Connecting Your Loudspeakers

It is critical for proper performance that both speakers (left and right) be connect- ed in proper phase. Note that one terminal on each speaker (the +) is colored red and the other (the -) is colored black. Please make certain that you connect the red (+) terminal on each speaker to the red (+) terminal of its channel on your ampliﬁer or receiver, and the black (-) terminal to the black (-) terminal. It is essential that both speakers be connected in the same way to the ampliﬁer (in phase). If you experience a great lack of bass, it is likely that one speaker is out of phase with the other.

Usually if distortion is heard when the speakers are being driven at loud levels, it is caused by driving (turning up) the ampliﬁer too loud and not driving the speakers with more power than they can handle. Remember, most ampliﬁers put out their full rated power well before the volume con- trol is turned all the way up! If your speakers distort when you play them loud, turn down the ampliﬁer or get a bigger one.

“Spiking” Your Loudspeakers

An optional “spiking” kit has been provided should you desire to “spike” your loudspeakers. “Spiking” your loudspeakers will provide greater stability when plac- ing your loudspeakers on carpeting and will also, according to many experts, result in an overall improvement in sonic performance. Care should be taken when using spikes as they may cause damage to wooden or other ﬂoors which are susceptible to being scratched. Deﬁnitive Technology is speciﬁcally not responsible for damage which may result from the use of spikes.

The spike kit contains 4 spikes. To install,unscrew the plastic guides on the bot- toms of the speakers. Then screw the 4 spikes into the T nuts. Then (preferably with the help of another person) lift the speaker upright and lower it down to its exact desired position on the ﬂoor. You must lower the speaker to the exact position you want because once the spikes are in place you cannot move the speakers sideways on the rug or ﬂoor – this may damage the ﬂoor or the speakers. Next, adjust the spikes so the speaker sits solidly (and does not rock).

Please note that you can adjust the feet or spikes to tilt the speakers back (front to back approximately 1/2” to 1” highter than rear) for even better sound.

Speaker Break-In

Your BP 8Bs should sound good right out of the box; however, an extended break-in period of 20-40 hours or more of fairly loud playing is required to reach full performance capability. Break-in allows the suspensions to work in and results in fuller bass, a more open “blossoming” midrange and smoother high frequency reproduction.

BP 8B specifications

The Definitive Technology BP 8B is a floor-standing speaker that has carved a niche for itself among audiophiles and casual listeners alike. Renowned for its innovative design and advanced technologies, the BP 8B delivers an immersive audio experience, making it an excellent choice for both home theater systems and music playback.

One of the standout features of the BP 8B is its bipolar speaker design. This unique configuration allows the speaker to produce sound from both the front and rear, creating a wide soundstage and a more immersive listening experience. This design helps in scattering sound waves throughout the room, making it feel as if you're surrounded by the music or movie audio, rather than just hearing it from a single point.

The BP 8B is equipped with a 1-inch aluminum dome tweeter that ensures high-frequency sounds are crisp and clear. This tweeter is paired with a 5.25-inch midrange driver, which is tailored to reproduce vocals and instrumental details with precision. The bass is handled by a powerful 8-inch bass driver, which delivers deep, resonant low frequencies that add richness to any audio track. Together, these drivers work to produce a balanced sound that covers a wide frequency range.

Definitive Technology has integrated its patented PowerField technology into the BP 8B, enhancing the performance of the low-frequency drivers. This technology utilizes an innovative ported design that minimizes distortion while maximizing output, ensuring that bass notes are not only impactful but also clean.

The build quality of the BP 8B contributes to its sound performance as well. Encased in a sleek, stylish cabinet, these speakers are designed to reduce unwanted vibrations, allowing for clearer sound reproduction. The cabinet is also carefully tuned to enhance the overall audio experience, ensuring that all frequencies are represented accurately.

Connectivity is made simple with the BP 8B, which features speaker wire terminals that allow for easy connection to any home audio system. It is compatible with a variety of amplifiers and receivers, making it versatile in various setups.

In conclusion, the Definitive Technology BP 8B stands out due to its bipolar design, high-grade components, and thoughtful engineering. Whether you're watching a blockbuster movie or listening to your favorite album, the BP 8B promises to elevate your sound experience with precision and power.
