That because the vent releases pressure in the opposite phase. You are feeding the inverted phase signal into positive signal canceling portion of frequency, obviously the result is lower SPL and added distortion.
I bought a single sonion 2389 from them to replace the one I lost, and I couldn’t hear any difference between it and another 2389 I had. I also got a couple of the 38D1XJ sub drivers and put them in another set I’m working on, and they definitely have that subwoofer in your head thing going on, so I’m guessing they’re all legit.
Nice then. Thanks for the info. Seems legit.
It could be an artifact form the sound card. In general anything below 20Hz you can disregard.Just repaired a tube leak on my tribrid, now to fix the other side. Has anybody seen something else with an upward curve on the low end like this?
The IEM nerd inside me is jelly!From "Alsilence" aliex store, received in 10 calendar days to the US. Labeled well, safely packed, pretty big 3d printed shells for 9 bucks.
Edit: related aliexpress note, KZ PR2 (13.2mm planar) are VERY cheap right now
Edit again, almost a full IEM here at this point, busy day. The eBay gods have smiled upon me. I guess I'm switching to metal film resistors, I know a sign when I see one. 1/4 watt 1% qty.10 each, about 0.4 ohm increments 10-100ohm, values I did not think existed. I have a few IEMs with external crossovers so I can rebuild them and measure some A/B comparisons. I can't imagine the time it took to put this collection together, so thank you to somebody out there.
Im honestly supremely disappointed in Knowles being so “violated” by Bellsing that they sued another multinational corporation and named 3 or 4 well know companies as part of the suit. Then they win! Get their verdict. With a WIDE open armature market, what do they do? Constrict tighter and raise prices on legacy products. Why market the “new industry changing” products to the general public when you have zero desire or plan to help the smaller guys. Im just salty That as a US citizen and resident, I can purchase said American company’s products from a supplier on the other side of the planet and get it delivered quicker and at half the price than the Mouser’s and Digi’s of the world. Seltech,God bless’em for trying, but its a stupid mess. Rant over.
@mattmatt to answer your question on RDI. Mouser and Digi wont stock them and require a 100 piece minimum I believe. Which, also endearingly almost always includes a 6-8 week lead time. Seltech usually has availability, but their purchase minimums are built on the whims of a whatever sales person picks up the phone, if they even do that.
In my personal opinion, here's the thing, Knowles is a huge company (700M$ reported revenue for 2023, 1.4B$ in assets LINK) and funnily enough I think Balanced Armatures are their smallest share of profits.
oh wow, that I didn't know of, that BAs are small portion of their company. Just wondering to if there's a place that the RDI can be purchased in a not so huge quantities? If not, what good dual woofers can match it?
I thought you had a good relationship with Seltech?
