Erin from Audio corner said they are the best desktop speakers hes heard.
the testers should measure distortion of bass port too.
such small speakers have allways a problem with Port noise when you EQ them to be linear. you need low bass EQ boost 9-12 db to get a noticable low bass, or you need use a subwoofer. I have JBL 104 4.5 inch , eris 3.5 3.5 inch and selled ilkmultimedia MTM 3.5 inch test and hear . the MTM was very expensive. I sell it soon because of the loud port noise. for example in this song at beginning with the low bass
I also own a Kali LP6 1(6.5 inch). the port design look same as the LP UNF. the LP6 have louder port noise in compare to esi unik 05+ (which is 5 inch) or focal alpha 65. (6.5 inch) but it is acceptable and better as the JBL 104 and eris 3.5.
when the speaker is put on desktop there can reduce 100-300 hz alot. See FR on desktop here
https://www.audiosciencereview.com/...dio-d3v-specs-price.57557/page-2#post-2111857 so you can low bass boost even more. and this even more also give you more port noise
I see in germany now on some shops can buy the d3v. I hope i get my D3v next week, then i can measure with arc 4 how they are compare to my other speakers and port noise.
If they have less Port noise is only theorie, only when hear can tell what happen. the passive woofers can also make noise or less transients. when want use a speaker on desktop, a klippel measure tell not much. I like more see a D3V measure in desktop.
I also measure the d3v when i have then on same place on diffrent angles with other speakers in compare if it happen that room modes get smaller because of the more membranes to side they have
currently i have with all my speakers the problem when i sit a little higher or a little more in front or back on chair, the room modes of left and right speakers differ and sound muddy and miss stereo localisation. So my hope is that this is better with the D3V . the larger speakers have this problem more the smaller speakers less. so the way to go is smaller to point source because i can also place them more near to ear. and the 15 degreee angle stand of the d3v is good to place them near.
