Channel configuration is the one thing most of these listings name, so that is what the line orders them by. It describes parts rather than performance, and the distance between marks means nothing more than the next one along.
Further right is a configuration with more parts named. The marks are evenly spaced because these are names, not a measured scale.
Amazon Fire TV Soundbar. The same mark, and the shortest list of stated features on this page. What the listing does not mention is not evidence of anything either way.
Samsung HW-B400F 2.0ch Soundbar. At the left mark with one other bar. The listing names a built-in subwoofer, so the whole system is the one cabinet under the screen.
TCL S55H 2.1 Soundbar with Wireless Subwoofer. The middle mark, and the only entry whose low end lives in a second box. That box needs floor space and a socket, neither of which the line can show you.
Amazon Fire TV Soundbar Plus. The right-hand mark, and the only listing here naming a center channel as part of the configuration. That is the part of a bar that carries speech.
This listing describes the bar without naming a channel configuration. There is no figure to place, so nothing is placed, and the card carries what the listing does say.
Bose TV Speaker
Channel count not stated
Replace the sound coming out of the panel with a box that fits under it, and state plainly what that box is made of.
Everything is in the cabinet under the screen. One box, one plug, one position to measure.
The low end lives in a second box that needs floor space, a socket, and somewhere it will not be walked into.
Note
None of these listings states the width of the cabinet. That figure has to come from the manufacturer documentation for the exact model, and it has to be checked against the space under your screen before the purchase.
Note
Nothing on this page is described as compatible with a particular television model. What each listing states about its own connections is the whole of what is repeated here.

The listing names HDMI-ARC and Bluetooth. It does not name a channel configuration, which is why it sits beside the line rather than on it.
