- “Dolby Atmos and DTS:X bring multidimensional sound to your room—including up-firing height channels”
- “Meridian Horizon upmixes two-channel sound for more immersive listening. Newly designed speaker driver, chamber, and subwoofer improves sound pressure”

Five height channels, and some of them are behind you
A channel count reads front . sub . height. 9.1.5 is nine horizontal channels, one subwoofer and five up-firing drivers.
The sentence that matters is in the first bullet: six-channel wireless rear speakers with up-firing height channels.
So the rears are not plain surrounds. They carry their own ceiling-bounced drivers — which means the height layer exists behind you as well as in front.
That is what an Atmos mix is actually written for: objects placed overhead-front and overhead-rear, moving between them.
The rest of this shelf: Samsung’s two 3.1.2 bars have two height drivers, both at the front, and its European HW-Q930H four. LG’s own S70TY has one, and Nakamichi’s Shockwafe 9.2.4 four. Eight bars have none. Only four Nakamichi systems have more, at six, for $1,677 to $3,579 on October 25, 2026.
Which is why the calibration belongs here
Up-firing drivers do not fire at you. They fire at the ceiling, and you hear what comes back.
So the whole effect rests on a variable the manufacturer cannot control: ceiling height, flatness, absorbency. Sloped plaster scatters it; acoustic tile swallows it.
With five height drivers, that is five effects standing or falling on your room.
AI Room Calibration Pro optimizes sound in your room with spatial awareness technology.
Several bars here calibrate the room; this is the only one doing it for five height channels. The $988 Nakamichi Shockwafe 9.2.4 publishes none.
Against the Nakamichi at $988
LG S95QR — $699.99 — 9.1.5 — five height channels, rears with their own up-firing drivers, AI Room Calibration Pro, Meridian Horizon upmixing, 14,969 g.
Nakamichi Shockwafe 9.2.4 — $988 — two 10-inch subwoofers, four height channels, four discrete surround speakers, 3 HDMI inputs, and a published size notice (bar 45.5 in, subs 20.2 in tall at 23.8 lb each). 36,287 g.
LG gives one more height channel and calibration. Nakamichi gives two ten-inch subwoofers and HDMI switching.
Bass first: Nakamichi. Height layer first: LG.
Meridian, and a center channel
Meridian Horizon upmixes stereo across all nine channels — which matters more than it sounds, because most of what people watch is not Atmos. Broadcast television, older films and most streaming music are two-channel.
And there is a center channel, so dialogue has its own driver. Most bars under $300 on this shelf are 2.0 or 2.1, where the voice floats between two speakers.
What is not published
No dimensions at all, on a system of four separate boxes. That is the gap, and Nakamichi is the only maker here that fills it — with a capitalized “IMPORTANT SIZE NOTICE” on each of its listings, because one of its bars is 58 inches wide and one of its subwoofers weighs 80 lb.
No power figure, where JBL publishes 750 W and Nakamichi 3000. No subwoofer driver size, where JBL publishes 10 inches and Sony 160 mm.
14,969 g is published, which makes this the heaviest system here outside Nakamichi.

What gets asked most
What do five height channels get you?
A height layer that goes behind you, which almost nothing else on this shelf offers at this price. The channel count reads front.sub.height: 9.1.5 is nine horizontal channels, a subwoofer and five up-firing drivers. Crucially, LG publishes "six-channel wireless rear speakers with up-firing height channels" — so the rears are not plain surrounds, they carry their own ceiling-bounced drivers. That is what an Atmos mix actually asks for: objects placed overhead in front and overhead behind. For comparison, Samsung’s 3.1.2 bars have two height drivers, both at the front. LG’s own S70TY has one. The only bars here with more are the four Nakamichi systems, at six, costing $988 to $3,579.
Does room calibration matter more on this bar?
Yes, and it is the right pairing. Up-firing height drivers do not fire at you — they fire at the ceiling, and you hear the reflection. So the entire effect depends on a variable the maker cannot control: your ceiling’s height, flatness and absorbency. A sloped ceiling scatters the reflection; an acoustic tile ceiling absorbs it. On a system with five height drivers, that is five effects standing or falling on the room. LG publishes "AI Room Calibration Pro optimizes sound in your room with spatial awareness technology" — measurement and correction of exactly that. Five of fourteen bars here calibrate, and this is the only one doing it for five height channels. The $988 Nakamichi Shockwafe 9.2.4 publishes no calibration at all.
Is it better value than the Nakamichi Shockwafe at $988?
On published specification the LG looks stronger per dollar, and the Nakamichi answers with physical scale. LG S95QR, $699.99, 9.1.5 — nine horizontal, five height, subwoofer, rears with their own up-firing drivers, AI Room Calibration Pro, Meridian upmixing, and 33 lb (15 kg). Nakamichi Shockwafe 9.2.4, $988 — nine horizontal, two subwoofers at 10 inches each, four height, four discrete surround speakers, 3 HDMI inputs, and a published size notice: bar 45.5 in, subs 20.2 in tall at 23.8 lb each, 80 lb (36.3 kg) total. So LG gives you one more height channel and calibration; Nakamichi gives you two ten-inch subwoofers and HDMI switching. If bass is the priority, Nakamichi. If the height layer is, LG.
