Room correction

[m_sherzod]

The external microphone is not a requirement to implement the updated Room Correction. I've used an iPhone and an iPad but dug out an external Shure microphone I had bought some years back for $80. It seemed to do the best connected to an old iPad so I kept one setting that way and another on the iPhone on the earlier WiiM RC.

(Depending on the iPhone version, it may allow an external jack connection for an external mic or another method using a different microphone connector. The WiiM RC is designed to allow for using the internal iPhone microphone so no reason not to use it.)

In my highly sensitive monoblock tube system, this dual RC is a significant system improvement. I'm tremendously impressed with the results in my room. (i've also cheated with the original WiiM Pro using a 5v external power supply and Cisco ethernet boxes running fiber from a fiber optic router. One helleva bang with this WiiM RC update.)

Really happy for you!

If you are interested, please find and play this track; it is available on Amazon music, Spotify, and YouTube music.

This tone signal starts at 110 Hz and goes down by 10 Hz. If this sounds smooth at the listening position, the 67Hz dip may not be a big problem.

This was measured at the listening position in my room (3m*4m). My ears can hear a slight dip at 70Hz, but overall it sounds smooth. 30Hz seems a little louder. (Note that the 100Hz area is boosted for my taste.)

And this was measured with the mic at a point 50 cm right in front of my ear; you can see the 70 Hz dip is getting deeper and wider. Just moving the listening position a little changes it in no small way.

In case you are wondering, this is in the tiny bathroom next to the room

It looks like we have similar sized rooms. )) Definitely will try this track and come back. What speakers do you use and do you have a sub?

 

[m_sherzod]

It might be possible to improve this by putting sound absorbing material on the wall behind the seats, but I won't know until try..




Yes.
I think you need to find an appropriate place for the sub.

I have ordered these cheap Chinese corner bass traps to put on the wall corners behind the speakers. Should arrive early January. Will see what happens)

KEF R3 Meta and 2 Subs (polk ES10SW) driven by 2 WiiMs.



The wall diffusion panels were purchased cheaply from China .

If not enough, it can be placed in only 8 corners.



Good luck .

Wow, nice setup! So I assume the subs did not solve the issue with dip?(

I have done the R/L separate RC, and it seems the dip has gone. Thanks)

No, it has improved a lot. It used to be much worse.

Thanks
Your AV room is also very nice.

But now there's a massive +9 dB hump around 80 Hz. Doesn't look too good to me.

Yeah, when I tried some tracks the bass was out of control..((

Try limiting the max frequency for RC to 400 or 500Hz.

Those won’t do anything for low frequencies unfortunately. You need actual panels and real bass traps. Go to gikacoustics.com to get an idea of the types of room treatment ideas that will work for your specific needs. Slapping cheap foam on your wall will just look cheap. I’ve been there.

But the problem is in lower frequencies, you think that might help?

Thanks for the advice)

30-400Hz includes the lower frequencies and allows 10 PEQ filters to cover that range. It might improve the response and remove that hump at 80Hz.

Thanks. Should I do the L&R separate RC or the standard one?

You can do no both and see which you prefer.

 

[amix]

at least in an asymmetrical room.

It's also better in a symmetric one. Because, total symmetry rarely exists in a room. Bookshelves, etc.

Yes. So I really, really wish this can be implemented with subwoofer/bass management enabled.
