No. Mounted bookshelf with correct angle is your best bet.

$99 for me. Still a deal.
If you can't run speaker wire (rental, wife complaining about aesthetics, toddler tugging on any visible cords, etc.), these actually make nice front mounted rears. Don't confuse it for sounding anything like a real 5.1 layout, but if you have two rear channels on your receiver going to waste, it's better than nothing. The rear sounds do get projected differently - ceiling bounce. Whether it is worth the novelty depends entirely on if you have $99 to blow.
Most content is 2.1 anyway, so you're probably better off getting two great mains and a sub.

I'm not sure calling it a "full-range speaker" is really correct also.Technically BB has it listed as a "Tower Speaker Height Module Pair".Because it's designed to reflect the sound off the ceiling prior to listening, is one reason for the different specs/measurements.
so because the speaker is angled makes it not a full range speaker? A full-range loudspeaker drive unit is defined as a driver which reproduces as much of the audible frequency range as possible, within the limitations imposed by the physical constraints of a specific design.

lol no it's not the angle, actually you pointed the main reason, design constraints.
Knowing what a woofer/driver and a speaker is/does will help.
Calling this a full range speaker is just as confusing.
My JBL Extreme I use in the garage or a soundbar is technically a full range speaker.
Most people wouldn't call them that imo.

As you pointed out this "speaker" is designed for a specific purpose and it it's frequency range reflects that.

it's physical constraints ie the size, material of the cone define the frequency range . This is a cheap full range speaker placed in a box at an angle for reflective purposes. The frequency response is not that critical because they are atmos channels. The JBL extreme you have if it only has 1 active speaker - that speaker is a full range speaker. They use passive radiators to reinforce bass. The Extreme 3 though has tweeters also, do in that configuration that is a woofer and tweeter with a passive radiator. I mean seriously your argument has no logic.

lol woofer,driver, speaker,channel! 🤔

Frequency range defined by physical constraints but then its response isn't critical! 🤔

You might want to do a little more research so then you can make a logical argument !

Ok you're truly starting to annoy me. The reason they chose a cheap full range speaker in this device was because Atmos channels are not that demanding so frequency response is not that critical in this type of speaker. You're so wrong, but maybe some more emojis will help you since your knowledge base is truly lacking.

lol don't blame me, I'm just pointing out the incorrect information you' keep providing!

Another example:
If these Atmos "channels" are not that demanding & frequency response is not critical.
What would be the advantage/benefit to an "expensive" speaker or device or woofer or driver, not sure which to call it since you keep intermixing them?
