Wiim Sub Pro

Harmonics below the note?

Also it's not necessarily true that an instrument playing a 20Hz "note" will have a dominant fundamental. For example, most any piano, especially if it's not a full size concert grand, will have the harmonics dominant for much of the lowest bass register as the strings are not long enough. Instead they are thickened to get the note lower but this results in a lot of harmonics, particularly of note on smaller grands and uprights where the bass notes can often sound pretty muddy due to this. Physics is not just a bitch for speakers, it applies just as well to instruments.

I was replying to a post which suggested just that.

The harmonic resonances are FELT in the body, even if "infra" sonic.

OK TIL that "harmonics" are only at higher frequencies.

To rephrase:

The infrasonic resonances are FELT in the body, but all the equipment in the chain needs to be designed to record and transmit those signals, in order for such a large / powerful amp+sub to have any chance of reproducing them.

Getting away from film LFE and only for music, such recordings are very rare, so perhaps not worth the effort.

Getting high SPL down below 30Hz is already hard / expensive enough for most ordinary folk.

Accurate?

Thanks for clarifying, even if the answer was given to another member: is more or less what I considered as a sweat spot to my sub: I only want to use It for music and I prefer less vibrations in the floor and walls to prevent disturbing my neighbours.

There are some measurements published in YouTube for the WiiM Sub, It has a smooth roll-off from 40 Hz down to 20 Hz, reaching a máximum SPL of 70 dB at 25 Hz.

Possibly is enough to reinforce my couple of G Threes in the 40 Hz región, without spending too much or making enemies among my neighbours...

I actually have a Kali WS 6.2 in returning process, because high noise audible at 4 m, It seems barely all units have the same issue in LFE and external mode.

Could the WiiM Sub Pro be a good candidate for jazz, classical and rock (not heavy, black metal...)?

My room is 5 x 3 meters, listening position at 2 m

Other possibility is SVS 3000 micro, or even SVS 1000 Pro

 

[john61ct]

SVS 3000 would likely have MUCH more impact. SVS 1000 Pro also has a stellar rep, relative to its size and price, this is such a new product will be a roll of the dice

really, there is no substitute for YOU listening, in your system, in your room.

The main point of getting a Wiim accessory would be the over-network integration into the Wiim ecosystem.

In my actual office, this can be an advantage since frequently I should change objects to make place for exercises (I’m physiotherapist).

I red some comments about the difficulty of sub integration via WIFI, but they don’t specify what are the potential problems.

I’m tempted of abuse a little bit of the 14 days of reflexion period and try one of those, the SVS 3000 micro is 400€ above and the 1000 Pro has an unprotected woofer that could be damaged during exercises.

 

[john61ct]

not abuse, that is the whole point of buying from sources easy to return, they WANT people to try and listen!

Network in my case means wired ethernet, I do not trust WiFi much more than BT for streaming the music content, only for control signaling

Tanks for the ethic point of view.

I ran my WiiM Ultra wirelessly since 1 year, apart from minor issues (when I use Qobuz connect, so due to the app integration with WiiM) never had a problem.

Even in the crazy 24/192 kHz tracks (who needs that?), 10 Mpbs are enough bandwidth, I have a stable 150-200 Mbps connection.

As I red in the forums, WiiM Sub streams directly from the same network than the WiiM, they don’t use protocols as AirPlay or similar to emit from one device to the other.

I took one for the team and have my Wiim Pro Sub running as I type. My hair is standing on end vibrating with the massive pressure wave in my living room as I navigate my playlists.

Ok not really . When it came yesterday I connected it to my Wiim Amp Ultra which runs my Linton 85s. I didn't notice a lot of difference as I went through a playlist of songs would get the sub going. Nope nada. So I ran some test tones and found my Lintons put out more energy at 35hz than the Wiin sub pro. It shouldn't be a big surprise. The linton has two 8's and are physically larger than the sub. I ran the the roomful dsp and it looked the sub was getting to around 35hz before petering off. But I didn't buy the wiim sub pro to run with the Lintons and this was the outcome I expected. Moral of the story, this sub isn't going to add much to your full range tower speakers.

I bought the sub to go with my desktop setup. I am running a USB out of my MacBook to an NAD 3020 class D amp running a set of Kef LS/50. Then the sub out is sending the signal to the wiim sub pro. The sub will do wireless with the Wiim amp ultra but not with 3rd party systems. It took me a bit to get sounding good. The 3020 does a high pass when a sub is connect but the information on that is a little vague. I ended up plugging the ports and that cleaned things up well. I didn't feel the need to eq...

I ran the sub up to 90hz which is slightly above the LS50 rolloff. I purposely placed the amp in the corner next to my desk to boost the low frequency content and then used roomful dsp to knock down a peak around 50hz. In the corner I get a little more extension to around 32hz but not the 25hz (edit: I moved the sub a small amount, reran roomfit and I am getting flat to 30hz and 3db down in the high 20's!!!) wiim was able to achieve. To integrate with the power of the 3030 I needed to take the sub down 6db. So how does the sub sound!

Awesome! with everything blending well the sub sounds great. I put on bass heavy music like Primus and let her rip. Damn! Now caveat this with the fact with this near field arrangement the sub doesn't have to work too hard but cranking it up, it does a fair bit better and reproducing kick drums, bass guitar/stand up bass and keeps up with the music without sounding strained at all. It is more impressive than my Linton's without subs and that is also sitting pretty close to the Lintons and they are also pretty close to the back wall. In fact it sounds like being in the front row of the rock concert. This system absolutely rocks using the Wiim Sub Pro. The bass is tight, not boomy, and gets the kick drum and bass content right. My son is a drummer (he is 17) so I asked him to come listen. He rolled his eyes because he was occupied playing a new video game. He sat down reluctantly and conjured up some metal. The sub danced through his selections with a muscular presentation. He sat there for at least a half hour going through his playlists with a big grin. He said he heard things he never heard. Getting things to sound right in a room can be a challenge but the wiim sub pro helped make it happen.

This is niche product. It is beautifully built, not overly large, and has DSP. If the application fits the capabilities if the sub I would consider it for sure. I bought it on a flash sale for $380.00 and for that I am extremely pleased.

That's ver interesting. On the one hand, it goes down flat to 30Hz, absolutely no drop off at all, which is excellent for a box this size. But then it takes a noze dive of -20dB at 20Hz, which is pretty steep. So that's lower than I expected, but also a steeper drop off than I expected.

Thanks for sharing.

I wonder if that is by design? I can see them filtering that to keep people from destroying the driver using it for HT. But still, I am getting to the upper 20's and that is plenty for my music needs and probably for music listening for most.

 

[gasolin75]

When i have my wiim ultra streamer at 100%,fixed volume, since the amp has a smoother volume when you use it (theres is a resistance from the volume knob on the ultra streamer), is is possible to use a subwoofer ?

Theres no volume up and down from the streamer other than volume of the music,recordings

Yes, but you'd have to find a subwoofer with Speaker level input, that is also compatible with Class D Amps.

And you'd lose all the Sub integration features of the WiiM Ultra.

You may know but in the Wiim app you can adjust the volume control behavior.

But how is it adjusted ?

Down to 30hz or 20 hz when doing room fit ?

When using room fit, the app will show what the frequency response is in your room. In mine it is flat to 30hz. The steep drop off, I believe is dsp controlled. After room fit is complete you can go into the new fit profile and edit the eq which I have not done. But you could bump 20hz if you wanted. I did not.

 

[StephenMarkLay]

How ?

I the wiim app, scroll down the device menu towards the bottom. You should see "Knob Volume step"

 

[gasolin75]

you can't evaluate,measure the frequency before room fit

How it adjust the frequency depend on your settings

 

[gasolin75]

What would that do for me ?

(Fixed Volume (Recommended for Quality): Sets the WiiM output to 100% (bit-perfect) and uses your amplifier to control volume.)

I have a WiiM Ultra too, you won't notice any quality lost by using variable volume (is just for SPDIF), and you need headroom for equalization.

Perhaps I didn't understood well what you wanted to do, but you can adjust independently the sub volume by +15 dB to - 15 dB in the sub output settings.
