Main trade-off
JBL Bar 1300X MK2
Rear batteries need charging and cannot promise all-day playback.
Head-to-head
Choose JBL 1300X MK2 if there are no power outlets beside the sofa and you can recharge the detachable rears. Choose Q990F for a permanent surround setup with a smaller subwoofer cabinet and two confirmed 4K 120 Hz inputs. JBL adds a third HDMI input, but that alone is not a bandwidth guarantee.
Before you choose
JBL’s 225-square-inch cabinet base is about 2.34 times Samsung’s 96.04-square-inch base.
What this is based on
The ratio is (15 × 15) ÷ (9.8 × 9.8). This is a floor-space comparison, not a bass-output comparison.
Main trade-off
Rear batteries need charging and cannot promise all-day playback.
Main trade-off
Both rear speakers still need electrical power.
Compare JBL 1300X MK2 and Samsung Q990F by rear power, subwoofer footprint and HDMI routing. The best fit depends on the room behind your sofa.
Choose between rechargeable rear speakers and permanently powered rears before comparing channel counts.
Winner by situation
JBL can play from charged rear batteries.
No equivalent JBL bandwidth claim is made here.
Check individual width and depth, not only total area.
Samsung’s rear speakers remain powered.
What matters in practice
JBL’s 225-square-inch cabinet base is about 2.34 times Samsung’s 96.04-square-inch base.
The ratio is (15 × 15) ÷ (9.8 × 9.8). This is a floor-space comparison, not a bass-output comparison.
A 50-inch usable stand fits the 40.6-inch JBL bar and the 48.5-inch Samsung bar, but not JBL’s 55.3-inch docked configuration.
Decide where charging will happen before treating the detached width as the only size that matters.
JBL has the higher source count. Samsung has two manufacturer-confirmed 4K 120 Hz inputs in the researched specifications.
A third connector is useful for another player or streaming box, but it does not by itself establish support for a particular console video mode.
Try your real numbers
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
It needs 55.3 inches of width with its detachable speakers docked, more than your 48 inches.
It needs 48.5 inches of width, more than your 48 inches.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.
JBL, Bar 1300XMK2
Choose the 1300X MK2 when rear-speaker outlets are the obstacle to a complete surround setup. Three direct HDMI inputs simplify a busy TV, but the detachable speakers bring a charging routine and the subwoofer is substantial.
Samsung, HW-Q990F/ZA
The Q990F puts the subwoofer and two rear speakers in the same box and accepts two 4K 120 Hz sources directly. Choose it when you have rear-speaker locations ready, not just space beneath the TV.
Meaningful differences
| What changes | JBL Bar 1300X MK2 | Samsung HW-Q990F | Why it matters |
|---|---|---|---|
| Rear-speaker power | Rechargeable detachable units | Powered rear speakers | JBL trades power cords at the sofa for a charging routine. |
| Source inputs | 3 | 2 | JBL accepts one more directly connected source. |
| Confirmed 4K 120 Hz passthrough | Not established in this comparison | Supported on both inputs | Use Samsung when verified high-refresh passthrough is a hard requirement. |
| Subwoofer width × depth | 15 × 15 inches | 9.8 × 9.8 inches | The JBL subwoofer needs much more cabinet footprint. |
| Bar width | 40.6 inches detached, 55.3 docked | 48.5 inches | JBL is narrower in playback configuration but wider when docked. |
