RT25i

"Polk's new Reference Theater RT25i caught me off guard. It handled all sorts of home theater hijinks with assurance, and was cool with most of my jazz and rock CDs, too. Not only does this compact speaker pair sound great, but their genuine wood veneer looks a damn sight better than the finish on most speakers in this price class."

"The spunky little RT25i's appetite for anything from punchy big band romps to power pop jaunts was near insatiable. My evaluation pair threw a wide and spacious soundstage, yet it was easy to pluck out individual players in even the most densely packed recordings. Basically, this bad boy is a remarkably open-sounding loudspeaker."

"The original RT25 was one of my favorite little inexpensive speakers. It had marvelous clarity, really excellent bass for a speaker its size and was an excellent performer for the money. The new RT25i is a little winner too."

"Tonal balance...was outstanding...very neutral and transparent, with just about zero evidence of any of the common midrange colorations..."

The report showed the excellent capacity of RT-25i. They appreciate in the high technology of tweeter, woofer and Power Port System. Though small in size, the sound quality is clear and real. The capacity in frequency response is very high and delicate. (The preceeding is a rough synopsis of the review translated from the original Thai text. Sorry, our Thai is a little rusty.)

"It [the Polk Audio RT25i] is far superior to any speaker I've heard for less than $500/pair, and has become my favorite speaker for under $1000/pair... I've never been more impressed by an inexpensive loudspeaker."

RT35i

"…the RT35is were marvels of tonal, spatial and dynamic clarity. Not once did I lose track of the musical thread during the musicians' often highly complex interplay. This recording also allowed the RT35is' remarkably coherent midband to shine -- it's fast, incisive, terrifically textured, and throws an open soundstage with highly accurate imaging."

" Polk's new RT35i is a most impressive bookshelf loudspeaker. The few sonic shortcomings it exhibits are minor when compared to its many strengths. Polk has been on a roll the last few years, and the RT35i keeps Polk's train right on track."

"The Polk RT35i two-way, bookshelf-sized speaker is an incredible sounding speaker at a price that brings high-end sound within reach...for the incredible sound it produces, the RT35i is worth every cent."

RT15i

"...mid-range was very smooth and vocals were reproduced naturally...they image beautifully. Acting as relative point sources, I was able to obtain very natural instrument sizes with good orchestral depth, height, and width.

If you're in the market for a small bookshelf speaker, give these a listen."

f/x300i

"…a highly adaptable virtuoso performer… Judged on its own, the f/x300i is an excellent-sounding and highly versatile speaker. My estimation of this nimble little surround increased when it was used as part of an all-Polk system.

Monitor 30

"Polk's build-quality standards outpace the competition's...cabinet construction is rock solid, and the internal crossover uses high-quality parts...Ably assisted by the PSW10, the [Monitor]30 sounds like a much larger speaker...The speakers' dynamic impact and power are state of the art for a system in this price class...Clearly, the spiffy new Monitor ensemble is a worthy successor to the original models."

Monitor 40

"The Polk [Monitor 40] speaker system provides a balanced sound through dynamic balanced drivers. These drivers offer low distortion and sound that is smooth...clear and precise."
