TX-SR353 5.1 Channel A/V Receiver with HDCP2.2/HDR and Bluetooth

Soundbars definitely have their place, but if explosive surround-sound is what you’re dreaming of — without an eye-watering price tag — check out the TX-SR353 5.1 Channel A/V Receiver. It serves as a next-gen 4K/60 Hz-ready hub for all your devices (game consoles, STBs, VCRs, and BD players) and sends everything to your TV through a single HDMI. But best of all, its discrete analog amps immerse you in 140W/ch of clear and dynamic sound, whether it’s from your regular TV shows, DTS-HD Master Audio-encoded Blu-rays, an AM/FM radio station, or MP3s played via USB. So if you want to fix your thin flatscreen sound, do it properly and do it affordably with this compact A/V solution.

  • 140W per channel
  • True driving power from discrete amp circuits
  • HDMI 4 In / 1 Out
  • HDMI & HDCP 2.2 / HDR for 4K UltraHD
  • Built-in Bluetooth audio streaming

Enjoy Perfect High-Definition Movie Soundtracks

The TX-SR353 decodes Dolby TrueHD and DTS-HD Master Audio, two lossless Blu-ray formats that deliver a soundtrack identical to the studio master, so you're hearing it exactly as it's meant to be heard.

HDMI 4 In / 1 Out: Ready for 4K UltraHD

All HDMI terminals support the latest TV displays with four inputs handling HDCP 2.2 copy protection, HDR (High Dynamic Range) with BT.2020 support, and 4:4:4 color space encoded in content from movie studios, broadcasters, and streaming services for next-generation UltraHD.

True Power from Discrete Amplifiers

Discrete amps deliver high instantaneous current to increase speaker control for accurate and dynamic audio reproduction. This precise power is the cornerstone of Onkyo's amplification philosophy. This gives the TX-SR353 140 W/ch (6 ohms, 1kHz, 1.0% THD, 1 channel driven) 80 W/ch (8 ohms, 20Hz – 20kHz, 0.08% THD, 2 channels driven, FTC).

HDMI Video Up-Conversion and ARC

HDMI enables every video input signal to be up-converted and sent to your TV through one HDMI cable, and for your TV's sound to be processed through your TX-SR353 for cinematic surround sound.

Built-In Bluetooth

Stream virtually any audio from your smartphone, tablet, or PC to your home theater for clear and powerful sound.

Easy Connection Diagrams

Connections to speakers and external source devices are illustrated and clearly labeled on the back panel.

Room Calibration Made Easy

AccuEQ measures and corrects speaker distances, output levels, crossover frequencies, and frequency response from one quick and easy listening position to ensure clear and balanced surround sound.



TSi300 3-Way Tower Speaker with Two 5-1/4" Drivers (Black)

  • Unlike other speakers in this price range, TSi enclosures are constructed of extensively braced, solid MDF with 3/4-inch baffles. This virtually eliminates internal resonances and damps energy-stealing vibrations.
  • Beautiful pewter accents, a high gloss piano-finish black top plate and your choice of stylish black or cherry wood-grain finishes make TSi speakers a part of your decor.
  • Polk's proprietary, patented Dynamic Balance technology allows the engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
  • 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.
  • TSi design combines smaller drivers (for more overall driver area with less driver mass) and narrow baffle geometry (taking up less than one square foot of floor space), for wider range and more spacious sound-staging.
  • Unlike horns or metal domes, silk dome tweeters deliver clear and detailed highs, without fatigue, even at high volume.
  • Durable, efficient, and tuned with the Dynamic Balance process, TSi Series polycarbonate cones produce smooth, natural sound.
