For comparison, the SVS SB-200 (cost £900, so twice as much) is around -4dB at 35Hz.

With a single SVS SB-1000 (older non-Pro) I'm able to get down to about 23Hz in-room at the listening position after PEQ - this it not even with corner placement:

This sub is discontinued officially, but is still often sold as "SVS SB-1000 Classic" for around 550€ in EU.
I'd be surprised if similar (or better) response couldn't be had with an SB-2000.
But I doubt the WiiM Sub Pro will reach this low in-room, even with corner-loading.

Sure it might not be relevant to everyone, but IME there are definitely tracks that benefit from really low bass (even those without church pipe organ ), not to mention movies.

Still, I 100% agree that in most cases the looks, ease of use and seamless integration of the Sub Pro will be more important to users than its limited low bass output capability.

For comparison, the SVS SB-200 (cost £900, so twice as much) is around -4dB at 35Hz.

In fairness, the SVS then sticks around down to c.-10dB at 20Hz whilst the WiiM plummets to -20dB or so.

In the second graph (with Room Fit) the WiiM is just under -5dB at 20Hz, but the aforementioned caveats apply.

Nonetheless, as I say for half the price of the SVS it's not at all bad.

I await Erin's review (I hope he does one).

Most recorded music has very little going at all, if anything, below 35Hz; I have a large polo mallet ready for the first person to mention large church pipe organs.

Try the live rendition of Eric Clapton's Layla and see if you detect the heavy foot stomping in a system that can't extend below 35Hz properly. See if you can feel the waves crashing ashore at the beginning of No More Blues with Dizzy on the French Riviera as they would were you right on that beach when your system doesn't really extend much beyond 35Hz. Can you feel the foot stomping on Andreas Vollenwewider's Dancing with the Lion without proper extension below 35Hz?

And can it do any of that at reference level if it doesn't flat much beyond 30Hz?

Sure, it's not going to be needed for 100% of the music like, say, 300Hz, but for the 10-15% of music that does contain information down that low, you'll be missing 100% of it.

On this I can fully agree-power is nothing without control.

I’ve been listening to a lot of new age stuff lately, and there’s a lot that gets way down there that you can’t fully appreciate unless you can feel it in your chest and all the way down your spinal cord (which is exactly why I’ve been listening to a lot of it!). I’d argue that depending on what you listen to, that number could be significantly higher than 10-15%. And yes, you’d be missing out on all of that with insufficient extension.

Yes, I think the key phrase is "...depending on what you listen to...".

Now, there you go. I believe Erin measures his outdoors - I've no idea where the chap in the video measured his.

It's important to compare like with like, I suppose.

By the way, I nearly bought a pair of M16s, but decided to save money with a pair of Wharfedale Diamond 12.1s, despite the 4dB dip at around 2kHz. I see you got the M16s...and the dip! Lovely speakers.

Yes, Erin does standard CTA-2010 measurement protocol, which is IMHO the most meaningful way to quantify subwoofer performance at the moment.

I agree!

They are very good for the price, IMHO, and so are Wharfedale Diamond 12.1!

The in-room response dip at ~2kHz is almost guarateed to happen with non-coaxial two-way loudspeakers, though.
It is a result of mainly the contribution of vertical off-axis sound at the listening position (floor and ceiling early reflections), and those will have a dip due to the drivers vertical offset and crossover.
As long as direct sound response is flat, the in-room response dip shouldn't be a cause for concern, IMO.

EDIT: In case of M16 the dip can be reduced a bit with some PEQ, without breaking the direct sound linearity, example:
