Keep using its built-in speakers if they sound clear and full enough for your room; consider external audio if dialogue is hard to follow, the sound feels thin, or you want a more immersive experience. The screen’s diagonal size can help you judge physical fit, but it does not determine whether you need better sound. Dolby describes the choice as a matter of preference and whether you want better sound than the TV provides.
When a soundbar is worth considering
Start with what you want to improve, not the TV’s size. A soundbar is a straightforward way to add external TV audio, but how much it helps depends on the particular bar, the room, and the setup. Denon’s buying guide also notes that an AV receiver with separate speakers can make more sense for people seeking a more capable surround setup or who already own speakers.

- Dialogue is difficult to hear: Look for a soundbar with features aimed at clearer speech, and consider whether the issue is consistent across shows and sources.
- The sound feels thin: A soundbar may provide a fuller presentation; if stronger bass matters, check whether the bar includes or supports a subwoofer.
- You want a more immersive effect: Check whether the system is standalone or can work with a subwoofer or rear speakers. Add-on speaker compatibility varies by soundbar, according to Denon.
- You are satisfied now: There is no soundbar requirement tied to owning a 55-inch TV. Keep the built-in speakers unless you have a specific reason to upgrade.
How to choose between TV speakers, a soundbar, and separate speakers
| Option | Best reason to consider it | What to check |
|---|---|---|
| TV’s built-in speakers | The sound already works for your usual viewing | Dialogue clarity and volume from your usual seating distance |
| Soundbar | You want a relatively simple external audio upgrade | Dialogue features, placement, TV connection, width, and subwoofer or surround-speaker compatibility |
| AV receiver with separate speakers | You want a more capable surround system or already own speakers | Space, wiring, setup complexity, and component compatibility |
These are different approaches, not a universal ranking. Your room, budget, desired sound, and willingness to manage a more complex setup should guide the choice. Denon discusses these considerations in its buying guide.

Measure the space where the bar will sit or mount, and make sure it will not block the screen or other sensors. A 55-inch TV is measured diagonally, so its width is less than 55 inches; do not use the diagonal as the width of the opening available for a soundbar. Also check the TV’s stand, cabinet, and mounting arrangement before choosing a bar. Bose advises considering room size, TV size, width, and placement; its room-size guidance is manufacturer advice, not a universal acoustic rule.

Some products are designed around this TV size, but that does not make them right for every owner. For example, Sonance lists the SB46-55 as a fixed-width soundbar tailored to most 55-inch displays. Its current product specification gives a width of 48 inches and identifies a 55-inch diagonal display size. Those are manufacturer specifications, not independent test results. The SB46-55 is passive and requires amplification, so check the installation and amplification requirements rather than assuming it can connect like a powered soundbar.
Check the exact TV and connection before buying
Do not assume that a recommendation for one 55-inch television applies to every model. Check the soundbar’s supported connection methods against the exact TV model, and confirm any mounting or placement requirements. Samsung’s US soundbar guide provides recommendations across its lineup and advises checking compatibility; recommendations vary by TV and soundbar model.

Should you buy one?
Buy a soundbar only if you have identified a problem with the built-in sound or want a clear upgrade in dialogue, fullness, bass, or immersion. If the TV already sounds good to you, there is no need to add one simply because the screen is 55 inches. If your goal is higher-end surround sound—or you already have speakers—compare a receiver-based setup as well.
