SOLID BUILD,GREAT STYLE,OH...GREAT SOUND !
I DIDN'T GET THEM SOONER!
GREAT BUILD QUALITY,I PLACED THIS ON TOP OF MY POLK TOWERS TO DEMO THEM,THE SOUND,IMAGING,AND POWER WERE IMPRESSIVE,ONLY MINOR DIFFERENCE IN SOUND AND ONLY WHEN I CRANKED THEM TO A HIGHER SOUND db LEVEL! THESE ATRIUM'S # 55'S HAVE GREAT IMAGE,TONE & GOOD BASS OUTPUT! A STEAL CONSIDERING THE PRICE PAID!THESE FILL MY BACKYARD WITH SOUND QUALITY THAT RIVALS A HOME THEATER!

A quality full sound in a relatively small enclosure.
They were not free.
Bought the Atrium 55's to compliment the 45's I already have out back. I was looking for a speaker that had a little more bass then the 45's could produce, and found it in these speakers. I compared them to the Bose 251 and was much more impressed with the Polk speakers sound. I give them 5 stars. You won't be disapointed.

Made in China
Now that is a pair of speaks! Installed in rear of my '92 Volvo, the flexibility of swivel can created either an awesome sounding inside or use the swivel/open the trunk for a tailgate sounding like no other. Kudos, you can't go wrong.

Crisp, clear sound. Easy of installation and directional mounts
None- With the proper power running these babies you will be blown away
Unbelievable sound quality. I'm pushing them with an older adcom 555 amp through an older Yamaha 1080. Using a Niles outdoor volume control out on my back deck. Seperation and sound is better than I could have ever expected from an outdoor speaker

Imaging and overall sound is excellent considering their size.
None - they are exceptional for 'outdoor' speakers.
For their size, and the $ paid, these are excellent speakers. I listened to 4 or 5 other wall mounted/outdoor models - including the Atrium 45s, and these were clearly the best. These are indoor in my new sunroom mounted in the top corners, powered by a vintage 70's Marantz 2235B receiver. The combination sounds great!

Durable, easy to mount, great terminal connections.
Made in CHINA like everything else...
A perfect rear channel match for the RC85i. Spacial separation and imaging is excellent. I've replaced all my floor standing speakers with in wall and corner mounted and the sound is terrific! Now I have room to walk around the family room. Home theater ROCKS with all POLK speakers!

Clear crisp sound. By far the best for the money!
None to report...
I am a professional Multi Media installer and have installed some of the worlds best sound systems. I recently installed a set of Polk Atrium 55 speakers around a clients pool/patio, I was under a budjet, didn't want to compromise quality. I was plesantly surpirsed how crisp , clear & responsive they were! Thanks Polk Audio ANOTHER JOB WELL DONE!

sounded good when they worked

Could you be a bit more specific on what failed? We can then try to find a solution.
