Speaker Sound Quality: Crimping Is Better Than Soldering

Speaker Cable Connections : crimping is better than soldering

There are generally two types of wiring for speakers: crimping and welding. There are many articles about this on the Internet, so I won’t repeat it here.

Today we share the experimental conclusions of our engineering.
Under the same conditions, the sound performance of crimped speakers is better than that of soldered ones.

The specific experimental conditions are as follows
The test speakers were a pair of passive coaxial bookshelf boxes, one crimped to the amplifier and the other soldered.
The test song is the Chinese folk song "Northern Spring", and the volume is 60%.
The vocals and music of this song are relatively layered.

We found that crimp speakers exhibited a more natural, bright and transparent sound.
Soldered speakers, on the other hand, sound harsh and lack penetration.

Were these tests sighted? Seems unlikely your results are true. You are basically talking about attached bare wire and tinned wire ends. If audible it would be measureable. Did you attempt to measure the signals thru the two different contact methods?

Aha. Good to know it was 60 %. Then I am able to repeat the experiment at home myself and come to the same conclusions..

more natural, bright and transparent // harsh and lack penetration

When you measured these differences, where on the frequency spectrum would you say these descriptions fit exactly?

Good soldering can be learned.

And I declare that rusted coat hangers secured with chewing gum sound better than either. No actual proof or academic credentials but it must be true because I heard it.

This is a very simple experiment that you can arrange and test if you have time.

The sound difference between the two is obvious.
The sound of the speaker with welding will be relatively stiff, of course this is relative.

By the way, the test results may be somewhat subjective and limited to a few of our testers.

Soldered speakers, on the other hand, sound harsh and lack penetration.

So probably limpdick sounding ?

Somewhat subjective!?

It is so ridiculous - LOL

The difference in sound between the two is also quite obvious.

 

[Eckerslad]

The acoustics of the room are probably different at the left and right speaker. Is the test repeatable with the channels reversed?

 

[solderdude]

So yes... they were sighted.

The sound difference between the two is obvious.

So there is no need to test this 'blind'.

The sound of the speaker with welding will be relatively stiff, of course this is relative.

So better penetration .... ?

Yes... a LOT of somewhat.

Sounds lige mutual exclusives but I digress..

Please check the post sir.

Must be a real hassle to tear down a new speaker to redo the crossover connections from solder to crimped connections. Let alone the amplifier internals. Does it also apply to the CD player and streamer?

 

[BR52]

If we're removing all solder from our PCB's in DAC's, amps, we will have less harsh sound. Crimping SMD.

 

[SIY]

Don't call this an experiment- it's not. No basic controls. This certainly does not help the credibility of the products you're peddling.

 

[solderdude]

Crimping can be done everywhere and does not require gas or electricity. Just the right tool is needed, which are pretty expensive (the good ones for making proper connections). This makes it handy and fast to use especially in the field.

Both soldering and crimping can make anything from a poor connection to a good connection.

The 'sound quality' aspects, if there are any, would be very measurable.

suggest, if you want to convince ASR inhabitants, you find a way to bring some irrefutable evidence in the form of measurements rather than having to take someone's word on it from a flawed, sighted listening test.

Were connections to the speaker drivers soldered or crimped slip ons?

 

[solderdude]

and... were the flexible wires from the voicecoil to the connections also crimped (so by passing the solderjoint at the speaker terminals)
