DefiniTech never disappoints. White van speakers at boutique prices.
These speakers seem just odd.
The passive radiator is too small. Simple physics says that it needs to have an area significantly larger than the bass driver - its whole point is to take over shifting air at frequencies below where the bass driver has given up. I have a horrid feeling that the passive radiator doesn't even have a spider - the really cheap small ones don't. Which may be why the additional mass is apparent held on with a screw. A too small passive radiator is going to run into excursion problems very quickly, and is probably the source of a large fraction of the low frequency distortion. (I wonder, if the passive radiator is indeed spiderless, whether it is hitting a rocking mode near 500Hz, and that is where that distortion hump comes from. Just a thought.)
If this speaker is intended to be used with a sub-bass system, why does it have a passive radiator at all? (This is a question I have I of any small vented speaker intended for such use.) A fourth order alignment is intended to allow bass extension below where the excursion limit of the driver would prevent the speaker going. It has pros and cons. If a speaker is to be used with a sub, design it sealed. It will be cheaper, and you will be less likely run into unfortunate compromises. And this speaker sure has them. Despite the passive bass radiator it doesn't even seem to have enough bass extension to get into a region where it would match with a conventional sub.
One can only conclude that this is another example of a speaker designed by the marketing department.
That seems like the charitable interpretation, designed as wall mount rears crossed over to a sub, but as @Francis Vaughan points out, just using a simple sealed box would be a better and cheaper solution.
-3dB down at 100Hz with a 5.25" Woofer. Why?
You'd need something like 150Hz crossover frequency with this, why would they do that?
Then you just live with the reduced bass response?They are not catering for the sub crowd.
Thats the exact opposite of what they do, they insist on using these with a sub.They are not catering for the sub crowd.

Doesn't matter the content, with a flat response down to only 150Hz you'd be missing half of it. Thats ridiculous when we're not talking about a 50$ bluetooth speaker.
That would have made the bass response much shallower and thus required too high of a crossover.If they did, wouldn't they have gone for a sealed cabinet?

Why are so many manufacturers designing and producing these toy-sized speakers if there isn't a market for them?

They may work as desktops or surrounds (in a small room) but that's not how the largest majority of people will use them.
Imagine the results if Amir had simply used the Noise Harvester
I went through a DefTec phase not too long ago (preASR); their towers received glowing reviews. Their amps must have been glowing as well because I had them fail in their "powered towers" as well as their subs. Our local audio dealer (Paradyme) stopped carrying DefTec and replaced with GoldenEar. Likely a step up, hopefully Amir will get some Tritons to test however I am forever soured on the idea of putting a sub in with a floorstanding speaker.
Didn’t know about the Audioquest thing, maybe just for the $ but not a good look for Gross (IMO). Yet another TGFASRHmmmm.....Def Tech, GoldenEar, and let's not forget Polk Audio....all are the "brain-children" (or "devil's spawn" if you like) of one Sanford ("Sandy") Gross....the P.T. Barnum of the U.S. consumer speaker market, and.....wait for it....he's sold GoldenEar to Audioquest! How appropriate!
Sandy will be enjoying a well deserved but brief retirement until he gets the itch once again to spawn a new line of speakers that'll very likely keep the passive radiator narrative...Sandy knows the Zeitgeist of the North Am. Mid-Fi speaker market.....for him it's all about the smile curve, sparkly trebles, and a fulsome yet flatulent bottom octave character.....

While I want my stereo to be the focus in my living space, the manufactures of products like this speaker are right IMHO, the masses do not want anything to do with large speakers. Vast quantities of people do want some decent sound from time to time but they will happily compromise a bit on the sound for something small or better yet invisible. None of these folks will notice or care if the sub and mid do not blend smoothly in the 100-150hrz region. *I blame Bose, they got the idea in the mind of the masses that small speakers sound good and read enough replies on fora that they don't want large speakers in a room. Hence the requests for bluetooth things and soundbars and wireless as if pulling a speaker wire which last a century is a lot of work.
On the other hand my GF still listens to music on the macbook pro speakers...
As an aside, I bought the Revel M8 in that package a while back. Will test it at some point.The REVEL version is $1500 with no-subwoofer included.
