WiiM Sub Pro – 8" 250 W Wireless Smart Subwoofer | AI RoomFit™ Calibration | Wi-Fi 6 & Bluetooth 5.3 | 25 Hz Deep Bass | Works with WiiM-Streamers, Amps & Any RCA Sub-Out System


If my line of credit had enough available I'd have it shipped to be tested.

I suspect 8" is not enough to really stand alone but I'm sure would really help my setup.

My main questions: how HIGH a frequency range do they cover and at what max SPL safely?

to match my OG LS50s safe max once high pass filtered - 150, 250?
 
Really I want DC powered for off grid use, but "inquiring minds want to know"

Thanks, 25–200 Hz (±3 dB from 30–200Hz)

but the SPL claim may not turn out to be true.

What I meant was, once members have the device, I'm looking for answers from experience and measurements, and hopefully one day someone (with deeper pockets than I) will be willing to have one shipped to Amir.
 
Hmmm, hadn't seen this before since I don't pay close attention to the Wiim community (despite somehow having ended up with 5 Wiim devices). $449 is slightly higher than my 'no brainer' threshold given that I have lots of parts available to DIY a solution, but I'm likely to cave as I have an almost perfect application for this paired with a Wiim Amp Pro in the living room as it will tuck relatively inconspicuously under the end table.
 
Amazon website says 'currenty unavailable'. Anybody know any other sellers?

There are no distortion measurements so not worth much as you say. 8" driver and 250W amp does not seem to promise much though.

Wireless? Good that it has RCA input as the wireless subs are tricky.

But at least pretty one as much as subs are.

My feeling is that this has to be viewed as filling the same role as a Sonos sub or similar - it's really a 'woofer module' augmentation for bookshelf speakers. It's not a subwoofer for the dedicated HT crowd or the 'high output' main system. I've run 8" subs in this type of application before, and they work quite well.

Could be.

But why would you want to integrate a sub, which is a headache, when tower with 2x8" passive drivers could probably get you to the same place? Can't really say as did not listen to this sub though. Integration for the towers is already done, for better or worse, depending on the model you choose.

You even don't have to get a stand for bookshelves with the towers?
 
Some living spaces (or spouses) require small form factors. For me this is at the largish end of what I want, besides the AC power issue.

The Amazon stock ran out a few hours after the release announcement, maybe a higher initial demand than Wiim expected?

Better IMO to be patient, rather than ordering from unvetted suppliers.

Yeah, guess I have to be explicit:
Not all systems where you may want some bass enhancement are formal dedicated high-end systems. There are a LOT of cases where you're setting up systems in living spaces where you don't have complete freedom of choice in speaker location, size etc. This type of 'woofer module' plays into that category - where you're using small speakers for placement or aesthetic reasons, and being able to add a not-ugly sub to fill out the bottom end can be a big improvement, and the wireless ability is just icing on the cake - running wires across the room can be a big headache.

So, not a product that is aimed to those looking for a subwoofer for HT duties or to cover the 20-40 range below larger floor standers. But one that can definitely enhance more casual systems.
 
So this is my question.

An 8" driver seems a bit small, but that's not the whole story. I mean the drivers in your IEMs can go down to 20Hz, just not very loud (in loudspeaker terms).

So okay, let's take it as being able to go down to 25Hz, the question then is, how loud and at what level of distortion? WiiM's original press release said "250W of deep, clean bass with less than 1% THD+N."

So here's my question. Yes an 8" driver can get you 25Hz at <1% THD, but how loud could such a device possibly go? I listen in a small-medium room (5m x 3m) at fairly close distance (c.1.5m from the sub), and I don't listen to music at ear-bleeding levels. I'm guessing 86dB? So could this potentially do 25Hz at 1% THD at 86dB?

That's about the limit of what you should expect from the WiiM Sub.

Okay, I've just watched the video. At the end he seems to say you can get down to 30-35Hz at 94dB. If WiiM are using EQ to flatten that out, and don't go above say 86dB, then we're almost-not-quite-sorta-ballpark.

The one thing I noticed straight away was the price difference, Monoprice's $210 vs the WiiM's $450. How much more can that $240 + WiiM's EQ know-how get you, I wonder?

Well, Erin does like to review subs from time-to-time, and reviews most things WiiM releases, and pretty quickly. We'll see soon enough.

Sure, but that's if you're not expecting there to be any transients that are significantly louder than that in your content. I find that unlikely. You need some headroom, you don't want to be topped out at the average SPL.

Even if you're not being demanding, I think you're expecting too much from an 8" driver in a small enclosure. Especially considering the amp isn't even that powerful. Chasing sub-30Hz performance in these small subs is a fool's errand, IMO. You're sacrificing performance in the more critical sub frequencies for really poor performance in the lowest frequencies.
 
Looks like an interesting product and the perfect solution for my Wiim Amp + Q150 setup which is currently missing that bass oomph but I’m not expecting thunderous power (my windows already rattle at 86dB 4m distance).

The price is quite a bit higher than I’m comfortable shelling out without a second thought, especially when the speedwoofer 10e exists.

Guess it all depends on the actual performance of this little sub but I’m not holding my breath.
