Polk's trademark open,boxless sound.
I upgraded these to"i"status by changing the tweeter to the newer model.The only difference between the 55 and 55i is the tweeter and blue colored woofers according to Polk(see my review of the 55i)I LOVE these!!

"...the RT55s are a lot of fun to listen to... very spacious and airy, and provide a lot of 'bang for the buck."
Vacuum Tube Valley, Issue 12, Summer 1999
"Our panel agreed they sounded big, dynamic, and smooth...They possesed good resolution and a sense of coherency; at the same time they were very smooth and wl-behaved... Polk Audio's RT55 are a great value... we liked the level of sonic refinement provided by the RT55s at this price point."
