If anyone tells you these speakers don't do music well, then maybe their expectations are worth $100,000.00 I drive my A9's with an Emotiva XPA-2, 300wpc. I can crank these things til I can't stand it, no distortion. As they break in, these speakers...

Good investment, Great for home theater, Great for music, Easy to drive, Very attractive, When driven properly has thundering bass, Articulate, Crisp, Detailed

A little harsh, or bright during break in.

mis information


For the price either these or psb image t6 or kef r series(a bit more but a jump up in quality)

the rti 7 has only one midrange driver,the a9 has 2...these are really great speakers if you have the amp to get them to sing properly..if using anything less than 200 watts you aren't getting the cream these can produce

very heavy,but that's actually a good thing as the cabinets don't resonate

A True Audiophile Speaker


Thanks to Newegg also for shipping these Fedex so they didn't get pulverized by the rough handling perpetrated so often by that other ground carrier. They arrived undamaged.

Wow, I’m really happy with my purchase. These speakers are worth every nickel I spent. I’ve owned the Polk Monitor 70’s for a couple years now and believe the 70’s are a great value but even though I tried bi-amping them and powering them with a...

None so far. Did I mention the vernier wood finish and how beautiful and glossy it is?

Rti A9


One of the speakers came with the bass port that fell off or had been knocked off. Other than that great speaker. Shipping took about 1 week to my door and for 399.00 each you really can't complain.

Great sounding speakers across the spectrum! Beautiful design.

Heavy. If that's a con.

Product Specifications

The RTi series occupies the "Better" position in Polk's "Good" (Monitor Series), "Better" (RTi Series) and "Best" (LSi Series) freestanding speaker positioning strategy. The RTi products feature all-new drivers and tweeters and striking contemporary cosmetics. All RTi models feature the latest generation Dynamic Balance drivers and tweeters. The bass/midrange drivers used throughout the RTi range use polymer/mineral composite cones. The 1-inch tweeter is a silk/polymer composite dome for smoother response and better detail than the tweeter used in the previous RTi Series. It features a neodymium magnet, low-viscosity ferro-fluid cooling and a heat sink on the back of the magnet for better power handling and reliability. All models feature Polk's patented Power Port technology that reduces turbulence at the mouth of the port. Power Port vastly reduces "chuffing" or "port noise" and provides deeper, more powerful, lower distortion bass than could be achieved with conventional ported or sealed designs of comparable size. The RTi A9's midrange driver and tweeter are housed in a sealed enclosure that is isolated from the woofer enclosure to prevent interference effects that would degrade midrange performance. The larger floor-standing model RTi A9 uses multiple long-throw 7" woofers to combine the wide dynamic range benefits of a single large woofer with the tight, punchy, accurate bass response of small woofers. Combined with Power Port Plus, these multiple woofers deliver deep high impact bass with speed and accuracy. The RTi models are magnetically shielded to allow safe placement next to televisions or video monitors. All models feature gold plated 5-way binding posts with dual inputs for bi-amplification or bi-wiring.
