I have looked at them, but they are a little large for my situation, and still a little expensive here, but yes, cheaper than the WiiM Sub Pro. Also I don't think they can be very easily connected to what I have.
Splitting the AUX outlet on WiiM Mini to add Active Subwoofer?

Just note that the dip at 80Hz is due to the fact that RTINGS doesn't measure anechoically - i.e. this is the room contribution (I suspect front wall SBIR cancellation). You'll see a similar dip for all speakers they measure.
Also note that the Edifier sub doesn't have a high pass filter on the RCA outputs, meaning that crossing too high will result in an overlap region between the sub and Echo.
I wish I understood what all these technical things mean. I'm not sure what to do now.
I will see if the T5s is discounted in the upcoming sales and make a decision then.Thank you to everyone for their input and assistance thus far.
This is interesting. Maybe I should replace the Echo with the T5s instead rather than have both connected to the WiiM Mini? Would this be a better option perhaps? Your comment makes me wonder if the Echo might be unnecessary or even redundant in my suggested setup.

oh, really? didn't know that the RTINGs freq response curves are in-room. thanks for pointing that out
about the edifier sub not high-passing the RCA out: great point. didn't realise that was the case...
guess i should have read the earlier part of this thread in more detail before jumping in to comment, haha!all that definitely changes what i would recommend... i guess i would probably start with the "standard" 80 Hz crossover to start off with and then dial it in by ear with pink noise, and then some well-known tracks...
No!
Normally you'd want the sub to do the low stuff and the speakers to do the high stuff. There would be a relatively small range where both the sub and the speakers would play the same frequencies, and the 'blending' of that is the realm of magic...
The comment about the T5 not having a high pass filter on the rca outputs means that the echo will still get the entire frequency range to play, and with a high crossover set on the sub there will be a lot of overlap.

yeah, well it depends on your room layout etc. if, currently, your echo is in the same room as the rest of the setup and the room isn't huge, then yes. i would first try the main stereo setup with the sub, and you'll find you probably don't need another "satellite" speaker floating around the space.
but if you have a complex shape like an L or something where you need/want a satellite speaker to fill the whole space with music, then it's not necessarily the worst idea to use an echo for this imo.

but as @Mr Ee points out... there is still value in adding a sub to your overall setup. because, if set up correctly, then it allows your bookshelf/standmounts (or echo) to focus on what they are best at - mid and high range frequencies...
also, as he says - the lack of a HPF in the edifier would just make it a little bit harder to blend "magically" with the rest of your system. (+ it also wouldn't be able to "take the load off" the smaller speakers as i mentioned above)

@Mr Ee @BowsAndArrows Thank you for the further details and explanations. I have much to learn it seems.
Yes, that's exactly what we have and why we added the Echo. The layout is not ideal but it is what it is, and the Echo with the WiiM Mini in a permanent group with the Pro Plus and the main speakers has made a huge difference in improving the sound in the main listening area. So if I can get the T5s at a good price I'm hoping it will be all I need to complete the setup with some additional low end output.
I was going to get a WiiM Sound as a satellite speaker, but with its long release delay and expected high price here, the Mini and Echo turned out to be an excellent alternative for around AUD$160 combined in the last sales - much more affordable for me.

oh fair enough. that makes sense. well, in that case i would experiment with the placement and connections of the sub (i.e. choosing to hook it up to the pro plus vs the mini; moving around the room) - and probably just choose the most convenient location - cabling etc.
haven't seen it mentioned here, but, if you do end up going with the edifier (or another sub without HPF) you could try something like the FMODs in-line RCA high-pass filters? this would be basically like adding bass management to the edifiers but with the downside of having a fixed frequency setting.
if i were to guess which would sound better, then imo i would think that hooking up the sub in the pro plus stereo system + high passing your Q acoustics stereo speakers + keeping the mini/echo as is in the smaller section of the L-shape would give the best overall experience.
It may be easier or harder to understand if illustrated
This diagram shows the simulated frequency response of an Echo + Sub T5.
(I have simplified it here.)
This is the response when the Sub has no low-pass applied and is played back in full range.
The pink-filled area is the band where the Echo and Sub sounds overlap. This is the range where you can mainly hear, for example, the bass of drums.
Next, set the Sub low-pass filter to 60 Hz and you get this.
The low pass reduces the overlap of sound. Similarly, a high-pass set up on the main speakers can further reduce overlap.
This is a rough overview of high-pass and low-pass filters.
Currently it is not possible to apply a high-pass filter to the Echo, but one option is to use the equaliser in the Alexa app to lower the bass.
This is the frequency response of my Echo Dot.
As you can see above, turning Bass down to its minimum value will lower the frequency range below 80 Hz a little. You will get similar results with your Echo.
I recommend you run RoomFit with the equaliser on and off respectively, and compare the measurement results.
Thank you for taking the time to prepare these images. So overlap needs to be avoided, or is it not important?
Speaker driver units have different frequency ranges they are good at. Tweeter is good at reproducing high frequencies, midwoofer is good at reproducing mid frequencies and (sub)woofer is good at reproducing low frequencies.
Using a crossover filter cuts out the frequency bands that are not good for each driver unit, so that only the bands that it is good at can be reproduced. Yes, in my opinion it is important. But, it does not mean that the Echo's woofer necessarily needs a high-pass filter.
I assume your Q Acoustics speaker also have a high-pass filter on the tweeter and a low-pass filter on the woofer. However, some speakers don't have low-pass filter.
Ultimately, it's how your ears feel that matters most, so if you add a sub, experiment with different settings.
Btw, do you have room for another Echo? If possible, one way to do this is to try stereo with a combination of two Echos.
(I think you are now listening almost exclusively in mono..)
Well, as embarrassing as is it to say, I'm trying to do this as economically as possible, otherwise I would have opted for a WiiM Sub Pro and a WiiM Sound instead of the Echo and Mini, but I don't have a spare $1800.

i actually think you have a lot of options in your price range to complete your setup... and tbh the extra convenience/"cool" factors included in the WiiM products that necessitate a higher retail price might not suit everyone's needs. e.g. the screen on the WiiM sound imo is superfluous, and i don't know for sure obviously, but if the team had spent more of their budget/time/effort on sound alone then the end product would be quite different...Well, as embarrassing as is it to say, I'm trying to do this as economically as possible, otherwise I would have opted for a WiiM Sub Pro and a WiiM Sound instead of the Echo and Mini, but I don't have a spare $1800.
i mean i guess it does kinda look cool, but who really needs yet another screen to look at?to make my point more complete have you looked at other sub options in that price range like the Presonus Eris Sub 8BT?? admittedly it doesn't look as cool as the edifier T5s but it's got the added benefit of a high-pass filter + balanced I/O, and even wireless (BT) functionality - but i don't know how that works exactly. (another similar option would be the Mackie CR8S BT)
these are more geared to studio use, but by all accounts they perform pretty well for home/hi-fi use, and you can bet that the manufacturer spent more time on sound and functionality than aesthetics etc.
also keep in mind that we've come a LONG way in recent times, it's actually more cost-effective than ever to be into hi-fi i reckon. but still, if you hang around hi-fi forums long enough, spending racks of cash on random stuff just for fun can start to seem normal, even though it's actually not!

Looks like the team have already listened as there’s supposedly a screen free WiiM Sound Lite on the horizon, as mentioned at the UK Hifi Show this weekend.
