Problems, parts and running costs

Summary

A 2.1-channel soundbar with a wireless subwoofer for a small or medium room where an optical or Bluetooth TV connection is enough. Check two things before buying: it has no HDMI, so there is no ARC, eARC or video passthrough, and Samsung also used the HW-C450 name on a completely different 2010 model.

Strengths

  • Simple 2.1 setup: the subwoofer auto-pairs over a 5.8GHz link once both power cords are plugged in.
  • An optical cable or Bluetooth is enough for a TV that does not need HDMI ARC.
  • Voice Enhance and Night Mode can lift dialogue or tame loud peaks.
  • The bar can become a 4.1-channel system with Samsung’s SWA-9200S rear kit.
  • Firmware is user-appliable by USB from Samsung’s support page.
  • A low-profile bar sits neatly under a TV.

Weaknesses

  • No HDMI at all, so no ARC, eARC, CEC or video passthrough; TV volume control falls back to Bluetooth or an IR remote mode.
  • No dedicated centre speaker, so dialogue is reproduced by the left and right channels.
  • No Wi-Fi, AirPlay, Chromecast or built-in voice assistant.
  • Bluetooth pairs one device at a time and reaches only about 10 m.
  • The wireless subwoofer still needs its own power outlet and a 5.8GHz link that walls and interference can disrupt.
  • No lab has published frequency-response, maximum SPL or distortion figures for this exact model.

Connectivity and TV control

The manual lists exactly three connections: one optical digital audio input, a USB port rated 5V/0.5A and Bluetooth. There is no HDMI of any kind, so the bar cannot act as an HDMI switch, cannot pass 4K video and cannot use HDMI-CEC. A TV with an optical output needs no other audio cable, and volume control then depends on Samsung’s Bluetooth integration or on the remote’s OFF-TV, SAMSUNG-TV and ALL-TV IR modes. Some TVs and streaming remotes will not drive it, and buyers who want one-remote control through HDMI should look at an ARC-equipped bar instead. Bluetooth is a single connection with about 10 m of range, so pairing a second device means dropping the first.

Sound and setup

Samsung rates the bar at 40W × 2 channels and the subwoofer at 220W, and positions the system as an upgrade over built-in TV speakers. Playback covers LPCM stereo, Dolby Digital and DTS 2.0; DTS Virtual:X is a sound mode that widens the image rather than a format the bar decodes. Modes include Standard, Surround Sound, Game, Adaptive, DTS Virtual:X and Bass Boost, with Voice Enhance and Night Mode for dialogue and late-night peaks. There is no centre channel, so that processing cannot create a real centre speaker. The sub connects wirelessly but still needs mains power, and it drops to standby when the bar powers off. Setup is simple: connect both power cords and the link indicator turns solid blue when the sub is paired. If the sub goes quiet, Samsung’s recovery is to hold ID SET on the back of the subwoofer, then Up on the remote, until the light is solid blue again.

Running costs and upkeep

The system has no filters, cartridges or subscriptions, so required recurring costs sit at $0 a year. Standby is 2.0W, and Samsung’s regional ratings are 25W for the bar and 40W for the subwoofer; an illustrative four hours a day at those ratings plus idle time lands near $20 a year at $0.20/kWh, but that is a rating, not a measured draw. Spare parts are the real expense if something is lost: a genuine replacement remote runs about $99.99 to $104.95 (iFixit and Samsung Parts USA, 2026), a power cord about $14.99 (Impact Computers, 2026) and an optical cable about $19.98 (Impact Computers, 2026). Firmware can be updated by USB, and Samsung’s support page lists version 1020/1019 from September 2025. One owner reported static and a loose subwoofer connector after more than two years, and a four-year retailer service plan that did not get it repaired — a single account, not a failure rate.

Is it worth it?

Stock of the exact 2023 model is thin. Walmart Business listed it at $197.99 and Connection at $231.24 (both October 2026, both out of stock or unavailable), while Best Buy showed a $45.99 clearance figure against a $199.99 comparison on a page marked no longer available. At those real prices the value is weak: Samsung’s newer HW-B550F, with HDMI ARC, was $179.99 (Samsung US, 2026), a 3.1-channel HW-B650F was $249.99 (Best Buy, 2026), and a Vizio V21x-J8 with HDMI ARC was about $150 (Walmart Business, 2026). Below about $110 the C450 is a sensible optical/Bluetooth bar for a secondary room; above roughly $150, an ARC-equipped model is the better buy.

Which model this is

This page covers the 2023 US C-Series HW-C450/ZA, a 2.1-channel bar with the PS-WC45T wireless subwoofer; the EU/UK code is HW-C450/XEU and the manual is shared with the C460 and C460G. The Amazon listing for the Titan Black model is ASIN B0BVWFZC7L. Samsung also sold a completely different HW-C450 in 2010, roughly 37.7 inches wide with analog input and an older subwoofer, so confirm the year and part number before buying. Do not merge it with the Q-, S- or B-series bars, or with the older PS-WK450 subwoofer.
