Polk Audio RTi A9 Black High-Performance Floorstanding Loudspeaker, Model RTIA9BK
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 for long listening sessions yet detailed
and revealing. 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.
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
