Radiant Acoustics Clarity 6.2 - Purifi based compact speaker

Still, it's a two way, whereas the 420 is a three way. Amir doesn't measure IMD, but having a different driver handle bass means the mid driver doesn't have to contend with the IMD from producing bass. I have zero doubt that IMD is lower on the 420. I don't know at which volume level this becomes audible though.
I have plenty of doubt. The IMD on the Radiant is quite amazing below 600Hz and above 5kHz, and competitive in mids too. Plenty of 3-ways comparable to KH420 do worse
In the bass region, sure - I said midrange though.
Sure, my point was that the KH420 is slightly worse in mids and way worse in bass
 
I love these.

Banana only is a miss .

But note the absence of biwiring terminals :) thankyou thankyou .

Between 2 and 4 kHz is the most sensitive range of the human ear, and if we extend a little, between 600 Hz and 5 kHz is a very sensitive range too.

That's why some speaker design try to place their crossover at the extremes of that range. Though that's probably not optimal for a number of driver sizes and their directivity.
 
Yup, if it measures the same, it'll sound the same. Measurement instruments go far beyond the limits of human hearing.

You don't need fancy cables. Sufficiently low resistance, capacitance and inductance such that any measureable (or calculated, the mathematics of impedance calculation is quite simple) difference the cable may make is below the threshold of human hearing. Capacitance has to be ridiculously high to be in any way significant relative to speaker impedance, inductance less so, but still has to be significant.

My speakers are wired with Canare 4S11 starquad. Left speaker, 3.8m long, resistance of 0.0342 Ω, inductance of 0.5 μH, capacitance of 537.4 pF. Right speaker 2.4 m long, resistance of 0.0216 Ω, inductance of 0.3 μH, capacitance of 323.7 pF. It costs about $10/m and when used properly, each pair has a CSA of 4.3 mm² ~11 AWG. The impedance of rhe cables is negligible compared to the speakers.

Internal speaker wiring is so short, provided it's of sufficient gauge, price per metre is irrelevant.

Decently made film caps are essentially all the same and will measure and perform the same.

Claims made by "High-end" manufacturers are just that. It's pure marketing with no foundation in science.

A lot of DIYers buy into the hype too. None of them do proper measurements or properly controlled blind listsning tests to really objectively test their beliefs.

People worry about tolerances of components - film cap tolerances are perfectly adequate and usually exceed the manufacturer's specification by a comfortable margin. Speaker drive unit tolerances are generally considerably worse. Unit to unit variation can seem quite significant, though in practice, from an audibility perspective, it's still nothing to worry about.

Intersting thread with a link to some proper manufacturer data on harmonic distortion figures for aluminium electrolytics:


And another thread here examining capacitor differences:

I mostly agree but changing the standard Vishay capacitors/resistors to Panasonic/Claritycap/Mundorf in my amplifier made a massive difference in sound quality.

And you compared them with properly conducted blind, level-matched listening tests?

No, you changed them, and based on your expectation bias, you convinced yourself that the amplifier sounded better.

Resistors and capacitors simply can't make a "massive" difference provided you changed with the same values with similar tolerances. Measurements show that any measurable difference (which of itself is very small) is significantly below the threshold of human hearing.

Did you read the other threads I linked to?

Did you read the other threads I linked to?
Yes I compared them because if have two identical amps
 
Well that's something, but did you compare them blind and accurately level-matched?
The difference is actually quite big so your hear it immediately from the first note.
I upgraded the parts gradually, the sound difference was 99% created by changing the caps in the signal path to Panasonic + Claritycap.
Resistors (Mundorf) + larger caps power supply (Mundorf) + internal cabling didn´t bring any further noticable difference (only in my head = peace of mind haha)
 
Can we get back on topic, pls, before this turns into dumpster fire?
To prevent more dumpster fire .

Our member @ctrl has a wonderful series of articles about capacitors here is one of them . it has links to several others on the same topic.


Lets get back on topic on these speakers
 
[...] The front baffle is 28 mm bonded with the 15 mm aluminum baffle. [...]

@henz May I ask how it is bonded? For replacing the woofer one would need to remove the aluminium front is this possible or is the whole speaker to be replaced if the woofer is broken?

It's screwed together from the inside of the cabinet. Woofers can be replaced but we'd rather do it locally in our service department. However, Purifi woofers are notoriously hard to kill so we don't believe it's going to happen very often, if at all :)
