Bass Management Options

[Mp0wer]

Hello

I’m curious if we can get an option to set the high pass and low pass separately and also be able to set the crossover slope independently too.

Also does anyone know what the crossover slope is used for the subwoofer output and Line level output ?

The next development step regarding bass management, which has already been announced, is the ability to disable either the high pass filter for the mains or the low pass filter for the sub. Personally, I don't think that this is really of much use.

The current setup provides 24 dB/octave 4th order Linkwitz/Riley filters for high pass and low pass and one common crossover frequency, of course. While this approach offers somewhat limit flexibility it is still the best option in the vast majority of cases.

I agree that having full and independent control over the crossover frequency and filter type and slope would be a nice addition for advanced users. My Lyngdorf amp offers just that ... but also for me the default of LR4 and a common crossover setting turned out to work best. Your request would be far more useful than just skipping HP or LP. If I was in WiiM's shoes I wouldn't even care about bypassing the filters. But I would probably still assign a rather low priority to your request.

To sum it up, in principle I am with you and I will support this request. But I don't think it is essential and not that helpful (might even be potentially irritating) for the typical user.

+1 a million times.

Ìve been into sub sat setups forever and still the best result is sealed sat to be crossed over at it‘s minus 3db point by adding a 12db Butterworth highpass at the same frequency. The sub will get a 24dB Linkwitz rilley and you will have a perfect in phase crossover delayed by 1 cycle (LR textbook)

People do not realize how much pain the 180° phase shift towards the satelite’s port tuning frequency is. One of the main issues why Sub integration fail.

Ken Kreisel, PeterLyngdorf, THX and lately Perlisten know about the advantages. Thats what makes their bass „thight and fast“

Would probably easy for WIIM to integrate and make a big step forward in potential SQ

Hey, where can i find this? Curious to read it Thank you. (Just realized that this is an old post :/ )

Old, indeed. Doesn't hurt too much in this case.

The settings are found in device settings, Sub Out. Sub Output must be enabled.
Subwoofer Bypass Mode: No low pass filter is applied to the subwoofer mono output
Main Speakers Output Bass: No high pass filter is applied to the WiiM devices stereo output

It's generally preferable to not enable these settings and leave the crossover between WiiM device and sub to the precise 4th order Linkwitz-Riley filter built into the WiiM. In some special cases these settings could still be useful to obtain the best possible subwoofer integration.

Hello, can anyone tell me if I can use the Wiim Pro Plus with two Wiim Sub Pros and calibrate them, since two subwoofers make more sense than one in my room? Thanks in advance.

Don’t believe that’s possible - it was asked previously but not sure if WiiM said it was something they might consider.

OK, that sounds great, but can't you connect the Wiim Sub Pro wirelessly to any Wiim device? (That's how Wiim describes it.) My question is, can you use two at the same time?

Unfortunately, I can't test it yet, as the Sub isn't available in Germany yet.

Best regards, Daniel

The WiiM Team has responded as follows.

"For stereo setups with two streamers, multiple Sub Pros can be paired as well."

This suggests that only one Sub Pro can be paired with a single WiiM device.
However, I guess that linking two Pro Plus units as a stereo pair within a multi-room group means you can connect two Sub Pro units.

If you'd like more details, I recommend submitting a ticket via the feedback section in the WiiM app.

Does this mean Pro, Pro+, mini will have bass management capability (lowpass / highpass filter, and time alignment) when connected with Sub Pro?

Hi jed1, team

Exactly! You can wirelessly pair the WiiM Mini, Pro, or Pro Plus with the WiiM Sub Pro, which handles bass management just like a wired sub-out connection. For stereo setups with two streamers, multiple Sub Pros can be paired as well. The WiiM Home App supports automatic calibration for time alignment and room EQ, giving you flexible control and customization options.
