Head-to-head
Sony BRAVIA Theater Bar 9 vs Bar 8: Bar 8 saves stand width, Bar 9 does not add another HDMI input
The short answer
Choose Bar 8 when the stand is under 51 inches wide or you would rather reserve money for a subwoofer. Choose Bar 9 when its wider cabinet fits and you want Sony’s larger 13-unit bar. Both keep 4K 120 Hz passthrough, so the larger model does not buy another HDMI input.
Before you choose
The reasoning and the trade-offs
A 48-inch stand separates these models cleanly
Bar 8 leaves roughly 4.69 inches of width margin, while Bar 9 exceeds the stand by about 3.18 inches.
What this is based on
Subtract the cabinet width from 48 inches. This is a simple physical fit check and does not include cable or side-driver clearance.

What matters in practice
The differences that matter
A 48-inch stand separates these models cleanly
Bar 8 leaves roughly 4.69 inches of width margin, while Bar 9 exceeds the stand by about 3.18 inches.
How we reached this conclusion
Subtract the cabinet width from 48 inches. This is a simple physical fit check and does not include cable or side-driver clearance.
Saving width does not sacrifice the high-refresh input
Both have one separate source input with manufacturer-confirmed 4K 120 Hz and VRR passthrough.
How we reached this conclusion
The larger model does not help when the actual problem is connecting two sources directly to the bar.
The accessory plan may outweigh the bar upgrade
Neither standard package includes a subwoofer or rear speakers.
How we reached this conclusion
Compare Bar 8 with the accessories you actually want against Bar 9 alone, rather than assuming the larger bar is already a complete surround package.
Try your real numbers
Will the soundbar fit under your TV?
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.
Sony BRAVIA Theater Bar 9
Does not meet these checksIt needs 51.18 inches of width, more than your 48 inches.
Sony BRAVIA Theater Bar 8
Meets these checks43.31 inches wide and 2.52 inches high, with 1 separate HDMI source input. It leaves 4.7 inches of total spare width.
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.
Choice A
Sony, HT-A9000

Checked facts

Sony, HT-A8000
