I have some conclusions but would really appreciate to know if they removed sound below 30hz that existed, or it never existed a anyway. Thanks

20Hz is so weird feeling at high volume.

You can confirm it produces sound at 20hz?

What about others?
post #6199 of 6599

The LCD2 have very, very low bass distortion.  You'll hardly hear anything at 20hz because it's mostly producing a clean 20hz.

Ah, sorry, no. Not on the LCD2. Was just browsing and hit that link. 

 

I'd be pretty surprised if you could hear it on the LCD2 because of the open back. At that frequency it's mostly pressure waves that you'd feel, not a tone you'd hear. On a closed back headphone that'll result in some pretty gnarly pressure sensations on the ear, but with an open back the energy will go outward and you won't get much from it.

Sorry, I don't have them anymore.

LCD-2.2, graphs posted earlier in thread. All three of the files produce clean audible and loud bass. The file below 20hz I can feel...and I can produce an audible beat frequency if I play a second audible tone from my speaker system. Even with the cutoff of the graph you posted (only 5db) you should hear these clearly.

well my fidelio X1 produces the shudder (boom, bass, etc) right down to 10Hz. but on my LCD-2: no shaking below 30Hz (there are the small pops but no shake).

 

hmm ....

Anyway here's my theory. It's pretty clear they have chopped off the very bottom under 30hz to make room for the top end. Perhaps thinking that every person won't ever want to feel anything that deep.

My early 2014 LCD-2 certainly produces 20Hz, though the volume is a bit recessed from 30Hz (which my graph supports). So, I find I have to turn up the volume to get the obtain a similar sound pressure level as 30Hz. I get no pops whatsoever, just a clean sensation of fluctuating pressure.

Certainly a possibility; a tuning tweak is my suspicion...looking forward to Tyll's comments on this. I've noticed that a number of the late 2013 to 2014 graphs don't show a perfectly linear low-end like the earlier versions did.

apologies i was playing the wrong file (i have many test files) - playing the files i uploaded produced 'sound' right down to about 12-13Hz. but definitely much softer under 30Hz.

 

shall we call it the LCD 2.5 since it's halfway to a 3 presumably LOL

post #6207 of 6599

Graphs from late-ish 2013 (Sept and oct) seem to have both the high-end energy and flat subbass.

 

Here's my graph.

 

post #6208 of 6599

whereas mine is a full 15dB between 4kHz and 40Hz and 12dB between 4kHz and 12kHz

 

definitely much unveiled almost sparkly treble. i seriously have heard stuff i never heard before at the top end, but without annoying. (i almost died testing dt 990 pro 250 - i am 100% intolerant to sibilance)

post #6209 of 6599
Just for comparison, here's my LCD-3 graph from 11-6-2013.

So

Is there anyone using graham slee ultra linear? (From UK)

smily_headphones1.gif

just noticed this post

sorry

I used the combo lcd2.2+graham ulde till a couple of months ago

very nice sound but I felt something missing too

so I "upgraded" to a burson conductor

that for sure as more juicy of the ulde, and you can feel immediately

but the graham sound better..less grainy and more linear and dark separation, and I prefer the size of the graham as well

I guess the ulde with the lcd X should be amazing

pay attention to the dac, I used a concero hd that missed a bit of detail

much better the dac inside the burson, but again: very grainy and noisy form the usb port

right now I m listening audeze/conductor using the concero hd as converter

and it s wonderful
