Polk Audio Compact Indoor/Outdoor Speaker Black Pair
The Atrium4 is the smallest, most compact member of the latest generation of Atrium all-weather outdoor loudspeakers. Ideal for tight spaces, the Atrium4 will nonetheless prove more than capable of filling outdoor spaces with the legendary Polk sound.

Big Fidelity, Small Speaker

The compact Atrium4 loudspeaker produces high fidelity sound quality anywhere you want great sound. It's small size makes it ideal for tight, out-of-way installations. By the pool, around the kitchen, tucked away in the family den or filling the backyard with great sound. Like our bigger Atriums, the Atrium4 is built rugged to deliver years of great performance fall, winter, spring and summer.

Atrium4 Features:

  • Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system.
  • 4 1/2-inch (11.43cm) long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
  • 3/4-inch (19mm) anodized aluminum dome tweeter with neodymium magnet for better power handling and smoother response.
  • Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. You want to fill a large open outdoor space with big, full-range sound, The new Atrium Series has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.
  • Polk all-weather certified, Atrium Series speakers exceed baseline industrial and military specifications for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion, Mil-Std 883 Method 1009.8 for salt and corrosion.) Certification means Atrium speakers can effortlessly withstand the worst Mother Nature can dish out, whether its extreme temps or heavy rains. With certification like this, your kitchen or bathroom installation is a cakewalk for Polk all-weather speakers.
  • Speed-Lock™ mounting system, for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means fewer parts to "juggle." Simply mount the bracket and click the speaker into place. Aim it and tighten it down, and you're finished! Outdoor convenience, indoor sound quality!
  • Durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not "an outdoor speaker"), and survives years of seasonal changes, for truly great sound, no matter what the weather.
  • Patented Dynamic Balance® and Klippel optimization technologies ensure the perfect material performance, eliminating driver and tweeter "artifacts" for more realistic sound reproduction at high and low volume levels.
  • Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
  • Gold-plated 5-way binding posts for the most secure, dependable hookups.
  • Available in durable, weatherproof black or white paintable finishes.
  • All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry's most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

4 out of 5 eggsDecent Speakers

Pros: Good Sound, Good Mounting

Cons: Weak in the Bass end

Other Thoughts: I have a set of these in my bathroom. I have 6 sets of the Polk Audio Monitor 30 throughout my apartment. The Monitor 30 have better bass than these Atrium 4. The quality of the sound from the Atrium 4 is good but the bass end is a weak. I just wanted a set of speakers to handle the moisture in the bathroom, so far so good. I rated them 4 eggs because of the weak bass end and i think they are a little over priced.

5 out of 5 eggsGood Outdoor Speakers

Pros: Excellent clarity - I have no distortion problems whatsoever. Mounting brackets provide for multiple mounting options and angels. Speed-Lock Mounting System really simplifies the mounting and adjustment process.

Cons: Minimal bass response, but that is to be expected from a speaker this size - still sound good. Frivolous label on grill face leaves adhesive that must be cleaned off after label is removed.

Other Thoughts: Have these mounted outside on lower level of two level deck. The mounting bracket allows for these to be mounted to bottom of upper deck support beam, angled downwards at 45 degrees.
