Lyngdorf discussion

I'm looking at both of those to replace my old projector cable, which mostly works w/4k, but not always.

Got a link?
I use the monoprice slim run av myself. Both of these brands confirmed working flawlessly with Lyngdorf and JVC products.

Hi. Never had and a proper hi-fi sistem, let alone a room sound correction device. I am curios how the Room Perfect works. Did he enhance the sound only in the sweet spot, in the area you take measurements with the microphone or in all room? I don't quite like to sit put in the sweet spot and listen to music. Most of the times when I listen music I am moving around the room doing things and I am wondering if it worth to buy a Lyngdorf or I will be fine without room correction. Thank you.

Is does all that, but within the borders of physical limitations. The more subwoofers and speakers you use, the better it will be to have good sound on your sweet spot and all the other places in your room.

Never had this before....
Added LFE to the rest of the speakers, now normally message pops up saying "you must re run Roomperfect" and you loose the Focus and Global RP. This is normal.

Now adding the LFE after the 3.6.1 update all worked without having to re run RP 😮
(Not saying you now don't need to run RP after adjusting any speaker settings) you should, but never seen this before.

Anyone else notice this?

Why or even how, are you putting LFE into the regular speakers? LFE is the subwoofer FX channel.

1st position is the FOCUS position there after the more random you move the mic around the room the better info Roomperfect has on the room.

After 95% you can move the mic .5m away from walls and ceiling.

After running RP you can change FOCUS to GLOBAL this would I think work well for you as you are not always in the main listening seat.

I'm not ROCK? I'm adding LFE to the system

It just surprised me after quitting the menu screen the RP light was still lit up, normally after adding a speaker or changing the Xovers you loose RP until you re run it.

You have 2 subs tho right or 4? Regardless any change you make to the speaker config will prompt a rerun of RP, always been that way. LFE is a single sub deal unless you're doing 2x AUX and 2x LFE?

There is an MP50 on eBay from Germany which has the new HDMI board

Yes any changes would always prompt to re run RP, but also would disconnect RP until you re run it.
But now it seems you can make a change to the speaker configuration and NOT disconnect RP, I've never seen this with the old software.

I think once you add say LFE and hit save then boom it's all gone - not sure if it's always been like that or not, but that's why we have backups I guess? If it's different now then I dunno..

Sorry was just trying to work out if it was me orbits a real part of the update 🤪

It's the only negative of RP that you can't make a change to evaluate first before running RP.

As you were..

I’ve moved some stuff about in my room and I’m going to do a new RP calibration. My seating position is right up against the rear wall (no way to do anything about that), so that my head is about 1’ from the wall when I’m sat there listening. Before running RP there was a pronounced change in the sound if I leant forward even by another ft, where the soundstage would become much more 3 dimensional, and much flatter when seated normally. RP has done an excellent job mitigating this effect but it cannot do so entirely.

Would it be advisable to take my first measurement with the microphone a bit further forward than where my head would normally be? Then also one of my >95% measurements could be right near the rear wall behind my seat. Would this successfully add a little additional compensation for the wall being so close behind me, or am I likely to cause more problems than I solve by trying to outsmart RP?

Are you able at all to move the sofa 1' forward?

I would put the mic exactly where you're head will be.
But possibly I would take more measurements around that area, problem for you is the mic should be no more than .5m from walls.

I would take first focus position as normal then random positions around the room, then take one in the focus position again but mic pointing down to the sofa or left and right of focus position. Do this after 95%

If you haven't already I'd put something acoustically absorbent on the wall behind your head.

Only like 30cm thick absorption will do the trick. RP, nor any DSP, can fix the effects of a wall directly behind your listening position.

Not so.

From http://www.acoustic.ua/st/web_absorption_data_eng.pdf

ABSORPTION COEFFICIENTS for Flexible polyurethane foam 50mm
FREQUENCY Hz
125 250 500 1000 2000 4000
0,25 0,50 0,85 0,95 0,90 0,90

This would help substantially with the primary 1/4 wavelength wall bounce suckout, and clean up imaging issues from higher freq reflections which will be almost completely absorbed.

I really can’t move it. It would just look odd and even if i could live with it, the boss couldn’t. It’s our lounge and it’s a 4*4m room, so not that big.

I’ll try what you suggest with the additional measurements. Thanks.

Thanks, I’ll check that out.

upgraded my fuses in the wall.... 😘
I have always said that I love hifi porn. Exotic cables, speakers, weird add on things and boutique record players - I got to see a fair bit of it when I worked in that era.

At the same time playing, recording and mixing music kept me grounded. There are some absolute dogsh*t cables out there, not to mention the internal wiring and connectors of speaker cabinets and amps, so I use decent cables. It was only recently that an ordinary old yet high speed hdmi cable was able to crash the entire video stage of my MP60.

I also came across a video on YouTube about the very subtle differences in the ruipro and monoprice hdmi fibre cables, worth a watch.
It is so interesting that i some ways you and i are very close in gear and previous jobs 😁. I have been working in music production and sound design for film for 25 years, so i know where you are coming from on cables 😁. ill guess there is something about the lyngdorf feature set, as well as the M&K stuff that resonates and feel safe and trustworthy to us?

BTW I use long SCP fibre HDMI cables. They are smarter than the RUIPRO that might be basicly the same, but without the ability to take the hdmi plug apart for easy pulling.

I was talking about low frequencies.

You cannot EQ bass problems created by the back wall when your head is just a foot away from it. And there will always be problems with this situation. And you are right, for low/bass (up to 100 orso Hz) frequencies it can be allright, but not for low/mid frequencies. For solving mid frequencies you'll need lots of absorption.

200Hz (mid/low) needs 43 cm of absorption.
