in short d3v have more low bass as the JBL 104 and esi unik 05+. the yamaha HS5 many youtuber have in their studio which is called have low Bass have most bass only below 40 hz . above 40 hz it have really low bass . position of speaker and microphone 75 cm to hearing position was same. i have it on desktop with a 25 cm stand

thats right speaker. diffrence happen because i can not place my desktop symmetric in room because L geometry room. treating i have ~18 qm but help not with measure results i try much diffrent placings. only decay time is shorter

now the 6.5 inch speakers in compare. only lower as 45 hz the 6.5 inch speaker rules, but they produce mud in lower mids 100-400 hz hear snare drum in audio testpiece. really great for a 3.5 inch speaker that produce no port noise. I think low bass of d3v really great, very often below 42 hz is not play important. kick drums are in range 50-70 hz so you get full punch with d3v and no nasty boom boy sound. sure the desktop have influence to this, but because d3v sound more better the problem is not desktop. speaker developers should not only test their speakers in a good room. they should do burst tests or at least test in not good rooms

the d3v with the passive membrane sound much better as all i have even if it have high level in 100-400 hz range. i like that currently i do not reduce it because clarity also with no EQ i think great and sound warmer. on headphones i like not reduce 100-400 hz because give strange feeling in ears, but on speaker in the past was important to get clarity.

in this thread you find more explain how the audio records are done, somw burst measure https://www.audiosciencereview.com/forum/index.php?threads/adam-audio-d3v-specs-price.57557/page-6

I forget the testpiece original in mono so can first left then right channel record. also good to do mono records with the left channel. I also have some audio records with listening position more near. can hear the more near the speakers the more realistic to original the sound get. in the example the 50 cm focal sound also better as with more distance but in real hear it is very hear position sensitive because of the large speaker and bass port. the d3v is really great at very near field. have a large sweet spot. both speakers give more low bass at shorter distance(because room mode have less influence) and go louder. so i think better is when place the speakers more near as 80 cm
