Polk R350C – Premium Slim Center Channel Speaker for Natural Dialogue
Experience stunning vocal clarity and cinematic sound with the Polk R350C. Designed as a premium slim center channel speaker, it brings dialogue and sound effects to life with exceptional detail and balance.
Perfect for modern home theater systems, the R350C delivers Polk’s signature sound accuracy within a sleek, low-profile enclosure that complements today’s ultra-thin TVs. Whether you’re watching movies, streaming series, or listening to music, the Polk R350C ensures that every voice and sound is crystal clear.
Design & Build Quality of the Polk R350C
The Polk R350C combines minimalist design with acoustic engineering excellence. Its slim, horizontally-oriented cabinet makes it ideal for placement under flat-screen TVs or inside media consoles. Built from acoustically inert MDF, it minimizes unwanted resonances for pure, undistorted sound reproduction.
The speaker’s matte finish and magnetic grille enhance its sophisticated appearance, while the cabinet’s internal bracing ensures consistent, distortion-free performance even at high volumes. Furthermore, the R350C can be mounted vertically as left/right speakers, adding flexibility to your setup.
Polk’s design philosophy emphasizes both aesthetic harmony and acoustic performance, ensuring that the R350C sounds as stunning as it looks.
Power Output & Performance
Beneath its refined exterior, the Polk R350C houses four 4” Turbine Cone midrange drivers and one 1” Pinnacle Ring Radiator tweeter. Together, these components produce wide, natural sound dispersion and lifelike tonal balance.
The Turbine Cone drivers deliver accurate midrange frequencies — where most dialogue and instruments live — while the Pinnacle tweeter extends the high frequencies with pristine clarity and airiness. With a frequency response of 66Hz–38kHz and 89dB sensitivity, the R350C performs effortlessly across genres and formats.
Even subtle vocal nuances and cinematic effects are rendered with realism and precision, ensuring every line of dialogue cuts through without distortion.
