Decoding Atmos and having height channels are two claims · review
A 9.2.4 system with two ten-inch subwoofers and four surround speakers, at 79.4 lb (36 kg) total.
In brief
Two ten-inch wireless subwoofers and four discrete surround speakers for under a thousand dollars — and a bar weighing six pounds, which tells you where the money went. It publishes no room calibration. Key figures: 9.2.4 channel Dolby Atmos and DTS:X surround soundbar system with dual 10 inch wireless subwoofers driven by amplifiers up to 600 W, four dedicated surround speakers, SSE MAX processing, HDMI eARC and three HDMI inputs with Dolby Vision and 4K HDR pass-through, with a bar of 3.6 × 45.5 × 3.0 in at 6.0 lb. Amazon.com had an offer at $988 on October 25, 2026.
Not output — placement.
Bass wavelengths are several meters long, so they interact with the dimensions of the room to produce standing waves: places where the bass piles up and places where it nearly disappears. Move the sofa three feet and the bass changes character entirely.
Two subwoofers in different positions excite different room modes, and the nulls of one get largely filled by the other. The result is bass that is roughly the same across the seating area instead of correct at one seat.
That is a technique normally found in custom installation, not in a soundbar box. At 10 inches each with amplifiers “up to 600W”, it is also the bass answer on this shelf below the $1,677 Shockwafe.
Four dedicated surround speakers create a wider, more immersive 360° sound field.
Which is the other thing this system does that most of the shelf cannot. JBL’s MultiBeam 3.0 steers sound off the side walls to imply surround; Sony’s S-Force Pro does it from the front speakers alone. Both are real techniques and both depend on your walls.
Four speakers placed around the room do not depend on anything.
Nakamichi publishes a size notice on each of its listings, and this one is revealing:
Bar: 3.6 × 45.5 × 3.0 in — 6.0 lb Each subwoofer: 20.2 × 12.0 × 13.6 in — 23.8 lb
Against its own Dragon: a bar of 4.4 × 58.1 × 7.7 in at 32.2 lb — five times the mass, more than twice the depth.
So the design is explicit: almost nothing in the front bar, everything in the subwoofers and the four separate speakers.
The advantage is that a 3-inch-deep, 45-inch bar fits under practically any television. The cost is a front stage with very little cabinet behind it.
Total system: 80 lb (36.3 kg), about 80 lb, consistent with 6 + 2 × 23.8 plus satellites.
HDMI eARC and 3 HDMI inputs with Dolby Vision and 4K HDR pass-through.
Most bars on this shelf offer eARC only — meaning every source plugs into the television, and the television sends audio back down one cable. That works, and it makes the TV the switcher.
Inputs on the bar let a console or a player route through it. All four Nakamichi listings publish an input count; nobody else on this shelf does.
No room calibration. On a system with four height channels bouncing off your ceiling and two subwoofers interacting with your room’s standing waves, that is the omission that matters — and five cheaper bars on this shelf have it, from $99.99 upward.
No frequency response, where Nakamichi’s own 12-inch Dragons publish 19 Hz. No total power figure — only the subwoofer amplifiers, at up to 600 W.

Because the problem in a real room is not output, it is where the bass is. Low frequencies have wavelengths of several meters, so they interact with the room’s dimensions to produce standing waves — places where the bass piles up and places where it almost vanishes. Move the sofa three feet and the bass changes completely. Two subwoofers in different positions excite different room modes, and the nulls of one are largely filled by the other, which smooths the response across the seating area rather than at a single point. Nakamichi calls it "an industry exclusive" and it is genuinely rare below the custom-install market. At 10 inches each with amplifiers "up to 600W", this is the bass answer on this shelf outside the Dragon models.
Because this system puts almost nothing in the bar, and the figures make the design plain. Nakamichi publishes a size notice on each of its listings here, and this one reads: bar 3.6 in H × 45.5 in W × 3.0 in D, 6.0 lb; each subwoofer 20.2 × 12.0 × 13.6 in, 23.8 lb. Compare its own Dragon: a bar of 4.4 × 58.1 × 7.7 in weighing 32.2 lb — five times the mass and more than twice the depth. So this is a slim front bar with four separate surround speakers and two subwoofers doing the work, where the Dragon is a full cabinet. The advantage is that a 3-inch-deep bar fits under almost any television. The cost is that the front stage has little cabinet volume behind it.
On a system with four height channels, yes. Up-firing height drivers fire at the ceiling and you hear the reflection, so the effect depends entirely on your ceiling’s height, flatness and absorbency — and two subwoofers placed in a room interact with its standing waves in ways no factory setting can anticipate. Room correction measures and compensates for both. At least five bars here have it, and the five named here all cost less than this: TCL’s AI Sonic at $99.99 and $138, Samsung’s SpaceFit at $379.99, Samsung’s QS700F via the TV microphone at $397.99, LG’s AI Room Calibration Pro at $699.99, and JBL, which "discovers how sound reflects off your walls and furniture", at $649.95. Nakamichi publishes none on any of its four systems.
