Amazon.com Product Description
Polk's Atrium 45p speakers offer versatility, power, and style all in one. Each speaker's sealed, black stainless-steel enclosure houses a 4.5-inch long-throw polymer cone driver with a butyl rubber suspension for pumping out amazing bass, while the 0.75-inch soft dome tweeter--which includes a neodymium magnet--broadly distributes high frequencies to cover a large area with high-fidelity sound.

The speaker's aluminum grille boasts an open area of 55 percent for superior sound quality, which is aided by the sculpted front baffle and rounded enclosure that minimizes diffraction (sound that's reflecting off of hard edges) for more open and lifelike imaging. In addition, a built-in bracket facilitates several mounting options and full 90-degree rotation, letting you aim the speakers to several points in the room to enjoy the best possible sound.

But perhaps the 45p speakers' most attractive feature is that they're self-powered, which allows you to create an instant sound system simply by connecting a CD player, MP3 player, or other audio source directly to the speakers via their coaxial line-level inputs. As an alternative, you can connect them to an amplifier or receiver using the set's gold-plated five-way speaker-level binding posts. Whichever method you choose, you can add Polk-quality, room-filling stereo sound quickly and conveniently almost anywhere.

The speakers, which offer a frequency response of 60 Hz to 20 kHz, measure 6.25 by 9.5 by 7.62 inches (W x H x D) each and are backed by a five-year warranty on parts and labor.

Customer Reviews

Decent speakers, but there are better ones
I purchased these speakers for one of my clients, and they are decent speakers. However, for the some money, you can a lot better speakers, such as the Advent AV570 speakers. The Polk speakers include one powered speaker and one passive speaker. They have a decent design, but look more like outdoor speakers than indoor speakers. The sound of these speakers is very crisp, but the bass is lacking - the range is not as wide as they make it out to be.

We originally chose this pair of speakers because they were more attractive than the Advent speakers. However, they ended up being not so pretty - the picture is somewhat misleading. If this matches your home set-up/color scheme, etc., then go for it; otherwise, you can do a lot better with the money.
