The SR-8040HD is built to the same high performance standards as Definitiveʼs main left and right front speakers and includes features like high-definition second generation patented BDSS bass/midrange drivers with butyl rubber surrounds, wide-dispersion pure aluminum dome tweeters, complex crossover networks and rock-solid cabinet construction. It can be mounted to a wall with the integrated keyhole plate or it can be placed atop a shelf or after-market stand. However you use the SR-8040BP youʼll enjoy superior surround sound realism.

The Bipolar Advantage
Definitiveʼs SR-8040HD is a bipolar system containing two complete full-range speaker systems, one on each side of the cabinet. Bipolar radiation spreads the surround signals evenly throughout your room for a more enveloping sense of you-are-there realism than could be achieved with conventional forward-firing speakers.

The SR-8040HD is a full-range, extremely linear, low-distortion system which is timbre-matched to blend perfectly with all Definitive BP series speakers as well as other high-quality speaker systems. The SR-8040HD wide dynamic range, high-definition sound quality and its bipolar radiation pattern results in total immersion in the musical event or movie soundstage.

Bipolar Surrounds are Easy to Use
Definitive's bipolar surrounds are designed for easy and unobtrusive placement in your room. Easy-to-use mounting plates are included for wall mounting. Definitive's BP surround speakers may be located on the sides or rear of the room (or both as in 6.1 and 7.1 channel installations) with excellent results.

Patented Technology Delivers High Definition and Wide Dispersion
Dispersing the surround channel sound evenly over a broad area of the room is vital for creating the enveloping youʼre-in-the-action experience movie directors intend for you to experience. Weʼve engineered the SR models with our latest generation ultra-high definition midrange drivers that set new standards for wide dispersion and clean, accurate reproduction.

The drivers used in the SR-8040BP are 3-1/2" second generation BDSS drivers. BDSS is Definitiveʼs patented Balanced Double Surround System technology that supports the speaker cone at both the inner and outer edges allowing longer, more linear excursion for greater clarity and finely textured inner detail. A new patent pending Linear Response Waveguide™ smoothes off-axis frequency response and disperses sound over a wider area for crystal clear intelligibility and life-like envelopment for every listener in the room. The tweeters are pure aluminum domes, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess.

The Proof is in the Listening
Now that youʼre thoroughly impressed with the technology and passion weʼve poured into the SR-8040BP it is time to find a stocking dealer near you to audition this remarkable achievement of art and science.

• More versatile mounting options than any other loudspeaker, with a modular, removable, switch-around base and built-in keyhole slots.
• Mounting Options: 1. Angled wall mount 2. Corner mount 3. Horizontal wall mount 4. Vertical wall mount 5. Shelf mount 6. Horizontal shelf mount 7. Use an optional articulating bracket (such as OmniMount 10.0 not included) for ceiling or swiveled wall use.
• (If you can think of any more, please let us know!)
• The OWM Series is timbre-matched to other Polk loudspeakers, so you can mix and match them to build or add to existing systems.
• Dynamic Balance® composite cone drivers are lightweight and stiff, with excellent damping qualities, for high efficiency, excellent mid-bass and low distortion even at extreme volume levels.
• Patented Dynamic Balance materials technology tunes out cone resonances before they become a part of the finished product, so you only hear the most realistic, natural audio reproduction.
• Durable, high performance fabric dome tweeters deliver clear and detailed high frequency response and excellent imaging.
• Capacitive Coupling Technology (CCT), an advanced signal-blocking technology that overcomes the usual limitations of small-enclosure loudspeakers (slim dynamics and no low frequency response), delivers extended dynamic range and enhancing deep bass response for clear, detailed musicality with little or no coloration.
• Glass-filled ABS enclosure is super-dense and acoustically inert, ensuring an extremely clean and low coloration midrange response.
• Paintable white finish blends into any decor.
• 5-way gold-plated binding posts, for the best connections, are easily accessible no matter how you mount the speaker.
