Product Details

Polk Audio White Rectangular Three-Way In-Wall Surround Loudspeaker, Model LCIRTSFX

You no longer have to choose between having ultimate performance home theater and uncluttered room decor. You can have both with Polk Audio RTS Series THX Ultra2 certified built-in speakers. The RTS FX is a purpose-designed suround channel loudspeaker for use in a complete built-in home theater system. Mix and match the RTS FX with Polk's RTS105, RTS100 and RTS C THX Ultra2 certified built-in speakers and Polk's CSW built-in subwoofers and you'll have a home theater audio system that exceeds the performance of most free-standing speaker systems while remaining virtually undetectable. Like the other models in the RTS Built-in Series, the RTS FX is engineered for predictably superior home theater performance. The RTS FX features technologies used in Polk's critically acclaimed LSi Series of freestanding speakers to deliver the sound quality of stand-alone models. Just as important, installation is easy, and who doesn’t love the sound of that?


  • Dual-diffuse midrange and tweeter arrays
    Dual midrange drivers and tweeters are set at precise angles to disperse sound over an extremely wide area to create a diffuse sound pattern
  • Solid/Diffuse Switch
    Affords greater placement flexibility for the surround effect you desire. In “Solid” mode, all drivers and tweeters are in-phase, producing solid, discrete sound-staging (The THX default setting). In the “Diffuse” setting, the rear facing tweeter array is out of phase with the front facing array for more diffuse and un-localizable surround imaging
  • Integrated Performance Enclosure®
    The LCi-RTS FX features an integrated "perfect volume" performance enclosure to ensure superb performance and superior room-to-room sound isolation every time
  • Ideal for retrofit and new construction
    Because the performance enclosure is the same size as the cutout, the LCi-RTS FX installs easily in a post construction project
  • Stud-Lock Mounting System™
    (patent-pending and sold separately) This system creates a rigid platform for the LCi-RTS FX, increasing bass performance, clarity and reducing unwanted structure borne vibration
  • THX® Ultra2-certified
    Polk RTS products meet or exceed THX's toughest performance standards. You’re assured of great surround sound performance and exceptional dynamic range
  • Audiophile Grade Drivers and Tweeters
    We’ve incorporated the same driver technologies as found in our highly acclaimed LSi and LCi series of freestanding and built-in speakers
  • Aerated polypropylene Dynamic Balance™ driver Cones
    Stiff yet lightweight for superb midrange clarity, punchy bass and high efficiency. These cones are 20% lighter than conventional polypropylene and 35% lighter than aluminum cones
  • Enclosure Stiffening
    Each driver is screwed into the back of the performance enclosure to stiffen the enclosure. Enclosure resonance is reduced for less distortion and less wasted energy. RTS speakers play louder and cleaner than competing self-enclosed in-wall speakers
  • Composite Driver Basket
    Molded composite driver baskets are non-resonant and incredibly rigid for distortion-free sound
  • Ring Radiator tweeter
    The ring radiator design, found in $35,000 free-standing speakers, delivers smooth, extended highs with excellent accuracy and astonishing detail. A 15º swivel design ensures excellent imaging off-axis, while a redesigned faceplate geometry further refines off-axis characteristics
  • High-quality crossover networks
    Assure seamlessness to reproduce always inspiring performances
  • Acoustically Transparent Grilles
    Perforated metal grilles can cause diffraction. Our specially designed 3-piece grille assemblies, using aluminum mesh, provide a 75% open area for superior on- and off-axis response. The LCi-RTS FX ships with two grilles: One cloth grille for maximum sonic performance, one aluminum mesh for a more traditional appearance
  • Wall Distance Switch
    Lowers output only in the low-midrange/ upper bass to eliminate “boominess.”
  • Tweeter Attenuation Switch
    Engages a pass-band filter to compensate for overly reflective rooms, decreasing unwanted glare and harshness without decreasing the high-end frequencies
