A speaker for all seasons — Dual crossover networks

Polk audio has chosen the name for its new multi-purpose/outdoor speaker line carefully. Atrium evokes large, spacious chambers, lobbies, or patios — any wide, open, central location where people gather. And it?s precisely this idea of people coming together that the Atrium series tailors itself to. Whether it?s in a second room in your home — like the dining room — or out back on your deck or in your backyard, Atrium-series speakers give the places you and your friends and family gather the feel of a truly auditorium-like soundstage. The Atrium65SDI is the star of the Atrium line. A dual crossover network combined with a dual-tweeter array and dual-voice-coil mid/woofer driver mean that this mean that this speaker can either be used singly to produce stereo content, or paired with another Atrium65SDI as a single right- or left-channel speaker in a stereo pair.

Stereo from one speaker, if you like

Look to the Atrium65SDI from Polk for the ultimate in outdoor audio applications. A unique dual/single-input crossover network design gives you the ability to use the Atrium65SDI as a single speaker — delivering stereo audio to you backyard or deck — or as part of a stereo pair. Use the simple rear-mounted input switch to choose either Dual Input or Single Input for the unit. The Atrum65SDI's unique driver design makes this single-speaker stereo-audio functionality possible. The 6.5" long-throw mid/woofer driver features a dual voice-coil design, allowing for stereo mid- and low-frequency audio reproduction from a single driver. Dynamic Balance® laser-imaging-optimization enhances mid - and low-frequency performance by using laser imaging to create the right combinations of materials, driver geometry, and construction techniques to produce flat frequency response, sharp detail, transparency, and dynamic wide-range audio reproduction. Further, Dual Tweeter Array with Stereo Tweeter Aiming employs two 1.0" tweeters to achieve excellent audio imaging whether the speaker is used singly or as part of a pair.

How low can you go? Polk's PowerPort

You might not think it, but more low points are exactly what your backyard party needs. You're just a couple of beats away from a dance-party breakout on your deck thanks to the enhanced low-frequency sound reproduction offered by the Atrium65SDI's PowerPort vented enclosure. Vented systems use the sound produced at the rear side of the driver's diaphragm to increase the efficiency of the system at low frequencies by taking advantage of the resonance of ports or vents designed into the enclosure. The air mass in the cylindrical ports resonates in response to the movement of the air behind the diaphragm within the enclosure, similar to the way that the air in a glass bottle resonates when you blow air across its mouth. The Atrium65SDI?s PowerPort vented design overcomes the inherent limitations of other vented designs by using a cone structure at the port's mouth to reduce natural turbulence. Simultaneously, the vented design allows for a more modest enclosure size that won't be obtrusive in your backyard. Additionally, the PowerPort's design includes a flared "umbrella" diffuser and Bugscreen Protector that keep water and insects from entering the cabinet through the port. For total waterproofing, use the PowerPort Plug to seal the cabinet completely in extreme weather.

Outdoor concert, anyone?

Summer days and summer nights mean just one thing — parties on the deck or in the backyard. And while you might have all the company, food, beverages, and lawn games you need for a killer get-together, your party just won't be complete without the appropriate soundtrack. Now, you could continue to prop open your rear sliding glass door in the hopes that a note or two will come floating out into the back yard from the audio system in your living room, or your convert your yard into an impressive soundstage with the help of Polk's Atrium65SDI outdoor speaker pair. Not only is all of each speaker's hardware constructed of either stainless steel or brass and the grille of rustproof aluminum, but these speakers meet stringent salt, corrosion, and immersion standards, guaranteeing years of reliable performance even if installed in full exposure to the elements. Also, the white version of the Atrium65SDI can be painted to match your exterior siding or foliage.

Go ahead, judge a book by its cover

When it comes to speakers and powerful, accurate sound reproduction, what's on the outside is just as important as what's on the inside. And there's more to thePolk Atrium65SDI's cabinet than just the PowerPort vents. The Atrium65SDI's cabinet features a sculpted front baffle, rounded enclosure design, and aluminum grille that minimize diffraction for more open and lifelike audio imaging. Diffraction describes the distortion of sound resulting from reflection off of hard edges. Less diffraction means crisper, cleaner audio that's truer to the source material.

Not a sheltered speaker

We've already mentioned the Atrium65SDI's imperviousness to the elements, but we wanted to stress the point by discussing this speaker's installation potential. To sum it all up, the Atrium65SDI can be placed anywhere. Unlike many so-called "outdoor" speakers that still need to be installed in a sheltered location, the Atrium65SDI can be installed in any outdoor location. And to aid in installation, the included rustproof aluminum mounting bracket allows for multiple mounting options thanks to a full 90° rotation range, allowing you to aim the speaker for optimal backyard soundstage design.

Secure, versatile connections

The gold-plated five-way binding posts featured on the Polk Audio Atrium 65SDI are designed with wide holes for large-gauge bare-wire connections. This binding-post construction offers the most secure audio-cable connection, and is the most versatile wiring application available.
