Tower Loudspeaker: The Definitive Technology BP9040 tower speaker is
the answer for remarkable, immersive, room-filling sound so you can experience
every detail of your home theater soundtrack. Its patented Forward Focused
Bipolar Array (FFBP) will expand your room's entire soundstage for an enveloping
sound. An aluminum dome tweeter, high-performance midrange/midbass drivers, and
an integrated powered subwoofer with Intelligent Bass Control let you hear and
feel every note as the artist intended.
Forward-Focused Bipolar Array (FFBP): The Definitive
Technology BP9040 tower speaker utilizes powerful, Forward-Focused Bipolar (FFBP)
speaker array for wide and immersive sound dispersion. Forward Focused Bipolar (FFBP)
Array offers the ultimate balance between room-filling sound and a precise
center image, while giving you total placement flexibility. The FFBP array
consists of a 1" aluminum dome tweeter and two 4.5" midrange/midbass cone
woofers on the front and a single 1" aluminum dome tweeter and one 4.5" midrange driver on the back. By radiating
sound both forward and rearward, the speaker produces sound as it is in real
life, with improved pinpoint localization of soloists, greater placement
flexibility, and superior intelligibility.
Aluminum Dome Tweeters: The BP9040 tower loudspeaker features
two 1" aluminum dome tweeters (one on front/one of back) for crystal clear highs that bring the most
demanding audio soundtracks to life. The Definitive Technology tweeters are
designed to play higher in frequency than what is heard by the human ear,
creating an authentic reproduction of sound as the artist intends in the studio
or concert hall.
BDSS (2nd Gen) Drivers: The Definitive Technology BP9040 employs
midrange/midbass cone woofers (two on front/one on back) with patented Balanced Double Surround System (BDSS)
technology (2nd generation). BDSS technology improves driver excursion which results in the
selected driver producing bass output usually associated with a larger driver,
while retaining the improved dispersion and midrange definition of a smaller
Integrated Powered Subwoofer: The BP9040 contains a integrated powered
subwoofer that consists of a side-firing 8" woofer and 300 watt amplifier designed to
extend the frequency response and dynamic range of the tower speaker.
The best loudspeaker is one that reproduces balance between the highest highs
down to deepest lows as accurately as possible. The integrated powered subwoofer
offers deeper, more impactful bass from the tower speaker without the
need to add a separate powered sub. The benefits of a built-in subwoofer include
- Eliminates the need for a separate subwoofer that takes up additional
- More bass output from two subwoofers, compared to one.
- Two subwoofers reduce standing wave room resonances and dead zones.
- The subwoofers are perfectly integrated and blended with the mids and
highs, eliminating the crossover and phase controls of a separate subwoofer.
Intelligent Bass Control: Intelligent Bass Control is Definitive
Technology's latest advancement that offers enhanced bass while maintaining
overall mid-range tonal balance. Intelligent Bass Control gives you the ability
to modulate deep bass up or down in level while simultaneously maintaining
optimal mid-range clarity regardless of where the bass control is set. Simply
rotate the dial on the back of the loudspeaker to your preferred bass setting
and the speaker will do the rest. Definitive Technology recommends starting at
the mid-point and then adjust to your preference from there.
Dual Passive Radiators: Definitive Technology has paired its
integrated powered subwoofer system with two opposite side-firing 8" passive
radiators for even bigger, deeper, louder bass that you can hear and feel.
Acoustically Transparent, Resonance-Free Cabinet: The Definitive Technology
BP9040 uses a resonance-free, one-piece cabinet for high performance, distortion-free sound. The speaker
cabinet's maximum rigidity with strategically placed bracing improves imaging
while reducing resonance, further reinforcing the speaker's clean and powerful
The BP9040 loudspeaker's cabinet is wrapped in an acoustically transparent cloth
grille for unaltered sound. Thanks to the speaker's acoustically transparent grille, you'll enjoy the
subtle elegance of the speaker design without having to remove a speaker grille
to enjoy natural, uncolored sound. On the top of the cabinet is a brushed
aluminum, acoustically-treated magnetic plate that finishes off the speaker
Speaker & Line Level Inputs: The Definitive Technology
BP9040 tower loudspeaker is fitted with both speaker-level (binding post) and
line-level (LFE/mono-RCA) inputs.
- Binding Post Terminals:
The speaker terminals are 5-way binding posts that will accommodate spade
connectors, single or dual banana plugs, pin-connectors, and bare wire up to
10 gauge. By connecting the tower speaker's binding post terminals to your AV
receiver's front speaker terminal outputs, the BP9040's internal crossover
network distributes all frequencies to their intended drivers, and the
integrated subwoofer works harmoniously with the mid-range array. In your AV
receiver's menu, set the Front speakers to "Large" and Subwoofer to "No".
- LFE/mono-RCA Input: For those you demand greater
customization, the BP9040 also features an LFE/mono-RCA input. In this
setup, your AV receiver's front speaker outputs still connect to the
BP9040's binding post speaker terminals, but also requires that the AV
receiver's LFE/mono-RCA output to be connected to the tower speaker's
LFE/mono-RCA input. This type of setup gives you the ability to control the
amount of low frequencies (those below the crossover point set in your
receiver) sent to the integrated subwoofer. You will need to set front
speakers to "Small", subwoofer to "Yes", and the crossover point in your AV
receiver to 80Hz or below to avoid disturbing the delicate blending between
the subwoofer and midrange. In addition, careful balance between the
subwoofer output level of your receiver and the bass control on the back of
your speaker should be considered (Definitive Technology recommends starting
with the bass control at 12 o'clock).
Note: Definitive Technology recommends that you do not use
your receiver's auto setup functions, as they can be ineffective in setting
up and adjusting speakers with integrated powered subwoofers. Configure
tower speaker into your home theater system using your AV receiver's manual
Cast Aluminum Base w/ Interchangeable Feet: The BP9040 tower
loudspeaker is supported by a sturdy, cast aluminum base. The cast aluminum base's wide
footprint increases overall stability of the tower speaker, while the addition
of spikes or floor glides help keep your speakers firmly in place whether on
carpet or other solid floor surfaces like hardwood or tile. The floor glides add
approximately 0.4375" to the overall height of the tower speaker, while the
spike feet add approximately 1" to the overall height of the speaker.
Note: The tower speaker must be used with the cast aluminum base for
Placement: The BP9040 tower speaker offers bipolar sound, meaning they
will reflect sound off the back and side walls to create an incredibly broad and
engaging soundstage no matter where you sit. The BP9040 tower
loudspeaker is very flexible in terms of positioning and placement. To optimize
performance, please follow these simple placement guidelines -
AC Power: Because the BP9040 features a built-in powered
subwoofer, you will need to connect the tower speaker to an AC
outlet. The tower speaker's built-in amplifier will automatically turn-on
once it's receiving an active signal from your AV receiver, and will
automatically turn off after 20 minutes of no active signal.
Front-Panel LED: There is a front-panel LED "D" logo which
illuminates when the BP9040's built-in amplifier is on, and turns off when the
built-in amp is in standby mode. The LED "D" logo can be deactivated entirely.
Optional Dolby Atmos Elevation Module: The BP9040 features an
integrated, hidden connector port that fits Definitive Technology's
A90 Dolby Atmos elevation speaker module (sold separately) seamlessly.
Simply remove the magnetically-sealed, acoustically treated aluminum top panel
from the BP9040 tower speaker and firmly align and place the A90 elevation
speaker module within the top of the tower speaker to hear and feel Dolby
Atmos multi-dimensional sound. There are dedicated binding post terminals
(labeled "Height") to connect the "Height" channels of your AV receiver to the
BP9040.You will also need a Dolby Atmos-enabled
receiver and Dolby Atmos-encoded source material.
BP9000 Series: The BP9040 is part of Definitive Technology's
BP9000 series line-up of speakers. Definitive Technology's BP9000 series
loudspeakers is its 4th generation of bipolar tower speakers, matching center
channels, surrounds, and a height speaker module, designed to offer true,
