Sorry for the late updates. I know I've yet to update everyone on my finding or my journey with MiniDSP with lyngdorf. Some brothers pm me to know my journey as well. No worries, a brother just shared this with me & this is how ronildoq described previously (hopefully I'm not wrong) on time align subs together. I've uploaded the file in my drive.

Thank you rock123 & sorry once again brothers for the late response.

Yea very nice ! This is how I approach sub EQ and all other EQ now, I no longer look at frequency response, I look at timing. TIMING is the key essence and  holy grail for HT calibration . Get the timing right, all will fall into place, including the speakers, response etc

With other EQ programme, a lot of the group delays are set by the avr, with Lyngdorf u have to do it manually with mic and REW using acoustic timing reference. . This is the only thing we need to do on Lyngdorf before the room perfect EQ. Only after the above is done will you truly reap the full benefits of MP50

Finally, part of the journey is the end.... never been happier. I’ve come a Long way. To date, this is the best EQ I’ve done in years, in a living room, it can’t get any better than this

Below are the numbers from my rew measurements , compression test completed, with all 8 subwoofers measured at reference -10mv on LFE



The above will tell you that at 9hz reference levels, SPLs are hitting 114.8db, no compression.

Damn that gush of energy at 9hz... no fatigue at all, midbass continues to pound at 100db, it also tells u the house curve I’m using, a rising curve of 15db down to the Lowest frequency at 9hz , from 100hz. the above is with 8 woofers, 4 from seas 10” pushing with speed and Attack at midbass, supported by the depth from seatons , very clean sounding , the numbers don’t lie, can be confirmed with measurements below



Now look at the spectrogram above, at peak 115db 9hz, all bass decays from 35-100hz in less than 200ms, except for the one from 50-60, that’s not too bad, decays at less than 300ms. (Kitchen area, no choice) What this means is that frequencies in this range 50-60hz, stays on and linger slightly longer, the magic sauce here is the house curve and EQ methodology with timing, lower SPLs at 100hz. Remember this is 8 subwoofers placed at different locations in the living room. This is mighty impressive to me, and all 8 sums up with mains, surrounds and centre nicely. I didn’t bother verifying with Atmos speakers. I know it will sum after time alignment

The below numbers are the distortion figures at peak 115db, 13hz registering the highest distortion at 8.2%. It’s the second harmonics and the least audible and least offensive of distortions



The rest of the frequencies with distortions less than 1%, 9hz is about 4%, as can be seen from the graph. The one on Y axis is the %, the black line is the focus here for Total Harmonic Distortion. Maybe I can improve the resolution on the graph so folks can see better

This weekend, deep bass testing.... midbass passed ! Very very good, the balance is there now

Demo session starting 1st sept Sunday

2-5.30pm with close friends

1) NGSK
2) SDDS
3) Wechnivag
4) Ralfale
5) WIM

Wait for my friends to feedback, then, Next round demo again probably 3rd week sept, stay tuned. (It will be a Sunday 2-5pm) I’ll post the dates and reserve the slots for those who have requested and confirmed. Please bear with me, and don’t worry, I’m here to share

PS:// U will notice I didn’t bother posting frequencies response graph ;)

Testing completed, lone survivor gear up scene, a good continuous 30sec of SPLs at 132db 6hz .... 

Damn syok, feels as if u r in the chopper... intense... the average SPLs are good on this one

Oblivion sweep library scene is nice, u can see like a wave frequency moving from 100hz down to 20hz up down like a wave

The other one that I like below, real steel, twin boy scene, 122db at 10hz



Then tron legacy clip from reelwood demo



120db at 10hz, very syok

The sound is very balanced, less fatigue, not disturbing

I’ve also used a high shelf on the system, I enjoyed this better

Here is the filter I’m using






Stay tuned for next demo, I’ll list down, whoever can come, end sept19 Sunday. 3rd week of September can’t make it

Here is the video side of things, I use RTA to look at the levels,, with the mic placed beside MLP, to look at what frequencies these clips are playing

See this on lone Survivor, 6hz 132db !! Massive , this is where I love the seatons f18!

<a href="http://www.youtube.com/v/91NTN6fe2Cc&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/91NTN6fe2Cc&fs=1</a>

Next see the one on oblivion library scene, see the frequencies sweep from 100-20hz like a wave ... nice... most end at 20hz... that is why u see BEQ , bass Eq

<a href="http://www.youtube.com/v/OhJmSkKTTXw&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/OhJmSkKTTXw&fs=1</a>

The other impressive one that I like is the twin bot fighting scene with 123db at 10hz, lotsa lower midbass punches

<a href="http://www.youtube.com/v/5uMEohL_vbk&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/5uMEohL_vbk&fs=1</a>

Tron legacy race scene is also very good, didn’t need any BEQ, quite well balanced if u look at the spectrum

<a href="http://www.youtube.com/v/P-zyC2l2Onk&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/P-zyC2l2Onk&fs=1</a>

Last is the midbass scenes from true legend, if u watch the HK movies, they all focus on 30-70hz

<a href="http://www.youtube.com/v/oYz50fzYJac&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/oYz50fzYJac&fs=1</a>

All the Hollywood movies focus mainly below 30hz, the above were all played at -15 on MV on the lyngdorf, have the high shelf from 8000hz made things sound clearer on a lot of stuf, for movies, this is my preferred curve , attenuating higher frequency and bumping up lower frequencies

Unfortunately the session today had to be postponed as Daughter was suddenly infected with a gastro flu virus vomitting non stop.

Nonetheless, the demo will be done soon.

Yesterday I was testing BEQ (bass EQ) with the lyngdorf MP50, it can be done and you will not need a minidsp to sit in between.

I wanted to demo to the guys, the difference between a system that plays down to 20hz vs one that plays down to 6hz. The reasons for having an 18” subs that can dig down Low, and the Attack and speed it brings to the set up with a nicely time aligned system together with the quality of the entire system now.

Despite much longer wavelengths playing those single digits, the entire system feels “ extremely fast”, quite surprised. Again I will stress here, the key to all these is in the Time Domain.

Here is the difference between one with bass EQ and another without

Without bass EQ below



With bass EQ below





For the clip unbroken , it was amazing with so much details down lower frequencies. I’ve never heard unbroken sound that good before. Again the difference was felt , big difference with bass EQ on. You can see the average spectrum, very well balanced, good tonal balance as can be seen from 80hz down to 8hz. This is what sets this system apart from the rest, the ability to play clean deep bass down to the single digits without a Null and good time alignment. These graphs will tell you how good they are” not my good, not your good” , it’s measured using “ real time analysis” with REW

Next I tested another clip ready player one

Without bass EQ below




With bass eq below :





You can see a peak at 60hz, that scene is the beginning scene where the big truck like vehicle moves, the foley effects. You can also see that 20-30hz is very heavy with non bass EQ, feels too “meaty” (Kong and T. rex scene)

I prefer the one with bass EQ, u can see a much lowered 20-30hz , but better depth down 10-20hz, superb tonal balance

Boy oh boy, those single digit bass when hitting the body, brings about a “damn syok” feeling !

Despite the heavy SPLs, the separation, imaging and micro details are not masked out. There is no feeling of fatigue at all yet the bass is very very satisfying. A very nice decay on the upper frequencies, thanks to Room EQ Room Perfect, it’s just unbelievably good this room EQ.

This is the end game indeed.

I promised the guys this demo is something they will never forget...

Thanks desray, yea they were disappointed as it was indoor playground day for them today. Now all have to rest and 💤 at home...nonetheless, system is fully dialed in, ready for demo

Will host some demo and chat sessions moving forward so hope it will be a mutually beneficial session, there is always something to learn, something new...

Here is how you can enter the BEQ filters into Lyngdorf MP-50

First download the lyngdorf app from iTunes Store , then link it up with you mobile phone. Once linked, you can control your MP50 with the HP. Choose to on room perfect , different target curves etc, all with your mobile phone.

You can also use your browser on your hp, will look like this below







Head down to voicing, then use horizontal view on HP, input the BEQ filters into MP50 voicings

Example for men in Black below



Select filter, input under first filter, Low shelf Q 0.9 , gain 3.8, freq 10hz

Then 2 Low shelf filters -> With Q 1.1 , gain 4.6, 19hz
Parametric Eq ->40hz, Q 2, - 2.3 ( reduced meaty bass)
Parametric EQ-> 70hz Q=1, +0.6 gain

Master volume +1 from normal listening levels. If you are worried, play it at -15mv or -20mv, tons of headroom

Enjoy your movie after that. Much nicer tonal balance overall, very pleasant experience, tested and verified as can be seen above from the measurements

Interview with peter lyngdorf on 9th sept 19, look at Time stamp 7:12

<a href="http://www.youtube.com/v/qFQwXDowjRI&fs=1" target="_blank" class="new_win">http://www.youtube.com/v/qFQwXDowjRI&fs=1</a>

Exactly what I said in my post above on 23rd aug19. But he also didn’t mention what’s the focus and how it should be done , lol
