassTrac technology, well-constructed enclosures, and high-efficiency drivers, they cater to audio enthusiasts looking for superior performance in their home audio systems. Whether you're enjoying music or watching films, these speakers promise an enriching auditory experience.
