How to set up roomfit correctly? help

[dominikz]

Surely KEF LS50 should play lower than 100Hz in room.

I'm sure they can - IMHO the problem here is SBIR - most likely from the side wall, but possibly also from ceiling/floor reflection.

I can see what is happening, i realise with phone + mic, i can move myself instead of the speakers!

so i moved myself all the way back to my display shelf, and it seems to reduced the sub problem! the placements science! I never thought that much of it, over WAF!

the speakers dip remains, sadly i dont have space to move them, maybe they are damaged

If it's boosting just to sort out the problem, you really don't want to do that. Pushing the drivers harder, and those Kef metal drivers do not tolerate abuse.

so is better to turn off roomfit seeing my results?

No, just don't allow it to apply any boosting. There is option to only apply cuts, it's called "no boost option" or something like that.

You don't want to push your drivers hard modern Kef woofers are pretty fragile

Have you tried increasing the crossover to 110Hz?

I tried, it has minimal changes in the roomfit results
but playing back music, i think the integration sounded better?

Increase the sub volume in the WiiM app and run Roomfit again and post the frequency response here.

Yeah ... it's this one single pic on a merry-go-round through the Internet. This simply doesn't happen, but on purpose.

For sure they can. Here is the pair in my bedroom, 7 cm from the front wall, no subwoofer.

No EQ.

Also there's no real RoomFit correction (frequency range 9.4 kHz to 20 kHz, min/max gain +/-0.5 dB, max Q 10, non-boost mode). I just "abused" RoomFit for a quick measurement to show how low the LS50 can go in-room.

This certainly looks a lot better to me.

If you cannot move the speakers and the sub, that's what it is. The entire setup will be relatively sensitive to small variations of the MLP.

Actually, optimizing placement is one of the biggest upgrades for sound quality you can make - and it is free.
Next is optimal subwoofer integration (crossover frequency, level, polarity and delay) and EQ/room correction.

This is where really big improvements can be had, so it is IMHO really worth it to spend time to do it right. It may be a bit tedious, but you only need to do it once.

RoomFit correction at this high frequency?

 

[rccarguy]

RoomFit correction at this high frequency?

Typically it's best NOT to do full range correction, I stop at around 300-400hz, Anthem use 1khz or 4khz I forget which

Notice you have fair bit of high end roll off, try different toe in angle, try with the drivers firing right at you. That might increase the high end a bit.

Do you guys ever read before you post?
@Gurkensepp? @rccarguy?

Or do you just look at pretty pictures.

Exactly. Drives me mad sometimes
