Polk Audio High Performance Floorstanding Single Loudspeaker
Want third row center at a rock concert? Want home theater that will break the china? Want to make your neighbors move? If you want all of that and you want to hear the air in a flute or the bow on the strings, the RTiA9 is your speaker. It's outrageous. It's delicate. Like the finest sportscars, it's all you can handle.

Better than Being There

Don't be fooled by its great looks. Over three years in development, the RTiA Series represents the essence of the famous Polk sound – inviting, natural, lifelike audio reproduction. Why "natural" instead of "accurate?" Some speakers touted as "accurate" can be antiseptic – interesting at first but become fatiguing. There's a name for it: listener fatigue. Often it's subconscious; you'll find that as weeks pass you are listening to your system less and less. On the other hand, the RTiA's are natural sounding, engaging and comfortable, yet detailed and revealing, made for long listening sessions.

The RTiA9 is a high performance powerhouse and the ultimate manifestation of our RTiA Series. Featuring Dynamic Balance® Transducers – three 7-inch bass drivers, two 5 1/4-inch midrange drivers and a 1-inch high frequency dome tweeter – the RTiA9 will fill even the largest room with energy and excitement. With a mind blowing 500-Watt power capacity, these speakers can take everything you can give them and more. Watch high octane action movies in their full grandeur, or delight in an intimate jazz performance.

RTiA9 Features:

  • The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA9 cabinets are designed for clean, accurate sound.
  • The two 5 1/4-inch midrange drivers are housed in their own tuned internal enclosures for increased clarity and lifelike detail.
  • Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
  • Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
  • Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
  • The RTiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
  • Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
  • Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
  • PowerPort® Plus bass venting is our patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more musical, deep bass impact.
  • All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
  • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
  • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio.
  • All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry's most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

5 out of 5 eggsNOT BAD AT ALL

Pros: So, these speakers have been amazing, I am currently running them only on 65W of power to each

but will be going up to 145 this weekend

I have found them to be VERY sold and they just SOUND AMAZING

i do recommend having a BIG room for them as if you have them in a tiny room you may just go with rti 5s or 7s

Cons: none

Other Thoughts: if you have questions about anything you can email me pavlovskyrepair@gmail.com

5 out of 5 eggsmis information

Pros: 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.

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

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

5 out of 5 eggsGreat 1

Pros: AMAZING SPEAKERS!! Sound is as clear as i've ever heard. Hearing things in music and movies I haven't heard before. Just be warned these speakers are HUGE. Big and heavy. If you have the room and the coin they are worth it!

Cons: No cons except for maybe the size.

5 out of 5 eggsAMAZING

Pros: Ok, so i bought these to replace my yamaha 777 s , and boy are these amazing. By far the best speakers ive ever owned

they have amazing bass (no sub needed even thought i have 2)

the highs are amazing at 40 percent power it sounds like some one is standing in front of you and singing!

I would recommend these to ANY ONE who has the BUDGET

i did buy these off here for only 500 (they were on sale for one two days)

and it was the best 2,000 ive ever spent (bought 4)

Cons: they might be heavy for some but heavy means real wood so im not sure if thats a con or pro up to you....

Other Thoughts: GET THEM!!!

4 out of 5 eggsBeautiful speakers

Pros: Solid, well-built, beautiful speakers. Unbelievably excellent sound, but that was expected at this level of speaker. Bi-amping is even possible with the dual set of binding posts.

Cons: Packaging is not adequate to survive freight handling. Both Polk Audio and Newegg should understand this by now.
