Nakamichi Shockwafe 11.2.6 review

What the maker puts in writing

• “PRIME SPECIAL, WHILE SUPPLIES LAST @ $1677 (save $822). Built on 70+ years of audio legacy”
• “Dual 10” wireless subs add greater low-frequency authority, while bipolar height speakers fire from both sides and above to create the presence of 6 d[iscrete height channels]”
• “IMPORTANT SIZE NOTICE: Soundbar: 4.5” H x 54.0” W x 9.0” D / 32.5 lbs, Subwoofer (Each): 22.5” H x 12.6” W x 12.8” D / 32.7 lbs”
• “The soundbar’s wide 54” chassis is built to move serious air because real theater-scale sound requires physical size”
• “DUAL 10” SUBWOOFERS deliver deeper bass with greater speed and definition. The flared port design moves air efficiently”
• “HDMI eARC and two HDMI 2.1 inputs support 4K 120Hz Dolby Vision and HDR10+. AirPlay or Bluetooth”

Read the size notice before the specification

Bar: 4.5 × 54.0 × 9.0 in — 32.5 lb. Each subwoofer: 22.5 × 12.6 × 12.8 in — 32.7 lb.

Two of those numbers decide whether you can own this system, and they are not the width.

Nine inches deep. A typical television unit is 14 to 16 inches deep, so the bar takes most of the shelf — and may foul the television’s own feet, which on many sets sit toward the front.

Thirty-two and a half pounds. That rules out a good many wall brackets.

And two subwoofers at 32.7 lb each means 65 lb of cabinet has to go somewhere in the room, in two places, because two subwoofers only pay off when they are not next to each other.

At least nine listings on this shelf publish no dimensions at all. On a product whose first job is to fit under a television, Nakamichi’s capitalized notice is the most useful paragraph here.

Bipolar height, which is a real design answer

A conventional up-firing driver points at the ceiling, and you hear the reflection — so the effect depends on your ceiling being flat, reflective, and at a reasonable height. A sloped or acoustically absorbent ceiling kills it.

Bipolar speakers fire “from both sides and above”. Part of the energy goes to the side walls instead, so the effect degrades gracefully rather than vanishing.

That is the same reasoning behind JBL’s MultiBeam, which bounces sound off side walls — except JBL has no height drivers at all, and this has six.

Two ten-inch subwoofers, and why two

Not for output — for placement. Bass wavelengths are meters long, so they interact with the room to create standing waves: spots where bass piles up and spots where it disappears. Two subwoofers in different positions fill each other’s nulls, so the bass is similar across the sofa rather than correct at one cushion.

The flared port is the right detail to publish: a sharp-edged port generates audible turbulence at high excursion, and flaring the mouth reduces it.

Two HDMI 2.1 inputs

All four Nakamichi listings publish an input count, and nobody else on this shelf does.

Most bars here offer eARC only, which means every source plugs into the television and the TV sends audio back down one cable. That works and makes the TV the switcher.

HDMI 2.1 inputs at 4K 120Hz matter specifically for a games console: route it through the bar and you keep the high refresh rate while the bar gets the full uncompressed audio.

The saving, honestly

PRIME SPECIAL, WHILE SUPPLIES LAST @ $1677 (save $822).

All four Nakamichi pages open this way — $822, $1,011, $1,211 and $1,620 — which is $4,664 of stated savings against reference prices each page sets for itself, with no date and no retailer.

A discount is verifiable only against a price actually charged somewhere, for some period. Read these as positioning.

What the numbers do show clearly is the ladder: $988, $1,677, $2,288, $2,588, $3,579 — and the steps buy subwoofer size and count, not channels.

What is not published

No room calibration, on a system with six ceiling-dependent height channels and two room-dependent subwoofers. Five cheaper bars on this shelf have it, from $99.99.

No frequency response — Nakamichi’s 12-inch Dragons publish 19 Hz. No total power figure. No system weight.
