Which soundbar should you buy without a separate subwoofer?
Our pick
Sonos Arc Ultra
Start with Sonos Arc Ultra if a 46.38-inch bar fits and you want Wi-Fi music plus optional Sonos expansion later. Choose Bose Smart Soundbar for a much smaller cabinet, or JBL Bar 300 MK2 if you need a separate HDMI source input. All three standard packages work without a separate bass box.
Why it fits this need
- No external subwoofer in the standard package
- Cabinet fits beneath the TV without blocking the screen
- Main trade-off
- There are no separate HDMI inputs for a console or disc player.
- Choose Bose Smart Soundbar instead when
- The TV stand is narrow or the screen sits low. Its cabinet is 27.34 inches wide and 2.21 inches high.
More reasons behind this pick
- The required TV connection and music source are supported
Choose a single soundbar by cabinet space, HDMI connections and upgrade options. Compare real one-bar packages without hidden bass-box requirements.

What matters in practice
How to choose for this need
Choose the one-bar layout you can place correctly. A missing external subwoofer is a space decision, not a promise of identical bass performance.
The bar still has to fit in three dimensions
Arc Ultra is 46.38 inches wide and 2.95 inches high. Bose Smart Soundbar is 27.34 inches wide and 2.21 inches high. JBL Bar 300 MK2 is 37 inches wide and 2 inches high. A wide stand does not guarantee enough vertical room below the screen, and upward-firing drivers should not be trapped beneath a shelf.
Keep the source connection in the decision
Arc Ultra and Bose Smart Soundbar have no separate HDMI source inputs. A console or disc player connects to the TV. JBL Bar 300 MK2 accepts one source directly, which can be useful on a crowded TV connection panel. Check the required video mode rather than assuming every HDMI input handles 4K at 120 Hz.
A later upgrade should have a real connection path
Sonos and Bose offer compatible branded subwoofers and surrounds. JBL Bar 300 MK2 can add two Cove M1 or two Cove P1 speakers with current firmware and JBL One setup. Klipsch Flexus Core 200 also provides an RCA output for a compatible conventional powered subwoofer. These are separate purchases. Compare the complete planned system and its floor space before choosing a bar for later expansion.
Worked example
Three single bars on a 40-inch TV stand
Assume 40 inches of usable stand width and 2.5 inches beneath the screen.
FormulaWidth margin = usable stand width − soundbar width. Height margin = screen gap − cabinet height.
- The stand has 40 inches of unobstructed width.
- The screen begins 2.5 inches above the stand.
- These checks exclude cable, ventilation and acoustic clearance.
| Scenario | Width margin | Height margin | Cabinet fit |
|---|---|---|---|
| Sonos Arc Ultra | −6.38 in | −0.45 in | Does not fit |
| Bose Smart Soundbar | 12.66 in | 0.29 in | Meets both measurements |
| JBL Bar 300 MK2 | 3.00 in | 0.50 in | Meets both measurements |
What that meansThe smaller Bose or low-profile JBL meets both cabinet constraints. Arc Ultra needs a different TV arrangement.
Keep in mindPositive margins do not replace the manufacturer’s placement and clearance instructions.
What this comparison cannot tell you
- Specifications establish fit and connections, not equal bass output or equal dialogue clarity.

JBL, Bar 300MK2
