PS Audio sent Erin their speaker??!!

This ones?

I see 4 screws in each driver.
Or is it another version?

yeah he said '' aside from the drivers '', i also thinked that. But i don't know why write that and then '' aside from the drivers '' xD

Now compare that with these KEFs at the same (to higher) price range as the Ascends:

See the rings?
The little details.

Those Heco speakers you posted pictures of are awful. Look terrible. The chrome is so tacky. Garish. Trashy.

I mean it's okay to have incorrect aesthetic taste but... we are talking more about craftsmanship quality rather than aesthetics hahaha

My point wasn’t to be a dick. Just to show we all have different taste.
Try to get any cabinet maker to copy a set of high end speaker boxes for you from scratch, and they will cost you more than that set of speakers likely. There is a lot of money in the cabinets. Whether slick and looking like the were fabricated by the Star Trek replicator or if they show some evidence of hand work by a human. I prefer the latter. Details like exposed screws are even subjective. If everything is hidden, any suggestions of the method of manufacturing then the speaker is too sterile looking for me. And too obviously a product of a factory. But that’s just my taste. Trim rings meh.

No, they produce a minimum diffraction that doesn't matter but objectively is better to not have these screw

I see 4 screws in each driver and that's what I'm talking about,that's what these rings I posted above are for.
Or is it another version?

That's perfectly fine with me. That's probably, vast majority of the speakers out there.

 

[Gringoaudio1]

Given that the wavelength of higher frequency sounds that can be heard by a human are 2-3 cm long, how can mounting screws for the drivers, which may have irregularities on the fasteners for the screwdriver on the order of mere millimeters have any diffraction effects that are audible? But perhaps they can. I need to study diffraction I guess. I will look into this. Thanks.

 

[b407driver]

It really irrelevant which order this is done in... the measurements are not going to change.

No, but the subjective opinion might.

Just to be clear, i said '' doesnt matter but obj is better to not have ''
cheers

 

[Sokel]

I hope I'm not misunderstood here,I'm not talking about performance.
If for example I was to choose between the perfectly hidden and designed for performance 8361A and the brutal 1235A with its 31786482764 screws I would go for the big boys in a heartbeat.

On the other hand I know they are not designed for living rooms but I have a big dedicated to stuff them in

 

[BrokenEnglishGuy]

That's why wives control that bad aesthetic enjoyment
haha cheers

Bingo.

In order for an object to significantly affect a soundwave it needs to big enough to do so, and "big enough to do so" turns out to be a minimum of 1/4 wavelength. A 20 kHz soundwave is about 17 millimeters long, so anything less than 4.25 millimeters across is going be effectively invisible at 20 kHz.

So some screw heads might have a little bit of effect if they are not flush with the surface or nearly so, assuming they are actually illuminated by the tweeter... most tweeters will be beaming their little hearts out at 20 kHz.

 

[JSmith]

No, but the subjective opinion might.

But the purpose is not subjective opinion without basis, it's to correlate the measurements with listening. Hence why this is done in mono... here's a vid Amir did which may clear up a few things for some;

I’m surprised there is not a suitable expensive audio tweak for such things, perhaps a nano gel (repackaged bathroom mastic) to fill in screw heads on speakers

Oh,there are ready made ones for repackaging,no need for hacks:



(there are literally thousands for every type of screw)

Engineering imagination is a marvelous thing.

 

[Gringoaudio1]

I’ve seen felt rings around tweeters on DIYAUDIO. Is that what that is for? Also often cut in patterns with a radial series of points aimed at the center of the tweeter.

Woofer or mid surrounds usually are not protruding much more than those 4 mm but still their effect is measurable both on-axis due to the symmetry as well off-axis which is one of the reasons many try to eliminate that issue with flat surrounds. Of course with screws heads it will be even less and probably not audible but still measurable.

 

[sigbergaudio]

I would obviously say that since we make speakers with visible screws, but to me the issue of screws isn't because we couldn't hide them, but because I like the functional look.

So to me, visible / hidden screws is yet another design choice, not necessarily about price/cost.

And that was my conclusion too, when I bought the Seas DXT tweeter. It might look nicer, and you can measure it, but it won't be audibly noticeable:

A lot has to do with looks and standing out. And I believe that especially KEF does it to firstly give the tweeter in the coax a smooth exit, and then make the woofers have the same look/design, simply to make the whole speaker more sleek.
