How To Choose Speaker For Soundbar

How to Choose Speakers for a Soundbar

Selecting speakers for a soundbar requires comprehensive consideration of sound quality, power, size, speaker type, and usage scenarios. Here's a detailed buying guide:

1. Speaker Type Selection

(1) Full-Range Speakers

Features: Cover mid-high frequencies, suitable for vocals and general music

Applications: Compact soundbars, mainly for TV audio or background music

Recommended size: 2-3 inches (50-75mm)

(2) Tweeter speakers

Features: Specialize in high frequencies (>5kHz), enhancing detail and clarity

Applications: Premium soundbars, used with mid-woofers

Recommended types: Silk dome (softer) or metal dome (brighter)

(3) Mid-Woofer speaker

Features: Handle low frequencies (<500Hz), boosting impact

Applications: Soundbars requiring bass effects, like for movies/games

Recommended size: 4-6.5 inches (100-165mm)

(4) Subwoofer speaker

Features: Specialize in ultra-low frequencies (<200Hz), delivering deep bass

Applications: Home theater-grade soundbars, typically external

Recommended size: 8-12 inches (200-300mm)

2. Key Parameters

(1) Power (Wattage)

Compact soundbars: 10-30W per speaker (total ≤50W)

Mid-high end: 30-100W per speaker (total 200W+)

Matching note: Speaker power must match soundbar amplifier

(2) Impedance

Common values: 4Ω, 6Ω, 8Ω

Matching rule: Speaker impedance ≥ amplifier rating

(3) Sensitivity

Definition: SPL at 1W/1m (dB)

Recommendation: ≥85dB (higher sensitivity = easier to drive)

(4) Frequency Response

Basic: 80Hz-20kHz (human hearing range)

Premium: 40Hz-25kHz (requires subwoofer)

3. Soundbar Speaker Configurations

(1) Basic (TV Audio)

Setup: 2× full-range (3", 20W) + 1× tweeter

Features: Clear vocals for news/variety shows

(2) Intermediate (Entertainment)

Setup: 2× mid-woofers (4", 50W) + 2× tweeters + external sub (8")

Features: Balanced sound for movies/games

(3) Flagship (Home Theater)

Setup: Multi-way system + wireless sub (12")

Features: Immersive surround sound (Dolby Atmos)

4. Purchasing Considerations

Room size:

Small (<20m²): Compact soundbar (≤100W total)

Large (>20m²): Multi-driver + high power (200W+)

Brand technologies:

Dolby/DTS decoding for audio formats

Wireless connectivity (Bluetooth/Wi-Fi)

Demo suggestions:

Test vocal clarity (news) and bass extension (explosion scenes)

5. Recommended Setups

Conclusion

Best value: 4" mid-woofer + tweeter combo

Premium experience: Multi-way + external sub
