A little bit off topic, but do you have a database/site of your other reviews @Nuyes ? Do you produce Spinorama/CEA2034 datasets?
The exact cause was unknown.I’m a little confused on what the major issue was found to be? Was it lack of absorption material or the enclosure leakage?
Sample B also had the binding post exposed.
Alan claims this was a QC mistake, but if so, did he 'mistake' the QC of two speakers in a row?
Enclosure leakage mainly through the binding post appears to be the main issue.I’m a little confused on what the major issue was found to be? Was it lack of absorption material or the enclosure leakage?
I'm sorry.Alan keeps asserting that the problem is due to the OP tinkering with the speaker, but from the original post and all later posts it looks the OP only began disassembling the speaker after
Of course.Enclosure leakage mainly through the binding post appears to be the main issue.
Secondary thing was a resonance that was a lot worse in one speaker of the pair but fine in the second speaker. According to manufacturer this was inherent in the woofer frame and an email was shared from purifi to acknowledge this. Speaker Manufacturer claims they have proprietary way to mitigate this which seems to involve very specific mounting bolt torques. Here is where things get convoluted though. The speaker manufacturer claims the bolt torques were hanged by the 3rd party tester prior to testing. Third party tester claims they tested the speaker as is without altering anything and only began to modify the speaker after the poor test results were discovered
Question: has it been confirmed that the original owner of the speaker did not tighten the speaker mounting bolts in an effort to fix the speaker which was presumably noisy from the air leak???
Sample B had no distortion problems.But if I understand correctly, Sample B did not have the distortion issue?
Meaning the binding post "sealing issue", may have been, or not have been the issue all along?
The "disappointment" is more likely to be produced by this kind of reviews rather than the listening experience in itself: "stupid me, these speakers suck indeed!"If one decides to buy expensive speakers made from SOTA drivers and expect really low measurable distortion in both speakers of pair, i'd not call his disappointment "over emphasing minor issues".
Sample B had no distortion problems.
We'll know the truth to see the future production of Sointuva.
If they will be exactly the same as before, or if Alan will make any change based on OP's findings.
Finger crossed.
I am guessing you could do the repair by removing the passive radiator on the back and not touch the wooferIs it not necessary to remove/untorque the drivers to get access to the area to properly secure the posts? If Alan admits the posts were a problem and were his fault, and even offered a discount because it was cheaper for both him and the customer/OP to fix it on their own, surely he would have known that the precise torque values that are supposedly deliberately set (and are inherent to the integrity of the speaker's performance) would have been disrupted regardless? In that case he should he not at least provided these values to the OP/owner as part of the self-repair "deal", or offered to fix it himself if that information is IP he wanted to keep under wraps? Without bringing up the other little problems, it seems as though Alan is blaming customer/OP for creating a secondary problem after essentially getting his authority/blessing to fix the first one.
Nobody can open the Sointuva to check, it will ruin the secret sauce. They have to believe it is fixed.
Well, disappointment is, by definition, highly subjective so I'd say you're both totally correct and very wrong at the same time. Some of us are "disappointed" when joined wood veneers don't have perfect grain alignment or a new TV arrives with fingerprints all over the screen... while others find beauty in the "uniqueness" of a lopsided vase that can't even hold water.The "disappointment" is more likely to be produced by this kind of reviews rather than the listening experience in itself: "stupid me, these speakers suck indeed!"
Another question might be defective manufacturing, which audible or not audible ( in this case probably not...), is simply unacceptable and at any price point.
Push in on the woofer while nothing is connected to the speaker. If the passive radiator pushes out, you probably have a good seal including the binding posts.
What do you mean "the secret sauce"? If you're talking about bolt torque, manufactures should publish the recommended torque like all the car manufactures do.Nobody can open the Sointuva to check, it will ruin the secret sauce. They have to believe it is fixed.
But he didn't. The end. And the cabling stuff you'll ruin it if you pull the unit.What do you mean "the secret sauce"? If you're talking about bolt torque, manufactures should publish the recommended torque like all the car manufactures do.
Sounds like a typical high-end audio voodoo...But he didn't. The end. And the cabling stuff you'll ruin it if you pull the unit.
