SVS SB-1000 Pro + Polk R100 bookshells : bass management questions

[daniboun]

Hi amigos,

Just got a pair of Polk R100 + a SVS SB-1000 Pro Sub.
Would like to know how to to optimize the integration of the SVS in my current living room
My amp is a Wiim Amp pro and my subwoofer is connected via the LFE plug.

My questions :

1) what would be the best configuration for the crossover frequency ?
I also used the auto setup to sync the SVS sub and my Polk R100s (https://faq.wiimhome.com/en/support/solutions/articles/72000629593)

2) I can use a 3 bands PEQ from the SVS application, do you have a suggestion or can you share a configuration already tested?
Actual settings are : Peq 1-freq 20hz - boost 6.0db - facteur q 3.0 / Peq 2.freq 23hz - boost -8,0db- facteur q 10,0. / Peq 3 -frq 20hz - boost 4.0db - facteur q 10.0.

On axis measurement for the R100 with EQ (what I did) is very nice

My actual living room is about 50M2

what would be the best configuration for the crossover frequency ?

There is no universally best crossover frequency.

Choose what fits your room and setup best, or simply what sounds best to your ears.

Fortunately, the WiiM Home App makes experimenting with crossover frequencies as easy as can be.

Suggested parameters depend entirely on your specific room modes.

Thanks for the response.
BTW since the SVS 100 pro has its own DSP and a digital crossover, do I have to bypass the one on the Wiim am pro? I mean this :

I would use 70hz to max 80hz (crossover) with one subwoofer and see what sounds best for you.

You mean you would bypass the crossover from the Wiim amp and use the one from SVS ?

I am only using the crossover (HPF) on my amplifier and some small PEQ settings on the SVS sub. The SVS sub only has a low pass filter.

Ok keep in mind I am using it in wide-band mode operation (LFE mode).

In the end, I'm having trouble knowing whether it's better to use SVS sub management via the Wiim amp or via the Android SVS app.
Could you please share me a screenshot of your SVS sub settings in the android app + your Wiim settings for the sub ? Thx

I would set the SB-1000 to LFE (all processing disabled) and use exclusively the WiiM crossover.

Will try thx )

Forgot to ask something and maybe you know....
I set some EQ presets from the SVS Android app. Do you know if I need to open the SVS app each time I want to use it or this is stored into the Sub memory ?

All DSP parameters configured in the App, are stored on the sub.

Ok so you confirm that if I don't use the SVS android application and therefore leave it closed when I launch Wiim Home, my SVS preset is kept in the Sub's memory?

Correct.

 

[daniboun]

Correct.

I carried out a first measurement test but I am not sure about the correct methodology : Maybe you can point me in the right direction...

Actual Settings, could you please help to correct ? :

Mic : iMM-6C Calibrated USB-C
Calibration file : OK (uploaded in RoomFit)

Target curve : Harman (what is the common one ?)
Frequency test : 20HZ to 20KHZ (full range makes sense with Sub?)
Max gain : 10db
Min gain -10db
Max Q : 8.5

No Boost mode : disable (may I enable it ?)
Sub calibration : Enabled
Smoothing: 1/6 (may I try another one ?)
Multiple measurements : enabled


Here first shoot with those settings :

Personally, I would run RoomFit using Moving Microphone Method without smoothing, restrict the correction to <400-500Hz and turn No boost mode on.

I want RoomFit to only remove constructive room modes, nothing else.

You can experiment with No boost mode off in case there are other bass response issues like early roll-off, just keep an eye out that RoomFit doesn't try to fill in destructive room modes ("nulls"), as that doesn't work.

Then, on top of this RoomFit correction, apply the PEQ preset found here ("Data & EQ" tab), which corrects the R100's anechoic response.

Target curve : Harman (what is the common one ?)

You may need to experiment to find what sounds best to you. I used the Harman target curve for a while, but it was too heavy handed in the bass in most good recordings, at least for my taste. I liked it better on older recordings mastered for vinyl. Now days I use a linear curve of -1dB/octave and tune 20Hz -300Hz on one room and tune 20Hz - 500Hz in the other room which has some issues in the 400Hz region.

I tried another approach by following the majority opinions on the Wiim Forum and combining your advice. I came up with this
@staticV3 > I added the PEQ Spinorama for the R100s a while ago.

That being said, I really prefer what I hear with the PEQ R100 Spinorama + PEQ Sub SVS and without the Roomfit.

Target curve : Harman

Once again:

Harman curve is not a target, it's a result.
Specifically is the rough result of a nice speaker in an average domestic room.
We should not aim for it.

Mandatory reading.

I think Wiim should be told to probably review their terminology)

Yep. Along with anyone else.
