Samsung HW-B750D vs Yamaha SR-B40A

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Samsung HW-B750D comes out ahead by a narrow margin (4.6 vs 4.4). The gap is mostly about TV-room upgrades where a true 5.1 setup and a wireless subwoofer matter more than authentic Dolby Atmos — read the strengths below before deciding.

$280

The HW-B750D is RTINGS' top pick for under-$300 in 2026, and it earns it by being the only legit 5.1 system at this price tier. The wireless subwoofer and side-firing channels create a wider soundstage than 2.1 competitors can virtualize, and the Bass Boost and Adaptive Sound modes adapt the EQ to whatever you're playing. Trade-off: no native Dolby Atmos — but at $280 with a subwoofer included, that's a fair trade.

Strengths
  • 5.1 channel system with wireless subwoofer included — only true 5.1 setup in this round-up
  • Side-firing speakers widen the soundstage beyond what 2.1 competitors deliver
  • DTS Virtual:X processing creates pseudo-height channels without upfiring drivers
Watch-outs
  • No true Dolby Atmos decoding — relies on DTS Virtual:X virtualization
  • Wireless subwoofer occasionally drops connection in larger rooms
  • Build feels less premium than the Polk Audio Signa S4
Yamaha SR-B40A
Ranked #4 in Best Soundbars Under $300
Yamaha SR-B40A
$300

The SR-B40A is the smaller-room specialist. Yamaha's tuning prioritizes dialog clarity and balanced tonal response over raw volume, which makes it the right pick for apartments and bedrooms where the Samsung HW-B750D or Polk Audio Signa S4 would overwhelm the space. Virtual Atmos is decent but predictably not on par with the real upfiring channels on the Signa S4. The Clear Voice mode is the standout feature.

Strengths
  • Optimized for small-to-medium rooms — apartment-friendly sound balance
  • Virtual Dolby Atmos via Yamaha's DSP processing
  • Clear Voice mode is one of the most natural dialog enhancers in this round-up
Watch-outs
  • 2.1 channel layout — loses to the Samsung HW-B750D and Vizio M-Series 5.1 on surround capability
  • Virtualized Atmos — no real upfiring drivers like the Polk Audio Signa S4
  • Sometimes sits at or just above $300 — buy on sale to fit budget

How they stack up

Samsung HW-B750D

Only true 5.1 system in this lineup. Beats the Polk Audio Signa S4, Yamaha SR-B40A, Polk Audio Signa S2, and Vizio M-Series 5.1 on side-channel width but loses to the Signa S4 on real Dolby Atmos support. Closest competitor on price-per-channel-count is the Vizio M-Series 5.1.

Yamaha SR-B40A

Best dialog clarity in this lineup along with the Polk Audio Signa S4. Smaller-room focus differentiates it from the Samsung HW-B750D and Vizio M-Series 5.1's bigger-room 5.1 setups. Same channel count as the Polk Audio Signa S2 but with virtual Atmos that the Signa S2 lacks.
